When I run cartpole_server.py as described in the module comments I receive the error:
Traceback (most recent call last): File "cartpole_server.py", line 156, in <module> get_trainable_cls(args.run).get_default_config() AttributeError: 'dict' object has no attribute 'environment'
It seems that this method is returning a legacy environment dict, rather than some new object that is supposedly expected.
What can I do to get this up and running?
edit: I am using: ray 2.1.0, rllib 3.2.0, python 3.8.5
