Regressions from gym and tensorflow

[Jaeyoung-Lim]

This package no longer works with the latest openai/gym(v0.15.4) and tensorflow (v2.0.0)

Error from the latest gym environment:

Traceback (most recent call last):
  File "/usr/lib/python3.6/runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)

    from gym.wrappers import FlattenDictWrapper
ImportError: cannot import name 'FlattenDictWrapper'

It is a shame that the CI was not able to catch this

Looks like the following combination of versions work:

• gym: v1.12.1
• tensorflow-gpu: v1.15
