A problem about the wrappers

[shinshiner]

Hello, I am very interested in this repo and I want to reproduct the result. However, when I run the train.py in child mode(I am not familiar with tmux), it report an error that

Traceback (most recent call last):
  File "worker.py", line 188, in <module>
    tf.app.run()

AttributeError: module 'gym.spaces.multi_discrete' has no attribute 'DiscreteToMultiDiscrete'

It seems that the environment encounts some problems, have you met this error ? I can use gym.spaces.multi_discrete.DiscreteToMultiDiscrete in my other python script. Do you have some ideas about this issue ?

This is gym version issue. But if you follow the instructions in ReadMe exactly, it should not come. Seems like you installed gym separately manually.

OK, I tried the whole process again and now I can successfully run the training code, thank you very much !
