Hello, Thank you so much for reading this post! I am running mujoco200 on Ubuntu 18.04 and my python version is 3.7.3. I have already successfully opened the mujoco GUI using 'simulate' in the terminal. However, when I want to render an environment in a python file with mujoco-py, it will show there is no reply and keep loading all the time Does anyone know the reason for this problem? I would be very appreciated!
