Cannot import mujoco_py into python

Hi

I installed mujoco_py and downloaded mjpro131 64bit.
When I try to import mujoco_py, I see this error:

Code:

Can someone tell me what's the problem? Apparently it's a common problem that shows up when importing C++ libraries into python code and you should recompile the library to fix the problem.
