Can not step

[xiaoyuanzh]

If I use your env
env = utils.NormalizedActions(gym.make(env_tag))
I can not step an action, it says not implement error,

If I use your env env = utils.NormalizedActions(gym.make(env_tag)) I can not step an action, it says not implement error,

I met the same problems. Have you solved this question?

[zhengluohu]

if your error is 'raise NotImplementedError', you can solved it by install an older verision of gym(gym==0.15.6) or use the step (core. mod_utils.py) instead of _step.

class NormalizedActions(gym.ActionWrapper):

def _action(self, action):
    action = (action + 1) / 2  # [-1, 1] => [0, 1]
    action *= (self.action_space.high - self.action_space.low)
    action += self.action_space.low
    return action

def _reverse_action(self, action):
    action -= self.action_space.low
    action /= (self.action_space.high - self.action_space.low)
    action = action * 2 - 1
    return action

When I run in Pendulum-v0, I get "RuntimeError: CUDA error: CUBLAS_STATUS_EXECUTION_FAILED when calling 'cublasSgemm' unless I set batch_size to 16. Why is that? My python environment is set to the same environment as yours.
