reset agent but not the envirnment about cups-rl HOT 3 OPEN

I tried to use teleport to reset agent's position without affecting environment:
env.step(action='Teleport', x=0.999, y=1.01, z=-0.3541)

but got error:TypeError: step() got an unexpected keyword argument 'x'
So apparently 'env' is not the same as 'controller' in ai2thor. I'm not sure how to use controller.step(action='Teleport', x=0.999, y=1.01, z=-0.3541) in your implementation. Mind to give any advice?

Thanks.

It occurred to me that the current wrapper does not permit teleport. Then is there any way to save the environment setting (everything apart from the agent) and load it later?

from cups-rl.

also when I choose not to reset the environment by commenting both line 141 and 157 it gives me this error:
AttributeError: 'NoneType' object has no attribute 'metadata'

when it ran line 132:
next_state, _, done = env.step(np.random.randint(0, action_space))

Does this line just let agent make a random movement and what could be the possible reasons for the error?
