set maxlen based on stage and obey max_seq_length settings
State: closed | Pull request: yes
Labels: name: stale

name: NLP

# What does this PR do ?

memory/tokens for generation is pre-assigned with size `min(context_lenght + tokens_to_generate, max_seq_length)`

This causes a crash if `context_length + tokens_to_generate` > `max_seq_length` because the clipping strategy was not doing any clipping of the maxlen.

This PR adds the clipping strategy for models that don't use learned position embeddings.

[DO NOT MERGE] Prototype to show LLM with ModelPT as Base Class
State: closed | Pull request: yes
Labels: name: core

name: stale

name: NLP

# What does this PR do ?

Prototype code to try using ModelPT as base class for LLM. Enables path to backward compatibility with NeMo 1.x mcore models.

**Collection**: [LLM]

# Changelog 
- [NOTE] For simplicity, the LLMSaveRestoreConnector is duplicated. It will me moved out of final version

# Usage

There are two scripts in `examples/temp/` which show how to load a new model and train it on dummy data and use modelpt functions in it, and other is to restore that model fully with modelpt API.

A third script is available which loads a NeMo 1.x mcore llm model and uses the 2.x class to instantiate it and do inference on it.

# Dependency

- Mcore requires update to its data class to make it yaml serializable with OmegaConf

Use ModelOpt build_tensorrt_llm for building engines for qnemo checkpoints
State: closed | Pull request: yes

# What does this PR do ?

Use ModelOpt's `build_tensorrt_llm` utility for accuracy and performance alignment for engines build.

This introduces modelopt as an extra dependency in `nemo.export` module and it is a temporal solution. In long term engines for qnemo should be built directly using tensorrt_llm.

Job specific environment variables can't be set in Hydra multi-run
State: closed | Pull request: no
Labels: name: stale

**Is your feature request related to a problem? Please describe.**

Hydra offers a way to set the environment variables, that are specific for each job - section hydra.job.env_set [here](https://hydra.cc/docs/1.0/configure_hydra/job/#hydrajobenv_set). However, when I added this to the configuration for my multi-run hyperparameter search, the environment variable was not changed. I suspect that the reason for that is that NeMo has a custom [launcher](https://github.com/NVIDIA/NeMo/blob/main/nemo/core/utils/process_launcher/launcher.py), through which hydra executes the job. I did not find that these environment variables would be handled anywhere in there.

**Describe the solution you'd like**

I would like to be able to set job-specific environment variables in the same way that Hydra documentation describes it. This means I should be able to add field job.env_set in Hydra config for multi-runs (screenshot below).

![Screenshot 2024-06-12 at 10 20 03](https://github.com/NVIDIA/NeMo/assets/56541137/cde4b394-fc57-4dcf-b2b7-78f7791557b6)


**Describe alternatives you've considered**

The only alternative that I found so far and that works is to manually set the environment variables inside the training script (each job is a training script). However, inside these scripts, I don't have access to the job ID, and hence, I had to infer it from the values of hyperparameters. This is far from ideal, and it would be much nicer to have a config-level solution.

**Additional context**

The main reason that I went into trouble with the environment variables is a problem with ports when training multiple models at once. The process is initialized on the master port, and consequently, the following error happens:

`torch.distributed.DistNetworkError: The server socket has failed to listen on any local network address. The server socket has failed to bind to [::]:53394 (errno: 98 - Address already in use). The server socket has failed to bind to 0.0.0.0:53394 (errno: 98 - Address already in use).`

The solution to avoid this error is to set the environment variable MASTER_PORT to a different value for each job. Without this option, running multiple training processes in parallel is impossible due to port collisions.


We don't use process launcher unless you use hydra sweep config. Can you try removing that ? If not, we'll have to see how to implement your request. Ofc, if you have a solution you're encouraged to send a pr 

Is there a way to perform a hyperparameter search without the hydra sweep?
