import rware import gym

env = gym.make("rware-tiny-2ag-v1")

When I run the above code I get an error: env = gym.make("rware-tiny-2ag-v1") File "D:\anconda_env\envs\robotic_warehouse\lib\site-packages\gym\envs\registration.py", line 640, in make env = env_creator(**_kwargs) File "D:\anconda_env\envs\robotic_warehouse\lib\site-packages\rware\warehouse.py", line 247, in init self._use_slow_obs() File "D:\anconda_env\envs\robotic_warehouse\lib\site-packages\rware\warehouse.py", line 359, in _use_slowobs for in range(self.n_agents) File "D:\anconda_env\envs\roboticwarehouse\lib\site-packages\rware\warehouse.py", line 359, in for in range(self.n_agents) File "D:\anconda_env\envs\robotic_warehouse\lib\site-packages\gym\spaces\multi_binary.py", line 44, in init assert (np.asarray(input_n) > 0).all() # n (counts) have to be positive AssertionError The picture above is the package of my environment
