Describe the bug i installed keras_rl with tensorflow1.15, python 3.7.7, mujoco_py1.50.0.1, i had tried both mjppro150 and mjppro200 which ./simulate ../model/humanoid.xml can be executed successfully. but when i test python ddpg_mujoco.py, it shows that problem To Reproduce Steps to reproduce the behavior.
