[Bug Report] BabyAI not working

[Valaybundele]

Hi, I am trying to install BabyAI on Linux 64-bit system. I followed the instructions mentioned in the BabyAI repo for installing the environment. The BabyAI environment file specifies Python 3.6 as the dependency while the latest version of gym-minigrid is incompatible with that. So, I modified it to Python 3.7.3 and then ran the following code.

git clone https://github.com/mila-iqia/babyai.git cd babyai conda env create -f environment.yaml source activate babyai

cd .. git clone https://github.com/maximecb/gym-minigrid.git cd gym-minigrid pip install --editable .

cd ../babyai pip install --editable .

Although, I was able to successfully run this code and install the dependencies, I am getting this error when I am trying to import babyai.

Can something be done here or can I find the older repo somewhere since the latest version doesn't seem to work with BabyAI?

Thanks

Thanks for the issue, I have contacted one of the devs for BabyAI and they are going to make a release to fix this. Uncertain of the timeline for the fix but they are aware

Hi @pseudo-rnd-thoughts,

Thanks for the quick reply. I understand that it might take time and so I was just wondering if I could get the older version of gym-minigrid repo somewhere so that I could continue with my experimentation. Please let me know if this is possible.

Thanks

The easiest way is to probably clone this repo, and add to the envs/__init__.py to import from gym_minigrid.minigrid import Ball, Key, Box and this should work now

Hi @pseudo-rnd-thoughts, Thanks for the quick fix. I added the line from gym_minigrid.minigrid import Ball, Key, Box in babyai/babyai/levels/bonus_levels.py and I was able to import babyai successfully. But now when I am trying to make a new BabyAI environment, I am getting this error:

import babyai from gym_minigrid.wrappers import RGBImgPartialObsWrapper, ImgObsWrapper env = gym.make('BabyAI-GoToLocal-v0') Traceback (most recent call last): File "", line 1, in File "/home/biplab/anaconda3/envs/babyai/lib/python3.7/site-packages/gym/envs/registration.py", line 674, in make raise e File "/home/biplab/anaconda3/envs/babyai/lib/python3.7/site-packages/gym/envs/registration.py", line 662, in make env = env_creator(_kwargs) File "/home/biplab/Valay/babyai/babyai/levels/iclr19_levels.py", line 116, in init seed=seed File "/home/biplab/Valay/babyai/babyai/levels/levelgen.py", line 32, in init kwargs File "/home/biplab/anaconda3/envs/babyai/lib/python3.7/site-packages/gym_minigrid/roomgrid.py", line 96, in init **kwargs, TypeError: init() missing 1 required positional argument: 'mission_space'

I also tried adding mission_space='GoToLocal' in anaconda3/envs/babyai/lib/python3.7/site-packages/gym_minigrid/roomgrid.py" but I am still getting this error :

env = gym.make('BabyAI-GoToLocal-v0') Traceback (most recent call last): File "", line 1, in File "/home/biplab/anaconda3/envs/babyai/lib/python3.7/site-packages/gym/envs/registration.py", line 674, in make raise e File "/home/biplab/anaconda3/envs/babyai/lib/python3.7/site-packages/gym/envs/registration.py", line 662, in make env = env_creator(_kwargs) File "/home/biplab/Valay/babyai/babyai/levels/iclr19_levels.py", line 116, in init seed=seed File "/home/biplab/Valay/babyai/babyai/levels/levelgen.py", line 32, in init kwargs File "/home/biplab/anaconda3/envs/babyai/lib/python3.7/site-packages/gym_minigrid/roomgrid.py", line 96, in init mission_space='GoToLocal', TypeError: init() missing 1 required positional argument: 'mission_space'

Could you please suggest something to resolve this issue?

Thanks

I have downgrade the minigrid version, and hopefully babyAI will be fixed soon pip uninstall gym-minigrid then pip install gym-minigrid==1.0.3

[Valaybundele]

Hi, Thanks for downgrading the version. So these are the instructions to install BabyAI given in the repo:

git clone https://github.com/mila-iqia/babyai.git cd babyai conda env create -f environment.yaml source activate babyai

cd .. git clone https://github.com/maximecb/gym-minigrid.git cd gym-minigrid pip install --editable .

cd ../babyai pip install --editable .

Since gym-minigrid repo has been updated, I didn't clone it and created a new environment and ran the following code :

git clone https://github.com/mila-iqia/babyai.git cd babyai conda env create -f environment.yaml source activate babyai

pip install gym-minigrid==1.0.3

So now I am able to load the BabyAI environment but when I tried to reset the environment, I got the following error: Python 3.6.13 |Anaconda, Inc.| (default, Jun 4 2021, 14:25:59) [GCC 7.5.0] on linux Type "help", "copyright", "credits" or "license" for more information.

Is this because gym-minigrid repo has been updated and I didn't install it by cloning the repo or is the issue something else?

Thanks

Hopefully all of these issues will be fixed by BabyAI soon, but in the meantime, you can use env = gym.make('BabyAI-GoToRedBall-v0', disable_env_checker=True) which should fix your issue

Hi,

That worked. Thanks a lot for the help!
