While I am running the local_example.py, the error comes out like:

I don't know how to deal with it. I have already created an new envs and installed depends. But it comes out. It looks like there's something wrong with the program.

Try examples written in DDPG class of python_motion_planning/local_planner/ddpg.py (line 216 to 230).

Thank you very much. Now the algorithm works.
