Dict object has no attribute Env_Specs

[aaravnavani]

Hello,

I was properly able to get the conda enviornment to work and the necessary libraries installed, but I get this error when I run the training command that is in the README file:

File "train.py", line 318, in <module>
    main()
  File "train.py", line 200, in main
    frame_skip=args.action_repeat
  File "/home/anavani/anaconda3/envs/rad/lib/python3.7/site-packages/dmc2gym/__init__.py", line 28, in make
    if not env_id in gym.envs.registry.env_specs:
AttributeError: 'dict' object has no attribute 'env_specs'

I'm not sure why this is, so I would really appreciate it if anyone could take a look and let me know whats wrong. @MishaLaskin
