AttributeError: 'CoinRunVecEnv' object has no attribute 'spec'

Hi openai team

I am trying to setup the coinrun.

I have followed the installation instructions in the readme.md and had no problem.

However when i try to run training, e.g. python -m coinrun.train_agent --run-id myrun --num-levels 500

i get the this error: AttributeError: 'CoinRunVecEnv' object has no attribute 'spec'

hi, while u wait for any of the contributors to reply, u can try gym==0.10.0. I am pretty sure the problem is due to the version of the library.

[TylerJamesMalloy]

I had the same issue and switching to gym==0.10.0 worked for me.

[christopherhesse]

Should requirements.txt use a more restrictive gym version? https://github.com/openai/coinrun/blob/master/requirements.txt#L2

Maybe it should be gym==0.10.0
