Model (keras) error about assistive-gym HOT 5 CLOSED

Hi Zhihao,

Here is a requirements.txt file with all of the Python libraries needed for a clean install of Assistive Gym.

Thanks!!
I updated keras to 2.3.1 and solved this problem.
However, after I run the random-actions.py in the examples, here are still errors:

It looks like you may have the original pybullet library installed.
You will want to install a customized pybullet here: https://github.com/Zackory/bullet3
Further details can be found here: https://github.com/Healthcare-Robotics/assistive-gym/wiki/1.-Install

This custom pybullet library includes python wrappers for cloth simulation and human joint limits in pybullet.

Thanks!! It works now!
I think this issue (question) can be closed now and hope it would also be helpful for other beginners.
BTW, you and your team's work are so impressive! It is definitely a valuable project for deploying reinforcement learning with python bullet. I also visited your personal website and your experience and works are so brilliant! I will learn from you. : )
