Hello,

I am having an issue with the multiple crypto env. Anybody's help would be appreciated. Thanks!

Got connected bug when tried run CryptoEnv with rllib from tutorial:

File "/home/usr0/venvpy38/lib/python3.8/site-packages/ray/rllib/evaluation/rollout_worker.py", line 1698, in _validate_env
   if not env.observation_space.contains(dummy_obs):
AttributeError: 'NoneType' object has no attribute 'contains'
