feat: running `ng_run` outside of the gym repository

I'd like to use Gym as a dependency in a project and I've therefore installed NeMo-RL (containing Gym) as a submodule of my project. Then in my project I have created a gym folder containing my custom resources servers and responses api agents.

Basically here is what my gym folder looks like

OwkinZero/agentic/gym
├── README.md
├── create_symlinks.sh
├── resources_servers
│   └── llm_judge_reward
│       ├── README.md
│       ├── app.py
│       ├── configs
│       └── requirements.txt
├── responses_api_agents
│   └── idea_generator_agent
│       ├── README.md
│       ├── __init__.py
│       ├── app.py
│       ├── client.py
│       ├── configs
│       ├── data
│       ├── outputs
│       └── requirements.txt
└── scripts
    └── submit_training.sh

I tried to run the ng_run command from my working directory (called OwkinZero/agentic). First, in order to have access to the command I installed nemo_gym in editable mode. Then I encountered a first issue: the env variables defined in my env.yaml file (located at the root of OwkinZero/agentic) were not loaded. I had to add the file to the config_paths list.

So here is the commands I run

config_paths="/fsx/xav/code/OwkinZero/agentic/env.yaml,/fsx/xav/code/OwkinZero/agentic/gym/responses_api_agents/idea_generator_agent/configs/idea_generator_agent.yaml,/fsx/xav/code/OwkinZero/agentic/gym/resources_servers/llm_judge_reward/configs/llm_judge_reward.yaml,/fsx/xav/code/OwkinZero/agentic/gym/responses_api_agents/idea_generator_agent/configs/gpt_5_nano.yaml"

ng_run "+config_paths=[${config_paths}]"

And here is the error that I get

Note the /fsx/xav/code/OwkinZero/agentic/.venv/lib/python3.12/site-packages/responses_api_agents/idea_generator_agent actually does not exist.

The only workaround that I found was to create symbolic links from my custom resource servers and resource api agents to the corresponding folder in the Gym repo and to run ng_run from Gym but that's not very convenient.

Is there a way to run ng_run from my project root or am I forced to put new resource servers in the Gym directory?
