Jina is a cloud-native project, and provides long-term support from afull-time, venture-backed team.⏱️Time Saver- Bootstrap an AI-powered system in just a few minutes withcookiecutter.🧠First-Class AI models- Jina is a new design pattern for neural search systems with first-class support forstate-of-the-art AI modelslike Faiss, Annoy, Onnx, and more.🌌Universal Search- Large-scale indexing and querying data of any kind on multiple platforms. Video, image, long/short text, music, source code, and more.🚀Production Ready- Cloud-native features out-of-the-box, like containerization, microservice, distributing, scaling, sharding, async IO, REST, gRPC.🧩Plug & Play- WithJina Hub, you can extend Jina with simple Python scripts or Docker images optimized for your search domain.ContentsGet StartedJina "Hello, World!" 👋🌍TutorialsDocumentationContributingCommunityOpen GovernanceJoin UsLicenseGet StartedFrom PyPiOn Linux/MacOS with Python >= 3.7:pipinstalljinaTo install Jina with extra dependencies, or install on Raspberry Piplease refer to the documentation.With Cookiecutterpipinstallcookiecutter&&cookiecuttergh:jina-ai/cookiecutter-jinaWithCookiecutteryou can easily create a Jina project from templates with one terminal command. This creates a Python entrypoint, YAML configs and a Dockerfile. You can start from there.In a Docker ContainerWe provide a universal Docker image that supports multiple architectures (including x64, x86, arm-64/v7/v6). Simply run:dockerrunjinaai/jina--helpJina "Hello, World!" 👋🌍As a starter, you can try out our "Hello, World" - a simple demo of image neural search forFashion-MNIST. No extra dependencies needed, just run:jinahello-world...or even easier for Docker users,no install required:dockerrun-v"$(pwd)/j:/j"jinaai/jinahello-world--workdir/j&&openj/hello-world.html# replace "open" with "xdg-open" on LinuxClick here to see console outputThe Docker image downloads the Fashion-MNIST training and test dataset and tells Jina to index 60,000 images from the training set. Then it randomly samples images from the test set as queries and asks Jina to retrieve relevant results. The whole process takes about 1 minute, and eventually opens a webpage and shows results like this:The implementation behind it is simple:Python APIor useYAML specor useDashboardfromjina.flowimportFlowf=(Flow().add(uses='encoder.yml',parallel=2).add(uses='indexer.yml',shards=2,separated_workspace=True))withf:f.index(fashion_mnist,batch_size=1024)!Flowpods:encode:uses:encoder.ymlparallel:2index:uses:indexer.ymlshards:2separated_workspace:trueExplore sharding, containerization, concatenating embeddings, and moreAdding Parallelism and Shardingfromjina.flowimportFlowf=(Flow().add(uses='encoder.yml',parallel=2).add(uses='indexer.yml',shards=2,separated_workspace=True))Distributing the Flowfromjina.flowimportFlowf=Flow().add(uses='encoder.yml',host='192.168.0.99')Using a Docker Containerfromjina.flowimportFlowf=(Flow().add(uses='jinahub/cnn-encode:0.1').add(uses='jinahub/faiss-index:0.2',host='192.168.0.99'))Concatenating Embeddingsfromjina.flowimportFlowf=(Flow().add(name='eb1',uses='BiTImageEncoder').add(name='eb2',uses='KerasImageEncoder',needs='gateway').needs(['eb1','eb2'],uses='_concat'))Enabling Network Queriesfromjina.flowimportFlowf=Flow(port_expose=45678,rest_api=True)withf:f.block()Intrigued?
