What's the package version of gym-minigrid and gym used for the baseline results?

Hi. It seems that the gym and gym-minigrid versions are not specified in the repo. I tried gym-minigrid==1.0.2 and gym==0.24.1, and it gives the following error when I run scripts/train_rl.py --env BabyAI-GoToLocal-v0:

Traceback (most recent call last):

AssertionError: The observation returned by the `reset()` method is not contained with the observation space (Dict(image: Box(0, 255, (7, 7, 3), uint8)))

I somehow fixed this by downgrading gym to 0.10.9, but I wonder if the versions of gym and gym-minigrid may affect the environment. Also, the latest version of gym-minigrid no longer supports python 3.6, which was specified in environment.yaml. So can you specify the gym and gym-minigrid versions you used for producing your results? Thanks a lot!

Please use minigrid (which includes BabyAI environments) and torch-ac, instead of this repo.

Hi there, the version of gym minigrid I used was af0e00fe906fccfc70ef116a5ee89751e1441942 and the BabyAI version was 863f3529371ba45ef0148a48b48f5ae6e61e06cc
