Gym: AttributeError: 'TimeLimit' object has no attribute 'x_threshold'

Created on 19 Mar 2017 · 2Comments · Source: openai/gym

Thanks for your great work.

I had gym 0.7.3 installed before and I can use the env attributes like "x_threashold" in Cartpole.
But now, in gym 0.7.4 and higher, I cannot use those anymore.

Also, in MountainCar, LunnarLander and possibly more, the episode seems to be limited to some time range. Hope that be fixed soon.

If you're trying to munge attributes of the environment (which renders your learning results not comparable with anyone else's) you can get at the raw environment with env.unwrapped, as in env.unwrapped.x_threshold = -1

The episode is indeed limited to a time range, by design. An environment with unlimited time isn't as challenging to solve.
