Failed building wheel for mujoco-py with OpenAI Gym

Question

I followed the installation instructions for OpenAI Gym, but the full install gives the error "Failed to build wheel for mujoco-py"

pip install gym and import gym work fine on my laptop and import mujoco_py works too, but I'm still getting a "failed to build wheel error"

If someone could explain why I am getting this invalid syntax error it would be useful.

MuJoCo is a physics engine for detailed, efficient rigid body simulations with contacts. mujoco-py allows using MuJoCo from Python 3.

Python 2 has been desupported since 1.50.1.0. Python 2 users can stay on the 0.5 branch. The latest release there is 0.5.7 which can be installed with pip install mujoco-py==0.5.7.

I got stuck on same issue after box2d installation.
Solved by hit and trial of different versions installation of mujoco.
My working versions are listed below
Python 2.7.14
gym 0.12.1
mujoco-py=0.5.7

Hope this helps.

Mujoco supports only python3 now. I had a similar problem because I had both python2 and python3 installed. Removing python2 and keeping only python3 solved the issue.

Use this:

sudo apt purge python2.7-minimal

I got some similar issue for a couple of days with installing mujoco-py using command :`pip3 install -U 'mujoco-py<1.50.2,>=1.50.1' while i had already installed version 2 of mujoco too. system failed on building wheel for mujoco-py. i knew i should change the directory command in .bashrc related to mujoco210 and make a new one for mjpro150 but still i kept getting similar error. then i figured i should have closed all terminals and then change bashrc and source it and then again attempt to install mujoco-py. cause first terminal was open (that one related to installation) and i opened another terminal for sourcing .bashrc so the first terminal didn't consider the changing in bashrc untill i closed and open a new one for installation.

That is really not how bash or bashrc is working. – chrslg Nov 08 '22 at 21:37 — chrslg, Nov 08 '22 at 21:37
