Hi , I'm new to this project, when I entering run_this folder and try to run the project, I got this error

The run_object.py runs correctly without any errors on my PC. Have you set up all the environment for the python project? Or have you changed the variables of the DRL environment?

在我机器上跑是没问题的，Python相关的库你装全了吗，或者有没有改过深度强化学习的环境参数？

This error appeared to me when I switch to another PC, currently have no solution, but I guess this error connects to the NumPy module.

Thank you for providing code! But I can't find the paper. Maybe the paper is checking. But I want to have a look to develop my find. Can you give me a link about the paper? Thanks a lot again.
