Installation fail

[MFaisalZaki]

Hi I am trying the basic tutorial for plangym:

import plangym

env = plangym.make(name="ALE/RoadRunner-ram-v5")
state, obs, info = env.reset()

state = state.copy()
action = env.action_space.sample()

data = env.step(state=state, action=action)
new_state, observ, reward, end, truncated, info = data

And I am getting this error:

File "temp-venv/venv/lib/python3.12/site-packages/gymnasium/envs/registration.py", line 350, in _check_namespace_exists
    raise error.NamespaceNotFound(f"Namespace {ns} not found. {suggestion_msg}")
gymnasium.error.NamespaceNotFound: Namespace ALE not found. Have you installed the proper package for ALE?

This is probably due to not having the Atari roms available in your environment.

Can you try installing all the extra dependencies with pip install -r requirements.lock? This file contains a list of all the dependencies needed to run all the environments.

If you are only interested in running Atari games, you could also take a look at the extra dependencies and run pip install plangym[nes]

I will try to improve the intallation tutorials over the weekend.
