Hi @araffin. Thanks for the great repo. I'm trying to train everything from scratch based on your work.

I collected images using the teleoperation mode and starting to train the VAE but the following error come up when I tried to run python3 -m vae.train --n-epochs 50 --verbose 0 --z-size 64 -f ./data/vae/

Traceback (most recent call last):

    "__main__", mod_spec)

Everything is up-to-date with the latest code on master. I installed all the dependencies with pip3 install -r requirement.txt. Also, my system don't have any virtual environment or anaconda. I tried to reinstall gym a couple time via pip but it still not working.

Any ideals how to solve this problem ? Thanks a lot.

Hello, this error is due to open ai breaking gym api. Two solutions:

EDIT: the branch is now merged with master branch of stable-baselines

lamhoangtung commented 5 years ago

Thanks @araffin for the quick reply. I installed stable-baselines from master branch and everything is working great now. I put this command here just in case anyone needed it ;)

pip3 install git+https://github.com/hill-a/stable-baselines

Perfect.

Note: the command is already in the doc ;)
