rray": [[1,2,3,4]] } }' Using a Service ConnectorTo set up the Seldon Core Model Deployer to authenticate to a remote Kubernetes cluster, it is recommended to leverage the many features provided by the Service Connectors such as auto-configuration, local client login, best security practices regarding long-lived credentials and fine-grained access control and reusing the same credentials across multiple stack components. Depending on where your target Kubernetes cluster is running, you can use one of the following Service Connectors: the AWS Service Connector, if you are using an AWS EKS cluster. the GCP Service Connector, if you are using a GKE cluster. the Azure Service Connector, if you are using an AKS cluster. the generic Kubernetes Service Connector for any other Kubernetes cluster. If you don't already have a Service Connector configured in your ZenML deployment, you can register one using the interactive CLI command. You have the option to configure a Service Connector that can be used to access more than one Kubernetes cluster or even more than one type of cloud resource: zenml service-connector register -i A non-interactive CLI example that leverages the AWS CLI configuration on your local machine to auto-configure an AWS Service Connector targeting a single EKS cluster is: zenml service-connector register <CONNECTOR_NAME> --type aws --resource-type kubernetes-cluster --resource-name <EKS_CLUSTER_NAME> --auto-configure Example Command Output $ zenml service-connector register eks-zenhacks --type aws --resource-type kubernetes-cluster --resource-id zenhacks-cluster --auto-configure β Ό Registering service connector 'eks-zenhacks'...

Associate a pipeline with a Model The most common use-case for a Model is to associate it with a pipeline. from zenml import pipeline from zenml.model.model import Model @pipeline( model=Model( name="ClassificationModel", # Give your models unique names tags=["MVP", "Tabular"] # Use tags for future filtering def my_pipeline(): ... This will associate this pipeline with the model specified. In case the model already exists, this will create a new version of that model. In case you want to attach the pipeline to an existing model version, specify this as well. from zenml import pipeline from zenml.model.model import Model from zenml.enums import ModelStages @pipeline( model=Model( name="ClassificationModel", # Give your models unique names tags=["MVP", "Tabular"], # Use tags for future filtering version=ModelStages.LATEST # Alternatively use a stage: [STAGING, PRODUCTION]] def my_pipeline(): ...

Disable colorful logging How to disable colorful logging in ZenML. By default, ZenML uses colorful logging to make it easier to read logs. However, if you wish to disable this feature, you can do so by setting the following environment variable: ZENML_LOGGING_COLORS_DISABLED=true Note that setting this on the client environment (e.g. your local machine which runs the pipeline) will automatically disable colorful logging on remote pipeline runs. If you wish to only disable it locally, but turn on for remote pipeline runs, you can set the ZENML_LOGGING_COLORS_DISABLED environment variable in your pipeline runs environment as follows: docker_settings = DockerSettings(environment={"ZENML_LOGGING_COLORS_DISABLED": "false"}) # Either add it to the decorator @pipeline(settings={"docker": docker_settings}) def my_pipeline() -> None: my_step() # Or configure the pipelines options my_pipeline = my_pipeline.with_options( settings={"docker": docker_settings} PreviousDisable rich traceback output NextHandle Data/Artifacts Last updated 15 days ago

ter an S3 Artifact Store and add it to your stack:zenml integration install s3 -y The only configuration parameter mandatory for registering an S3 Artifact Store is the root path URI, which needs to point to an S3 bucket and take the form s3://bucket-name. Please read the documentation relevant to the S3 service that you are using on how to create an S3 bucket. For example, the AWS S3 documentation is available here. With the URI to your S3 bucket known, registering an S3 Artifact Store and using it in a stack can be done as follows: # Register the S3 artifact-store zenml artifact-store register s3_store -f s3 --path=s3://bucket-name # Register and set a stack with the new artifact store zenml stack register custom_stack -a s3_store ... --set Depending on your use case, however, you may also need to provide additional configuration parameters pertaining to authentication or pass advanced configuration parameters to match your S3-compatible service or deployment scenario. Infrastructure Deployment An S3 Artifact Store can be deployed directly from the ZenML CLI: zenml artifact-store deploy s3-artifact-store --flavor=s3 --provider=aws ... You can pass other configurations specific to the stack components as key-value arguments. If you don't provide a name, a random one is generated for you. For more information about how to work use the CLI for this, please refer to the dedicated documentation section. Authentication Methods Integrating and using an S3-compatible Artifact Store in your pipelines is not possible without employing some form of authentication. If you're looking for a quick way to get started locally, you can use the Implicit Authentication method. However, the recommended way to authenticate to the AWS cloud platform is through an AWS Service Connector. This is particularly useful if you are configuring ZenML stacks that combine the S3 Artifact Store with other remote stack components also running in AWS.

OUP> --project=<PROJECT> \ --token=<GITLAB_TOKEN>where <NAME> is the name of the code repository you are registering, <GROUP> is the group of the project, <PROJECT> is the name of the project, <GITLAB_TOKEN> is your GitLab Personal Access Token, and <GITLAB_URL> is the URL of the GitLab instance which defaults to https://gitlab.com. You will need to set a URL if you have a self-hosted GitLab instance. After registering the GitLab code repository, ZenML will automatically detect if your source files are being tracked by GitLab and store the commit hash for each pipeline run. Go to your GitLab account settings and click on Access Tokens. Name the token and select the scopes that you need (e.g. read_repository, read_user, read_api) Click on "Create personal access token" and copy the token to a safe place. Developing a custom code repository If you're using some other platform to store your code, and you still want to use a code repository in ZenML, you can implement and register a custom code repository. First, you'll need to subclass and implement the abstract methods of the zenml.code_repositories.BaseCodeRepository class: class BaseCodeRepository(ABC): """Base class for code repositories.""" @abstractmethod def login(self) -> None: """Logs into the code repository.""" @abstractmethod def download_files( self, commit: str, directory: str, repo_sub_directory: Optional[str] ) -> None: """Downloads files from the code repository to a local directory.

Storing embeddings in a vector database Store embeddings in a vector database for efficient retrieval. The process of generating the embeddings doesn't take too long, especially if the machine on which the step is running has a GPU, but it's still not something we want to do every time we need to retrieve a document. Instead, we can store the embeddings in a vector database, which allows us to quickly retrieve the most relevant chunks based on their similarity to the query. For the purposes of this guide, we'll use PostgreSQL as our vector database. This is a popular choice for storing embeddings, as it provides a scalable and efficient way to store and retrieve high-dimensional vectors. However, you can use any vector database that supports high-dimensional vectors. If you want to explore a list of possible options, this is a good website to compare different options. For more information on how to set up a PostgreSQL database to follow along with this guide, please see the instructions in the repository which show how to set up a PostgreSQL database using Supabase. Since PostgreSQL is a well-known and battle-tested database, we can use known and minimal packages to connect and to interact with it. We can use the psycopg2 package to connect and then raw SQL statements to interact with the database. The code for the step is fairly simple: from zenml import step @step def index_generator( documents: List[Document], ) -> None: try: conn = get_db_conn() with conn.cursor() as cur: # Install pgvector if not already installed cur.execute("CREATE EXTENSION IF NOT EXISTS vector") conn.commit() # Create the embeddings table if it doesn't exist table_create_command = f""" CREATE TABLE IF NOT EXISTS embeddings ( id SERIAL PRIMARY KEY, content TEXT, token_count INTEGER, embedding VECTOR({EMBEDDING_DIMENSIONALITY}), filename TEXT, parent_section TEXT, url TEXT ); """ cur.execute(table_create_command) conn.commit() register_vector(conn)

Controlling Model versions Each model can have many versions. Model versions are a way for you to track different iterations of your training process, complete with some extra dashboard and API functionality to support the full ML lifecycle. E.g. Based on your business rules during training, you can associate model version with stages and promote them to production. You have an interface that allows you to link these versions with non-technical artifacts and data, e.g. business data, datasets, or even stages in your process and workflow. Model versions are created implicitly as you are running your machine learning training, so you don't have to immediately think about this. If you want more control over versions, our API has you covered, with an option to explicitly name your versions. Explicitly name your model version If you want to explicitly name your model version, you can do so by passing in the version argument to the Model object. If you don't do this, ZenML will automatically generate a version number for you. from zenml import Model, step, pipeline model= Model( name="my_model", version="1.0.5" # The step configuration will take precedence over the pipeline @step(model=model) def svc_trainer(...) -> ...: ... # This configures it for all steps within the pipeline @pipeline(model=model) def training_pipeline( ... ): # training happens here Here we are specifically setting the model configuration for a particular step or for the pipeline as a whole. Please note in the above example if the model version exists, it is automatically associated with the pipeline and becomes active in the pipeline context. Therefore, a user should be careful and intentional as to whether you want to create a new pipeline, or fetch an existing one. See below for an example of fetching a model from an existing version/stage. Fetching model versions by stage

nML, namely an orchestrator and an artifact store.Keep in mind, that each one of these components is built on top of base abstractions and is completely extensible. Orchestrator An Orchestrator is a workhorse that coordinates all the steps to run in a pipeline. Since pipelines can be set up with complex combinations of steps with various asynchronous dependencies between them, the orchestrator acts as the component that decides what steps to run and when to run them. ZenML comes with a default local orchestrator designed to run on your local machine. This is useful, especially during the exploration phase of your project. You don't have to rent a cloud instance just to try out basic things. Artifact Store An Artifact Store is a component that houses all data that pass through the pipeline as inputs and outputs. Each artifact that gets stored in the artifact store is tracked and versioned and this allows for extremely useful features like data caching which speeds up your workflows. Similar to the orchestrator, ZenML comes with a default local artifact store designed to run on your local machine. This is useful, especially during the exploration phase of your project. You don't have to set up a cloud storage system to try out basic things. Flavor ZenML provides a dedicated base abstraction for each stack component type. These abstractions are used to develop solutions, called Flavors, tailored to specific use cases/tools. With ZenML installed, you get access to a variety of built-in and integrated Flavors for each component type, but users can also leverage the base abstractions to create their own custom flavors. Stack Switching When it comes to production-grade solutions, it is rarely enough to just run your workflow locally without including any cloud infrastructure.

heck out this 3-minute video for more information.You can keep changing the Config and Settings of your flavor after registration. ZenML will pick up these "live" changes when running pipelines. Note that changing the config in a breaking way requires an update of the component (not a flavor). E.g., adding a mandatory name to flavor X field will break a registered component of that flavor. This may lead to a completely broken state where one should delete the component and re-register it. Always test your flavor thoroughly before using it in production. Make sure it works as expected and handles errors gracefully. Keep your flavor code clean and well-documented. This will make it easier for others to use and contribute to your flavor. Follow best practices for the language and libraries you're using. This will help ensure your flavor is efficient, reliable, and easy to maintain. We recommend you develop new flavors by using existing flavors as a reference. A good starting point is the flavors defined in the official ZenML integrations.

. Authentication Methods Implicit authenticationImplicit authentication to AWS services using environment variables, local configuration files or IAM roles. This method may constitute a security risk, because it can give users access to the same cloud resources and services that the ZenML Server itself is configured to access. For this reason, all implicit authentication methods are disabled by default and need to be explicitly enabled by setting the ZENML_ENABLE_IMPLICIT_AUTH_METHODS environment variable or the helm chart enableImplicitAuthMethods configuration option to true in the ZenML deployment. This authentication method doesn't require any credentials to be explicitly configured. It automatically discovers and uses credentials from one of the following sources: environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, AWS_DEFAULT_REGION) local configuration files set up through the AWS CLI (~/aws/credentials, ~/.aws/config) IAM roles for Amazon EC2, ECS, EKS, Lambda, etc. Only works when running the ZenML server on an AWS resource with an IAM role attached to it. This is the quickest and easiest way to authenticate to AWS services. However, the results depend on how ZenML is deployed and the environment where it is used and is thus not fully reproducible: when used with the default local ZenML deployment or a local ZenML server, the credentials are the same as those used by the AWS CLI or extracted from local environment variables when connected to a ZenML server, this method only works if the ZenML server is deployed in AWS and will use the IAM role attached to the AWS resource where the ZenML server is running (e.g. an EKS cluster). The IAM role permissions may need to be adjusted to allow listing and accessing/describing the AWS resources that the connector is configured to access.

This component is only meant to be used within the context of a remote ZenML deployment scenario. Usage with a local ZenML deployment may lead to unexpected behavior! When to use it You should use the HyperAI orchestrator if: you're looking for a managed solution for running your pipelines. you're a HyperAI customer. Prerequisites You will need to do the following to start using the HyperAI orchestrator: Have a running HyperAI instance. It must be accessible from the internet (or at least from the IP addresses of your ZenML users) and allow SSH key based access (passwords are not supported). Ensure that a recent version of Docker is installed. This version must include Docker Compose, meaning that the command docker compose works. Ensure that the appropriate NVIDIA Driver is installed on the HyperAI instance (if not already installed by the HyperAI team). Ensure that the NVIDIA Container Toolkit is installed and configured on the HyperAI instance. Note that it is possible to omit installing the NVIDIA Driver and NVIDIA Container Toolkit. However, you will then be unable to use the GPU from within your ZenML pipeline. Additionally, you will then need to disable GPU access within the container when configuring the Orchestrator component, or the pipeline will not start correctly. How it works

: zenml model-registry flavor list How to use itModel registries are an optional component in the ZenML stack that is tied to the experiment tracker. This means that a model registry can only be used if you are also using an experiment tracker. If you're not using an experiment tracker, you can still store your models in ZenML, but you will need to manually retrieve model artifacts from the artifact store. More information on this can be found in the documentation on the fetching runs. To use model registries, you first need to register a model registry in your stack with the same flavor as your experiment tracker. Then, you can register your trained model in the model registry using one of three methods: (1) using the built-in step in the pipeline. (2) using the ZenML CLI to register the model from the command line. (3) registering the model from the model registry UI. Finally, you can use the model registry to retrieve and load your models for deployment or further experimentation.

e by passing the page argument to the list method.You can further restrict your search by passing additional arguments that will be used to filter the results. E.g., most resources have a user_id associated with them that can be set to only list resources created by that specific user. The available filter argument options are different for each list method; check out the method declaration in the Client SDK documentation to find out which exact arguments are supported or have a look at the fields of the corresponding filter model class. Except for pipeline runs, all other resources will by default be ordered by creation time ascending. E.g., client.list_artifacts() would return the first 50 artifacts ever created. You can change the ordering by specifying the sort_by argument when calling list methods. Get Methods Fetch a specific instance of a resource by either resource ID, name, or name prefix, e.g.: client.get_pipeline_run("413cfb42-a52c-4bf1-a2fd-78af2f7f0101") # ID client.get_pipeline_run("first_pipeline-2023_06_20-16_20_13_274466") # Name client.get_pipeline_run("first_pipeline-2023_06_20-16") # Name prefix Create, Update, and Delete Methods Methods for creating / updating / deleting resources are only available for some of the resources and the required arguments are different for each resource. Checkout the Client SDK Documentation to find out whether a specific resource supports write operations through the Client and which arguments are required. Active User and Active Stack For some use cases you might need to know information about the user that you are authenticated as or the stack that you have currently set as active. You can fetch this information via the client.active_user and client.active_stack_model properties respectively, e.g.: my_runs_on_current_stack = client.list_pipeline_runs( stack_id=client.active_stack_model.id, # on current stack user_id=client.active_user.id, # ran by you Resource Models

Amazon Elastic Container Registry (ECR) Storing container images in Amazon ECR. The AWS container registry is a container registry flavor provided with the ZenML aws integration and uses Amazon ECR to store container images. When to use it You should use the AWS container registry if: one or more components of your stack need to pull or push container images. you have access to AWS ECR. If you're not using AWS, take a look at the other container registry flavors. How to deploy it The ECR registry is automatically activated once you create an AWS account. However, you'll need to create a Repository in order to push container images to it: Go to the ECR website. Make sure the correct region is selected on the top right. Click on Create repository. Create a private repository. The name of the repository depends on the [orchestrator] (../orchestrators/orchestrators.md or step operator you're using in your stack. URI format The AWS container registry URI should have the following format: <ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com # Examples: 123456789.dkr.ecr.eu-west-2.amazonaws.com 987654321.dkr.ecr.ap-south-1.amazonaws.com 135792468.dkr.ecr.af-south-1.amazonaws.com To figure out the URI for your registry: Go to the AWS console and click on your user account in the top right to see the Account ID. Go here and choose the region in which you would like to store your container images. Make sure to choose a nearby region for faster access. Once you have both these values, fill in the values in this template <ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com to get your container registry URI. Infrastructure Deployment An AWS ECR Container Registry can be deployed directly from the ZenML CLI: zenml container-registry deploy ecr_container_registry --flavor=aws --provider=aws ...

━━━━━━━━━┷━━━━━━━━┛ Local and remote availabilityYou only need to be aware of local and remote availability for Service Connector Types if you are explicitly looking to use a Service Connector Type without installing its package prerequisites or if you are implementing or using a custom Service Connector Type implementation with your ZenML deployment. In all other cases, you may safely ignore this section. The LOCAL and REMOTE flags in the zenml service-connector list-types output indicate if the Service Connector implementation is available locally (i.e. where the ZenML client and pipelines are running) and remotely (i.e. where the ZenML server is running). All built-in Service Connector Types are by default available on the ZenML server, but some built-in Service Connector Types require additional Python packages to be installed to be available in your local environment. See the section documenting each Service Connector Type to find what these prerequisites are and how to install them. The local/remote availability determines the possible actions and operations that can be performed with a Service Connector. The following are possible with a Service Connector Type that is available either locally or remotely: Service Connector registration, update, and discovery (i.e. the zenml service-connector register, zenml service-connector update, zenml service-connector list and zenml service-connector describe CLI commands). Service Connector verification: checking whether its configuration and credentials are valid and can be actively used to access the remote resources (i.e. the zenml service-connector verify CLI commands). Listing the resources that can be accessed through a Service Connector (i.e. the zenml service-connector verify and zenml service-connector list-resources CLI commands) Connecting a Stack Component to a remote resource via a Service Connector

setting the VAULT_NAMESPACE environment variable.ZENML_SECRETS_STORE_MAX_VERSIONS: The maximum number of secret versions to keep for each Vault secret. If not set, the default value of 1 will be used (only the latest version will be kept). These configuration options are only relevant if you're using a custom secrets store backend implementation. For this to work, you must have a custom implementation of the secrets store API in the form of a class derived from zenml.zen_stores.secrets_stores.base_secrets_store.BaseSecretsStore. This class must be importable from within the ZenML server container, which means you most likely need to mount the directory containing the class into the container or build a custom container image that contains the class. The following configuration option is required: ZENML_SECRETS_STORE_TYPE: Set this to custom in order to set this type of secret store. ZENML_SECRETS_STORE_CLASS_PATH: The fully qualified path to the class that implements the custom secrets store API (e.g. my_package.my_module.MySecretsStore). If your custom secrets store implementation requires additional configuration options, you can pass them as environment variables using the following naming convention: ZENML_SECRETS_STORE_<OPTION_NAME>: The name of the option to pass to the custom secrets store class. The option name must be in uppercase and any hyphens (-) must be replaced with underscores (_). ZenML will automatically convert the environment variable name to the corresponding option name by removing the prefix and converting the remaining characters to lowercase. For example, the environment variable ZENML_SECRETS_STORE_MY_OPTION will be converted to the option name my_option and passed to the custom secrets store class configuration. ZENML_SECRETS_STORE_TYPE: Set this variable to noneto disable the secrets store functionality altogether. Backup secrets store

Specify pip dependencies and apt packages The configuration for specifying pip and apt dependencies only works in the remote pipeline case, and is disregarded for local pipelines (i.e. pipelines that run locally without having to build a Docker image). When a pipeline is run with a remote orchestrator a Dockerfile is dynamically generated at runtime. It is then used to build the Docker image using the image builder component of your stack. By default, ZenML automatically installs all packages required by your active ZenML stack. However, you can specify additional packages to be installed in various ways: Install all the packages in your local Python environment (This will use the pip or poetry package manager to get a list of your local packages): # or use "poetry_export" docker_settings = DockerSettings(replicate_local_python_environment="pip_freeze") @pipeline(settings={"docker": docker_settings}) def my_pipeline(...): ... If required, a custom command can be provided. This command must output a list of requirements following the format of the requirements file: docker_settings = DockerSettings(replicate_local_python_environment=[ "poetry", "export", "--extras=train", "--format=requirements.txt" ]) @pipeline(settings={"docker": docker_settings}) def my_pipeline(...): ...

Understanding stacks Learning how to switch the infrastructure backend of your code. Now that we have ZenML deployed, we can take the next steps in making sure that our machine learning workflows are production-ready. As you were running your first pipelines, you might have already noticed the term stack in the logs and on the dashboard. A stack is the configuration of tools and infrastructure that your pipelines can run on. When you run ZenML code without configuring a stack, the pipeline will run on the so-called default stack. Separation of code from configuration and infrastructure As visualized in the diagram above, there are two separate domains that are connected through ZenML. The left side shows the code domain. The user's Python code is translated into a ZenML pipeline. On the right side, you can see the infrastructure domain, in this case, an instance of the default stack. By separating these two domains, it is easy to switch the environment that the pipeline runs on without making any changes in the code. It also allows domain experts to write code/configure infrastructure without worrying about the other domain. The default stack zenml stack describe lets you find out details about your active stack: ...

This allows for fine-grained control over the resources allocated to each step, ensuring that each part of your pipeline has the necessary compute power while optimizing for cost and efficiency. Configuring Step-Specific Resources The SkyPilot VM Orchestrator allows you to configure resources for each step individually. This means you can specify different VM types, CPU and memory requirements, and even use spot instances for certain steps while using on-demand instances for others.

View logs on the dashboard By default, ZenML uses a logging handler to capture the logs that occur during the execution of a step. Users are free to use the default python logging module or print statements, and ZenML's logging handler will catch these logs and store them. import logging from zenml import step @step def my_step() -> None: logging.warning("`Hello`") # You can use the regular `logging` module. print("World.") # You can utilize `print` statements as well. These logs are stored within the respective artifact store of your stack. This means that you can only view these logs in the dashboard if the deployed ZenML server has direct access to the underlying artifact store. There are two cases in which this will be true: In case of a local ZenML server (via zenml up), both local and remote artifact stores may be accessible, depending on configuration of the client. In case of a deployed ZenML server, logs for runs on a local artifact store will not be accessible. Logs for runs using a remote artifact store may be accessible, if the artifact store has been configured with a service connector. Please read this chapter of the production guide to learn how to configure a remote artifact store with a service connector. If configured correctly, the logs are displayed in the dashboard as follows: If you do not want to store the logs for your pipeline (for example due to performance reduction or storage limits), you can follow these instructions.

Manage artifacts Understand and adjust how ZenML versions your data. Data sits at the heart of every machine learning workflow. Managing and versioning this data correctly is essential for reproducibility and traceability within your ML pipelines. ZenML takes a proactive approach to data versioning, ensuring that every artifactβ€”be it data, models, or evaluationsβ€”is automatically tracked and versioned upon pipeline execution. This guide will delve into artifact versioning and management, showing you how to efficiently name, organize, and utilize your data with the ZenML framework. Managing artifacts produced by ZenML pipelines Artifacts, the outputs of your steps and pipelines, are automatically versioned and stored in the artifact store. Configuring these artifacts is pivotal for transparent and efficient pipeline development. Giving names to your artifacts Assigning custom names to your artifacts can greatly enhance their discoverability and manageability. As best practice, utilize the Annotated object within your steps to give precise, human-readable names to outputs: from typing_extensions import Annotated import pandas as pd from sklearn.datasets import load_iris from zenml import pipeline, step # Using Annotated to name our dataset @step def training_data_loader() -> Annotated[pd.DataFrame, "iris_dataset"]: """Load the iris dataset as pandas dataframe.""" iris = load_iris(as_frame=True) return iris.get("frame") @pipeline def feature_engineering_pipeline(): training_data_loader() if __name__ == "__main__": feature_engineering_pipeline() Unspecified artifact outputs default to a naming pattern of {pipeline_name}::{step_name}::output. For visual exploration in the ZenML dashboard, it's best practice to give significant outputs clear custom names. Artifacts named iris_dataset can then be found swiftly using various ZenML interfaces: To list artifacts: zenml artifact list

Deploy with custom images Deploying ZenML with custom Docker images. In most cases, deploying ZenML with the default zenmlhub/zenml-server Docker image should work just fine. However, there are some scenarios when you might need to deploy ZenML with a custom Docker image: You have implemented a custom artifact store for which you want to enable artifact visualizations or step logs in your dashboard. You have forked the ZenML repository and want to deploy a ZenML server based on your own fork because you made changes to the server / database logic. Deploying ZenML with custom Docker images is only possible for Docker or Helm deployments. Build and Push Custom ZenML Server Docker Image Here is how you can build a custom ZenML server Docker image: Set up a container registry of your choice. E.g., as an indivial developer you could create a free Docker Hub account and then set up a free Docker Hub repository. Clone ZenML (or your ZenML fork) and checkout the branch that you want to deploy, e.g., if you want to deploy ZenML version 0.41.0, runCopygit checkout release/0.41.0 Copy the ZenML base.Dockerfile, e.g.:Copycp docker/base.Dockerfile docker/custom.Dockerfile Modify the copied Dockerfile:Add additional dependencies:CopyRUN pip install <my_package>(Forks only) install local files instead of official ZenML:CopyRUN pip install -e .[server,secrets-aws,secrets-gcp,secrets-azure,secrets-hashicorp,s3fs,gcsfs,adlfs,connectors-aws,connectors-gcp,connectors-azure] Build and push an image based on your Dockerfile:Copydocker build -f docker/custom.Dockerfile . -t <YOUR_CONTAINER_REGISTRY>/<IMAGE_NAME>:<IMAGE_TAG> --platform linux/amd64 docker push <YOUR_CONTAINER_REGISTRY>/<IMAGE_NAME>:<IMAGE_TAG> If you want to verify your custom image locally, you can follow the Deploy a custom ZenML image via Docker section below to deploy the ZenML server locally first.

kdownString .csv / .html / .md (depending on type)ZenML provides a built-in CloudpickleMaterializer that can handle any object by saving it with cloudpickle. However, this is not production-ready because the resulting artifacts cannot be loaded when running with a different Python version. In such cases, you should consider building a custom Materializer to save your objects in a more robust and efficient format. Moreover, using the CloudpickleMaterializer could allow users to upload of any kind of object. This could be exploited to upload a malicious file, which could execute arbitrary code on the vulnerable system. Integration Materializers In addition to the built-in materializers, ZenML also provides several integration-specific materializers that can be activated by installing the respective integration:

Understanding reranking Understand how reranking works. What is reranking? Reranking is the process of refining the initial ranking of documents retrieved by a retrieval system. In the context of Retrieval-Augmented Generation (RAG), reranking plays a crucial role in improving the relevance and quality of the retrieved documents that are used to generate the final output. The initial retrieval step in RAG typically uses a sparse retrieval method, such as BM25 or TF-IDF, to quickly find a set of potentially relevant documents based on the input query. However, these methods rely on lexical matching and may not capture the semantic meaning or context of the query effectively. Rerankers, on the other hand, are designed to reorder the retrieved documents by considering additional features, such as semantic similarity, relevance scores, or domain-specific knowledge. They aim to push the most relevant and informative documents to the top of the list, ensuring that the LLM has access to the best possible context for generating accurate and coherent responses. Types of Rerankers There are different types of rerankers that can be used in RAG, each with its own strengths and trade-offs: Cross-Encoders: Cross-encoders are a popular choice for reranking in RAG. They take the concatenated query and document as input and output a relevance score. Examples include BERT-based models fine-tuned for passage ranking tasks. Cross-encoders can capture the interaction between the query and document effectively but are computationally expensive. Bi-Encoders: Bi-encoders, also known as dual encoders, use separate encoders for the query and document. They generate embeddings for the query and document independently and then compute the similarity between them. Bi-encoders are more efficient than cross-encoders but may not capture the query-document interaction as effectively.

s used for each run. Creating a GitHub RepositoryWhile ZenML supports many different flavors of git repositories, this guide will focus on GitHub. To create a repository on GitHub: Sign in to GitHub. Click the "+" icon and select "New repository." Name your repository, set its visibility, and add a README or .gitignore if needed. Click "Create repository." We can now push our local code (from the previous chapters) to GitHub with these commands: # Initialize a Git repository git init # Add files to the repository git add . # Commit the files git commit -m "Initial commit" # Add the GitHub remote git remote add origin https://github.com/YOUR_USERNAME/YOUR_REPOSITORY_NAME.git # Push to GitHub git push -u origin master Replace YOUR_USERNAME and YOUR_REPOSITORY_NAME with your GitHub information. Linking to ZenML To connect your GitHub repository to ZenML, you'll need a GitHub Personal Access Token (PAT). Go to your GitHub account settings and click on Developer settings. Select "Personal access tokens" and click on "Generate new token". Give your token a name and a description. We recommend selecting the specific repository and then giving contents read-only access. Click on "Generate token" and copy the token to a safe place. Now, we can install the GitHub integration and register your repository: zenml integration install github zenml code-repository register <REPO_NAME> --type=github \ --url=https://github.com/YOUR_USERNAME/YOUR_REPOSITORY_NAME.git \ --owner=YOUR_USERNAME --repository=YOUR_REPOSITORY_NAME \ --token=YOUR_GITHUB_PERSONAL_ACCESS_TOKEN Fill in <REPO_NAME>, YOUR_USERNAME, YOUR_REPOSITORY_NAME, and YOUR_GITHUB_PERSONAL_ACCESS_TOKEN with your details. Your code is now connected to your ZenML server. ZenML will automatically detect if your source files are being tracked by GitHub and store the commit hash for each subsequent pipeline run. You can try this out by running our training pipeline again: # This will build the Docker image the first time

of your models at different stages of development.if you have pipelines that regularly ingest new data, you should use data validation to run regular data integrity checks to signal problems before they are propagated downstream. in continuous training pipelines, you should use data validation techniques to compare new training data against a data reference and to compare the performance of newly trained models against previous ones. when you have pipelines that automate batch inference or if you regularly collect data used as input in online inference, you should use data validation to run data drift analyses and detect training-serving skew, data drift and model drift.

for federated users by impersonating another user.The connector needs to be configured with an AWS secret key associated with an IAM user or AWS account root user (not recommended). The IAM user must have permission to call the GetFederationToken STS API (i.e. allow the sts:GetFederationToken action on the * IAM resource). The connector will generate temporary STS tokens upon request by calling the GetFederationToken STS API. These STS tokens have an expiration period longer than those issued through the AWS IAM Role authentication method and are more suitable for long-running processes that cannot automatically re-generate credentials upon expiration. An AWS region is required and the connector may only be used to access AWS resources in the specified region. One or more optional IAM session policies may also be configured to further restrict the permissions of the generated STS tokens. If not specified, IAM session policies are automatically configured for the generated STS tokens to restrict them to the minimum set of permissions required to access the target resource. Refer to the documentation for each supported Resource Type for the complete list of AWS permissions automatically granted to the generated STS tokens. If this authentication method is used with the generic AWS resource type, a session policy MUST be explicitly specified, otherwise, the generated STS tokens will not have any permissions. The default expiration period for generated STS tokens is 12 hours with a minimum of 15 minutes and a maximum of 36 hours. Temporary credentials obtained by using the AWS account root user credentials (not recommended) have a maximum duration of 1 hour. If you need to access an EKS Kubernetes cluster with this authentication method, please be advised that the EKS cluster's aws-auth ConfigMap may need to be manually configured to allow authentication with the federated user. For more information, see this documentation.

lementation_class(self) -> Type[BaseStepOperator]:"""Returns the implementation class for this flavor.""" This is a slimmed-down version of the base implementation which aims to highlight the abstraction layer. In order to see the full implementation and get the complete docstrings, please check the SDK docs . Build your own custom step operator If you want to create your own custom flavor for a step operator, you can follow the following steps: Create a class that inherits from the BaseStepOperator class and implement the abstract launch method. This method has two main responsibilities:Preparing a suitable execution environment (e.g. a Docker image): The general environment is highly dependent on the concrete step operator implementation, but for ZenML to be able to run the step it requires you to install some pip dependencies. The list of requirements needed to successfully execute the step can be found via the Docker settings info.pipeline.docker_settings passed to the launch() method. Additionally, you'll have to make sure that all the source code of your ZenML step and pipeline are available within this execution environment.Running the entrypoint command: Actually running a single step of a pipeline requires knowledge of many ZenML internals and is implemented in the zenml.step_operators.step_operator_entrypoint_configuration module. As long as your environment was set up correctly (see the previous bullet point), you can run the step using the command provided via the entrypoint_command argument of the launch() method. If your step operator allows the specification of per-step resources, make sure to handle the resources defined on the step (info.config.resource_settings) that was passed to the launch() method. If you need to provide any configuration, create a class that inherits from the BaseStepOperatorConfig class adds your configuration parameters.

zation or use to authenticate automated workloads.In fact, cloud platforms don't even allow using user account passwords directly as a credential when authenticating to the cloud platform APIs. There is always a process in place that allows exchanging the account/password credential for another form of long-lived credential. Even when passwords are mentioned as credentials, some services (e.g. DockerHub) also allow using an API access key in place of the user account password. Implicit authentication The key takeaway here is that implicit authentication gives you immediate access to some cloud resources and requires no configuration, but it may take some extra effort to expand the range of resources that you're initially allowed to access with it. This is not an authentication method you want to use if you're interested in portability and enabling others to reproduce your results. This method may constitute a security risk, because it can give users access to the same cloud resources and services that the ZenML Server itself is configured to access. For this reason, all implicit authentication methods are disabled by default and need to be explicitly enabled by setting the ZENML_ENABLE_IMPLICIT_AUTH_METHODS environment variable or the helm chart enableImplicitAuthMethods configuration option to true in the ZenML deployment. Implicit authentication is just a fancy way of saying that the Service Connector will use locally stored credentials, configuration files, environment variables, and basically any form of authentication available in the environment where it is running, either locally or in the cloud. Most cloud providers and their associated Service Connector Types include some form of implicit authentication that is able to automatically discover and use the following forms of authentication in the environment where they are running: configuration and credentials set up and stored locally through the cloud platform CLI configuration and credentials passed as environment variables

his flavor.""" return BaseContainerRegistryConfig@property def implementation_class(self) -> Type[BaseContainerRegistry]: """Implementation class.""" return BaseContainerRegistry This is a slimmed-down version of the base implementation which aims to highlight the abstraction layer. In order to see the full implementation and get the complete docstrings, please check the SDK docs . Building your own container registry If you want to create your own custom flavor for a container registry, you can follow the following steps: Create a class that inherits from the BaseContainerRegistry class and if you need to execute any checks/validation before the image gets pushed, you can define these operations in the prepare_image_push method. As an example, you can check the AWSContainerRegistry. If you need further configuration, you can create a class which inherits from the BaseContainerRegistryConfig class. Bring both the implementation and the configuration together by inheriting from the BaseContainerRegistryFlavor class. Once you are done with the implementation, you can register it through the CLI. Please ensure you point to the flavor class via dot notation: zenml container-registry flavor register <path.to.MyContainerRegistryFlavor> For example, your flavor class MyContainerRegistryFlavor is defined in flavors/my_flavor.py, you'd register it by doing: zenml container-registry flavor register flavors.my_flavor.MyContainerRegistryFlavor ZenML resolves the flavor class by taking the path where you initialized zenml (via zenml init) as the starting point of resolution. Therefore, please ensure you follow the best practice of initializing zenml at the root of your repository. If ZenML does not find an initialized ZenML repository in any parent directory, it will default to the current working directory, but usually it's better to not have to rely on this mechanism, and initialize zenml at the root. Afterward, you should see the new flavor in the list of available flavors:

s within a unique directory in the artifact store:Materializers are designed to be extensible and customizable, allowing you to define your own serialization and deserialization logic for specific data types or storage systems. By default, ZenML provides built-in materializers for common data types and uses cloudpickle to pickle objects where there is no default materializer. If you want direct control over how objects are serialized, you can easily create custom materializers by extending the BaseMaterializer class and implementing the required methods for your specific use case. Read more about materializers here. ZenML provides a built-in CloudpickleMaterializer that can handle any object by saving it with cloudpickle. However, this is not production-ready because the resulting artifacts cannot be loaded when running with a different Python version. In such cases, you should consider building a custom Materializer to save your objects in a more robust and efficient format. Moreover, using the CloudpickleMaterializer could allow users to upload of any kind of object. This could be exploited to upload a malicious file, which could execute arbitrary code on the vulnerable system. When a pipeline runs, ZenML uses the appropriate materializers to save and load artifacts using the ZenML fileio system (built to work across multiple artifact stores). This not only simplifies the process of working with different data formats and storage systems but also enables artifact caching and lineage tracking. You can see an example of a default materializer (the numpy materializer) in action here. PreviousHandle Data/Artifacts NextReturn multiple outputs from a step Last updated 15 days ago

Troubleshoot the deployed server Troubleshooting tips for your ZenML deployment In this document, we will go over some common issues that you might face when deploying ZenML and how to solve them. Viewing logs Analyzing logs is a great way to debug issues. Depending on whether you have a Kubernetes (using Helm or zenml deploy) or a Docker deployment, you can view the logs in different ways. If you are using Kubernetes, you can view the logs of the ZenML server using the following method: Check all pods that are running your ZenML deployment. kubectl -n <KUBERNETES_NAMESPACE> get pods If you see that the pods aren't running, you can use the command below to get the logs for all pods at once. kubectl -n <KUBERNETES_NAMESPACE> logs -l app.kubernetes.io/name=zenml Note that the error can either be from the zenml-db-init container that connects to the MySQL database or from the zenml container that runs the server code. If the get pods command shows that the pod is failing in the Init state then use zenml-db-init as the container name, otherwise use zenml. kubectl -n <KUBERNETES_NAMESPACE> logs -l app.kubernetes.io/name=zenml -c <CONTAINER_NAME> You can also use the --tail flag to limit the number of lines to show or the --follow flag to follow the logs in real-time. If you are using Docker, you can view the logs of the ZenML server using the following method: If you used the zenml up --docker CLI command to deploy the Docker ZenML server, you can check the logs with the command:Copyzenml logs -f If you used the docker run command to manually deploy the Docker ZenML server, you can check the logs with the command:Copydocker logs zenml -f If you used the docker compose command to manually deploy the Docker ZenML server, you can check the logs with the command:Copydocker compose -p zenml logs -f Fixing database connection problems

ZenML will automatically create a BentoML client for you and you can use it to send requests to the deployed model by simply calling the service to predict the method and passing the input data and the API function name. The following example shows how to use the BentoML client to send requests to the deployed model. @step def predictor( inference_data: Dict[str, List], service: BentoMLDeploymentService, ) -> None: """Run an inference request against the BentoML prediction service.

However, a real-world scenario will most likely require you to deploy your model to a remote environment. The next section will show you how to deploy the Bento you built with ZenML pipelines to a cloud environment using the bentoctl CLI. From Local to Cloud with bentoctl Bentoctl helps deploy any machine learning models as production-ready API endpoints into the cloud. It is a command line tool that provides a simple interface to manage your BentoML bundles.

The connector needs to be configured with an AWS secret key associated with an IAM user or AWS account root user (not recommended). The connector will generate temporary STS tokens upon request by calling the GetSessionToken STS API. These STS tokens have an expiration period longer that those issued through the AWS IAM Role authentication method and are more suitable for long-running processes that cannot automatically re-generate credentials upon expiration. An AWS region is required and the connector may only be used to access AWS resources in the specified region. The default expiration period for generated STS tokens is 12 hours with a minimum of 15 minutes and a maximum of 36 hours. Temporary credentials obtained by using the AWS account root user credentials (not recommended) have a maximum duration of 1 hour. As a precaution, when long-lived credentials (i.e. AWS Secret Keys) are detected on your environment by the Service Connector during auto-configuration, this authentication method is automatically chosen instead of the AWS Secret Key authentication method alternative.

ds until the pipeline shows up in the Airflow UI).The ability to provision resources using the zenml stack up command is deprecated and will be removed in a future release. While it is still available for the Airflow orchestrator, we recommend following the steps to set up a local Airflow server manually. Install the apache-airflow package in your Python environment where ZenML is installed. The Airflow environment variables are used to configure the behavior of the Airflow server. The following variables are particularly important to set: AIRFLOW_HOME: This variable defines the location where the Airflow server stores its database and configuration files. The default value is ~/airflow. AIRFLOW__CORE__DAGS_FOLDER: This variable defines the location where the Airflow server looks for DAG files. The default value is <AIRFLOW_HOME>/dags. AIRFLOW__CORE__LOAD_EXAMPLES: This variable controls whether the Airflow server should load the default set of example DAGs. The default value is false, which means that the example DAGs will not be loaded. AIRFLOW__SCHEDULER__DAG_DIR_LIST_INTERVAL: This variable controls how often the Airflow scheduler checks for new or updated DAGs. By default, the scheduler will check for new DAGs every 30 seconds. This variable can be used to increase or decrease the frequency of the checks, depending on the specific needs of your pipeline.Copyexport AIRFLOW_HOME=... export AIRFLOW__CORE__DAGS_FOLDER=... export AIRFLOW__CORE__LOAD_EXAMPLES=false export AIRFLOW__SCHEDULER__DAG_DIR_LIST_INTERVAL=10 # Prevent crashes during forking on MacOS # https://github.com/apache/airflow/issues/28487 export no_proxy=* Run airflow standalone to initialize the database, create a user, and start all components for you. When using the Airflow orchestrator with a remote deployment, you'll additionally need: A remote ZenML server deployed to the cloud. See the deployment guide for more information.

ow the recommendations from the Project templates.In steps/alerts/notify_on.py, you will find a step to notify the user about success and a function used to notify the user about step failure using the Alerter from the active stack. We use @step for success notification to only notify the user about a fully successful pipeline run and not about every successful step. Inside this code file, you can find how developers can work with Al component to send notification messages across configured channels: from zenml.client import Client from zenml import get_step_context alerter = Client().active_stack.alerter def notify_on_failure() -> None: """Notifies user on step failure. Used in Hook.""" step_context = get_step_context() if alerter and step_context.pipeline_run.config.extra["notify_on_failure"]: alerter.post(message=build_message(status="failed")) If the Al component is not present in Stack we suppress notification, but you can also dump it to the log as Error using: from zenml.client import Client from zenml.logger import get_logger from zenml import get_step_context logger = get_logger(__name__) alerter = Client().active_stack.alerter def notify_on_failure() -> None: """Notifies user on step failure.

It is quite easy to use. (You will need a valid OpenAI API key that has correctly set up billing for this.) Note that using this integration will incur charges on your OpenAI account. First, ensure that you have the OpenAI integration installed and have stored your API key within a ZenML secret: zenml integration install openai

igure the local Generic Azure resource client/SDK.Stack Components use The Azure Artifact Store Stack Component can be connected to a remote Azure blob storage container through an Azure Service Connector. The Azure Service Connector can also be used with any Orchestrator or Model Deployer stack component flavor that relies on a Kubernetes clusters to manage workloads. This allows AKS Kubernetes container workloads to be managed without the need to configure and maintain explicit Azure or Kubernetes kubectl configuration contexts and credentials in the target environment or in the Stack Component itself. Similarly, Container Registry Stack Components can be connected to a ACR Container Registry through an Azure Service Connector. This allows container images to be built and published to private ACR container registries without the need to configure explicit Azure credentials in the target environment or the Stack Component. End-to-end examples This is an example of an end-to-end workflow involving Service Connectors that uses a single multi-type Azure Service Connector to give access to multiple resources for multiple Stack Components. A complete ZenML Stack is registered composed of the following Stack Components, all connected through the same Service Connector: a Kubernetes Orchestrator connected to an AKS Kubernetes cluster a Azure Blob Storage Artifact Store connected to an Azure blob storage container an Azure Container Registry connected to an ACR container registry a local Image Builder As a last step, a simple pipeline is run on the resulting Stack. This example needs to use a remote ZenML Server that is reachable from Azure. Configure an Azure service principal with a client secret and give it permissions to access an Azure blob storage container, an AKS Kubernetes cluster and an ACR container registry. Also make sure you have the Azure ZenML integration installed:Copyzenml integration install -y azure

to your stack: zenml integration install wandb -yThe Weights & Biases Experiment Tracker needs to be configured with the credentials required to connect to the Weights & Biases platform using one of the available authentication methods. Authentication Methods You need to configure the following credentials for authentication to the Weights & Biases platform: api_key: Mandatory API key token of your Weights & Biases account. project_name: The name of the project where you're sending the new run. If the project is not specified, the run is put in an "Uncategorized" project. entity: An entity is a username or team name where you're sending runs. This entity must exist before you can send runs there, so make sure to create your account or team in the UI before starting to log runs. If you don't specify an entity, the run will be sent to your default entity, which is usually your username. This option configures the credentials for the Weights & Biases platform directly as stack component attributes. This is not recommended for production settings as the credentials won't be stored securely and will be clearly visible in the stack configuration. # Register the Weights & Biases experiment tracker zenml experiment-tracker register wandb_experiment_tracker --flavor=wandb \ --entity=<entity> --project_name=<project_name> --api_key=<key> # Register and set a stack with the new experiment tracker zenml stack register custom_stack -e wandb_experiment_tracker ... --set This method requires you to configure a ZenML secret to store the Weights & Biases tracking service credentials securely. You can create the secret using the zenml secret create command: zenml secret create wandb_secret \ --entity=<ENTITY> \ --project_name=<PROJECT_NAME> --api_key=<API_KEY> Once the secret is created, you can use it to configure the wandb Experiment Tracker: # Reference the entity, project and api-key in our experiment tracker component zenml experiment-tracker register wandb_tracker \ --flavor=wandb \

ne: while gc.collect(): torch.cuda.empty_cache()You can then call this function at the beginning of your GPU-enabled steps: from zenml import step @step def training_step(...): cleanup_memory() # train a model Note that resetting the memory cache will potentially affect others using the same GPU, so use this judiciously. Train across multiple GPUs ZenML supports training your models with multiple GPUs on a single node. This is useful if you have a large dataset and want to train your model in parallel. The most important thing that you'll have to handle is preventing multiple ZenML instances from being spawned as you split the work among multiple GPUs. In practice this will probably involve: creating a script / Python function that contains the logic of training your model (with the specification that this should run in parallel across multiple GPUs) calling that script / external function from within the step, possibly with some wrapper or helper code to dynamically configure or update the external script function We're aware that this is not the most elegant solution and we're at work to implement a better option with some inbuilt support for this task. If this is something you're struggling with and need support getting the step code working, please do connect with us on Slack and we'll do our best to help you out.

e following: Question: What are Plasma Phoenixes?Answer: Plasma Phoenixes are majestic creatures made of pure energy that soar above the chromatic canyons of Zenml World. They leave fiery trails behind them, painting the sky with dazzling displays of colors. Question: What kinds of creatures live on the prismatic shores of ZenML World? Answer: On the prismatic shores of ZenML World, you can find crystalline crabs scuttling and burrowing with their transparent exoskeletons, which refract light into a kaleidoscope of hues. Question: What is the capital of Panglossia? Answer: The capital of Panglossia is not mentioned in the provided context. The implementation above is by no means sophisticated or performant, but it's simple enough that you can see all the moving parts. Our tokenization process consists of splitting the text into individual words. The way we check for similarity between the question / query and the chunks of text is extremely naive and inefficient. The similarity between the query and the current chunk is calculated using the Jaccard similarity coefficient. This coefficient measures the similarity between two sets and is defined as the size of the intersection divided by the size of the union of the two sets. So we count the number of words that are common between the query and the chunk and divide it by the total number of unique words in both the query and the chunk. There are much better ways of measuring the similarity between two pieces of text, such as using embeddings or other more sophisticated techniques, but this example is kept simple for illustrative purposes. The rest of this guide will showcase a more performant and scalable way of performing the same task using ZenML. If you ever are unsure why we're doing something, feel free to return to this example for the high-level overview.

Develop a custom data validator How to develop a custom data validator Before diving into the specifics of this component type, it is beneficial to familiarize yourself with our general guide to writing custom component flavors in ZenML. This guide provides an essential understanding of ZenML's component flavor concepts. Base abstraction in progress! We are actively working on the base abstraction for the Data Validators, which will be available soon. As a result, their extension is not recommended at the moment. When you are selecting a data validator for your stack, you can use one of the existing flavors. If you need to implement your own Data Validator flavor, you can still do so, but keep in mind that you may have to refactor it when the base abstraction is updated. ZenML comes equipped with Data Validator implementations that integrate a variety of data logging and validation libraries, frameworks and platforms. However, if you need to use a different library or service as a backend for your ZenML Data Validator, you can extend ZenML to provide your own custom Data Validator implementation. Build your own custom data validator If you want to implement your own custom Data Validator, you can follow the following steps: Create a class which inherits from the BaseDataValidator class and override one or more of the abstract methods, depending on the capabilities of the underlying library/service that you want to integrate. If you need any configuration, you can create a class which inherits from the BaseDataValidatorConfig class. Bring both of these classes together by inheriting from the BaseDataValidatorFlavor. (Optional) You should also provide some standard steps that others can easily insert into their pipelines for instant access to data validation features. Once you are done with the implementation, you can register it through the CLI. Please ensure you point to the flavor class via dot notation:

Use pipeline/step parameters Steps and pipelines can be parameterized just like any other python function that you are familiar with. Parameters for your steps When calling a step in a pipeline, the inputs provided to the step function can either be an artifact or a parameter. An artifact represents the output of another step that was executed as part of the same pipeline and serves as a means to share data between steps. Parameters, on the other hand, are values provided explicitly when invoking a step. They are not dependent on the output of other steps and allow you to parameterize the behavior of your steps. In order to allow the configuration of your steps using a configuration file, only values that can be serialized to JSON using Pydantic can be passed as parameters. If you want to pass other non-JSON-serializable objects such as NumPy arrays to your steps, use External Artifacts instead. from zenml import step, pipeline @step def my_step(input_1: int, input_2: int) -> None: pass @pipeline def my_pipeline(): int_artifact = some_other_step() # We supply the value of `input_1` as an artifact and # `input_2` as a parameter my_step(input_1=int_artifact, input_2=42) # We could also call the step with two artifacts or two # parameters instead: # my_step(input_1=int_artifact, input_2=int_artifact) # my_step(input_1=1, input_2=2) Parameters of steps and pipelines can also be passed in using YAML configuration files. The following configuration file and Python code can work together and give you the flexibility to update configuration only in YAML file, once needed: # config.yaml # these are parameters of the pipeline parameters: environment: production steps: my_step: # these are parameters of the step `my_step` parameters: input_2: 42 from zenml import step, pipeline @step def my_step(input_1: int, input_2: int) -> None: ... # input `environment` will come from the configuration file, # and it is evaluated to `production`

This project must be the same as the one for which the external account was configured. If you already have the GOOGLE_APPLICATION_CREDENTIALS environment variable configured to point to an external account key JSON file, it will be automatically picked up when auto-configuration is used. The following assumes the following prerequisites are met, as covered in the GCP documentation on how to configure workload identity federation with AWS: the ZenML server is deployed in AWS in an EKS cluster (or any other AWS compute environment) the ZenML server EKS pods are associated with an AWS IAM role by means of an IAM OIDC provider, as covered in the AWS documentation on how to associate a IAM role with a service account. Alternatively, the IAM role associated with the EKS/EC2 nodes can be used instead. This AWS IAM role provides the implicit AWS IAM identity and credentials that will be used to authenticate to GCP services. a GCP workload identity pool and AWS provider are configured for the GCP project where the target resources are located, as covered in the GCP documentation on how to configure workload identity federation with AWS. a GCP service account is configured with permissions to access the target resources and granted the roles/iam.workloadIdentityUser role for the workload identity pool and AWS provider a GCP external account JSON file is generated for the GCP service account.

ant feedback of actual contact with the raw data.)Samples generated for inference: Your model will be making predictions on real-world data being passed in. If you store and label this data, you’ll gain a valuable set of data that you can use to compare your labels with what the model was predicting, another possible way to flag drifts of various kinds. This data can then (subject to privacy/user consent) be used in retraining or fine-tuning your model. Other ad hoc interventions: You will probably have some kind of process to identify bad labels, or to find the kinds of examples that your model finds really difficult to make correct predictions. For these, and for areas where you have clear class imbalances, you might want to do ad hoc annotation to supplement the raw materials your model has to learn from. ZenML currently offers standard steps that help you tackle the above use cases, but the stack component and abstraction will continue to be developed to make it easier to use. When to use it The annotator is an optional stack component in the ZenML Stack. We designed our abstraction to fit into the larger ML use cases, particularly the training and deployment parts of the lifecycle. The core parts of the annotation workflow include: using labels or annotations in your training steps in a seamless way handling the versioning of annotation data allow for the conversion of annotation data to and from custom formats handle annotator-specific tasks, for example, the generation of UI config files that Label Studio requires for the web annotation interface List of available annotators For production use cases, some more flavors can be found in specific integrations modules. In terms of annotators, ZenML features integrations with label_studio and pigeon.

Additionally, the connector can handle specialized authentication for S3, Docker and Kubernetes Python clients. It also allows for the configuration of local Docker and Kubernetes CLIs. The AWS Service Connector is part of the AWS ZenML integration. You can either install the entire integration or use a pypi extra to install it independently of the integration: pip install "zenml[connectors-aws]" installs only prerequisites for the AWS Service Connector Type zenml integration install aws installs the entire AWS ZenML integration It is not required to install and set up the AWS CLI on your local machine to use the AWS Service Connector to link Stack Components to AWS resources and services.

If left blank, Neptune will attempt to retrieve the token from your environment variables. project: The name of the project where you're sending the new run, in the form "workspace-name/project-name". If the project is not specified, Neptune will attempt to retrieve it from your environment variables. This option configures the credentials for neptune.ai directly as stack component attributes. This is not recommended for production settings as the credentials won't be stored securely and will be clearly visible in the stack configuration. # Register the Neptune experiment tracker zenml experiment-tracker register neptune_experiment_tracker --flavor=neptune \ --project=<project_name> --api_token=<token> # Register and set a stack with the new experiment tracker zenml stack register custom_stack -e neptune_experiment_tracker ... --set This method requires you to configure a ZenML secret to store the Neptune tracking service credentials securely.

Check out this page for more information on the hierarchy and precedence of the various ways in which you can supply the settings. Using a custom parent image By default, ZenML performs all the steps described above on top of the official ZenML image for the Python and ZenML version in the active Python environment. To have more control over the entire environment used to execute your pipelines, you can either specify a custom pre-built parent image or a Dockerfile that ZenML uses to build a parent image for you. If you're going to use a custom parent image (either pre-built or by specifying a Dockerfile), you need to make sure that it has Python, pip, and ZenML installed for it to work. If you need a starting point, you can take a look at the Dockerfile that ZenML uses here. Using a pre-built parent image To use a static parent image (e.g., with internal dependencies installed) that doesn't need to be rebuilt on every pipeline run, specify it in the Docker settings for your pipeline: docker_settings = DockerSettings(parent_image="my_registry.io/image_name:tag") @pipeline(settings={"docker": docker_settings}) def my_pipeline(...): ...

Reranking for better retrieval Add reranking to your RAG inference for better retrieval performance. Rerankers are a crucial component of retrieval systems that use LLMs. They help improve the quality of the retrieved documents by reordering them based on additional features or scores. In this section, we'll explore how to add a reranker to your RAG inference pipeline in ZenML. In previous sections, we set up the overall workflow, from data ingestion and preprocessing to embeddings generation and retrieval. We then set up some basic evaluation metrics to assess the performance of our retrieval system. A reranker is a way to squeeze a bit of extra performance out of the system by reordering the retrieved documents based on additional features or scores. As you can see, reranking is an optional addition we make to what we've already set up. It's not strictly necessary, but it can help improve the relevance and quality of the retrieved documents, which in turn can lead to better responses from the LLM. Let's dive in!

Promote a Model Stages and Promotion Model stages are a way to model the progress that different versions takes through various stages in its lifecycle. A ZenML Model version can be promoted to a different stage through the Dashboard, the ZenML CLI or code. This is a way to signify the progression of your model version through the ML lifecycle and are an extra layer of metadata to identify the state of a particular model version. Possible options for stages are: staging: This version is staged for production. production: This version is running in a production setting. latest: The latest version of the model. This is a virtual stage to retrieve the latest version only - versions cannot be promoted to latest. archived: This is archived and no longer relevant. This stage occurs when a model moves out of any other stage. Your own particular business or use case logic will determine which model version you choose to promote, and you can do this in the following ways: Promotion via CLI This is probably the least common way that you'll use, but it's still possible and perhaps might be useful for some use cases or within a CI system, for example. You simply use the following CLI subcommand: zenml model version update iris_logistic_regression --stage=... Promotion via Cloud Dashboard This feature is not yet available, but soon you will be able to promote your model versions directly from the ZenML Cloud dashboard. Promotion via Python SDK This is the most common way that you'll use to promote your models. You can see how you would do this here: from zenml import Model MODEL_NAME = "iris_logistic_regression" from zenml.enums import ModelStages model = Model(name=MODEL_NAME, version="1.2.3") model.set_stage(stage=ModelStages.PRODUCTION) # get latest model and set it as Staging # (if there is current Staging version it will get Archived) latest_model = Model(name=MODEL_NAME, version=ModelStages.LATEST) latest_model.set_stage(stage=ModelStages.STAGING)

In addition to built-in Service Connector Types, ZenML can be easily extended with custom Service Connector implementations.\n\nTo discover the Connector Types available with your ZenML deployment, you can use the zenml service-connector list-types CLI command:\n\nzenml service-connector list-types\n\nExample Command Output\n\n\u250f\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u252f\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u252f\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u252f\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u252f\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u252f\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2513\n\n\u2503             NAME             \u2502 TYPE          \u2502 RESOURCE TYPES        \u2502 AUTH METHODS      \u2502 LOCAL \u2502 REMOTE \u2503\n\n\u2520\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2528\n\n\u2503 Kubernetes Service Connector \u2502 \ud83c\udf00 kubernetes \u2502 \ud83c\udf00 kubernetes-cluster \u2502 password          \u2502 \u2705    \u2502 \u2705     \u2503\n\n\u2503                              \u2502               \u2502                       \u2502 token             \u2502       \u2502        \u2503\n\n\u2520\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2528\n\n\u2503   Docker Service Connector   \u2502 \ud83d\udc33 docker     \u2502 \ud83d\udc33 docker-registry    \u2502 password          \u2502 \u2705    \u2502 \u2705     \u2503\n\n\u2520\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2528\n\n\u2503   Azure Service Connector    \u2502 \ud83c\udde6 azure      \u2502 \ud83c\udde6 azure-generic      \u2502 implicit          \u2502 \u2705    \u2502 \u2705     \u2503\n\n\u2503                              \u2502               \u2502 \ud83d\udce6 blob-container     \u2502 service-principal \u2502       \u2502        \u2503",
