Do you solve the problem? When I run bash demo_tasks.sh all, I met the same problem

[scotthuang1989]

I think this is a compatibility issues. As I recall older version of gym use

_step

, but new one requires

step

this is why gym.make will fail at this line:

observation, _reward, done, _info = self.step(np.zeros(self.model.nu))

I don't if owner of this repo have plan to maitain this.
