Error during environment installatin

[lyshuga]

Hi, thank you for releasing your code.

I was trying to test your code with checkpoints. But there was aproblem occured during the installation of the env. I tried both docker and "conda create env", though the problem is the same. So, the installation takes up to 15-20 mins and after that it fails with error like this:

I was wondering if you also had issues like this?

Hi @lyshuga, thanks for your interest. According to https://github.com/openai/gym/issues/3176 this seems to be a recent issue with the gym package dependencies. I will see if I can update the installation instructions to accommodate this change. In the mean time, you should be able to resolve the issue by following the suggestions in the gym issue.

Hi again,

I have updated environment.yaml to use the specific package versions suggested by https://github.com/openai/gym/issues/3176, and verified that the installation now succeeds.

I'll close this issue, but please feel free to re-open if you have any additional questions!
