Running Pendulum with some other algorithm or running PPO with some other environment seems to work. I can't really see where the problem is but thought you would like to know something is amiss.

A = action_space(inner_env)

I guess it's just a name confliction.

Not sure why this experiment is not added in tests. PR is welcomed😀

Okay, went and did that. Closing this, see #165 for more info.
