Questions of reward every step output

[POJIANWU]

Hi,I'm interested in your project,but I'm confused about your warehouse.py,that is,why does't it output reward values every time step?Longing for your reply!

It should give you rewards at every time step (at a typical gym-interface fashion).

Do note that this is a (somewhat) sparse-reward environment. Non-zero rewards are given only upon successfully delivering a requested shelf.

Thanks for your reply!Another question that is when I run the test_obs_space_2 in test_env.py,I meet this error"assert len(gym.spaces.flatten(s, o)) == env._obs_length E assert 133 == 116".What should I do?Hope for your soon reply!
