GLFW error in SSH server #879

Closed AntonioSerrano closed 4 years ago

AntonioSerrano commented 6 years ago

I am trying to run Open AI Gym with MuJoCo 1.31 in a server via -X -Y ssh. The machine has Ubuntu 16.04 and CUDA 8 installed and goes with a Nvidia Titan. However, I got the following error related to OpenGL/Mesa. In particular, with the GLFW library:

GLFW error: 65537, desc: b'The GLFW library is not initialized'

Any clue? Thx.

This sounds similar to https://github.com/openai/gym/issues/366 does running an OpenGL accelerated X server fix the issue?

On the ssh client terminal use fake screen to remove the glfw error.

$ xvfb-run -a -s "-screen 0 1400x900x24" python dmc_test.py

dmc_test.py uses mujoco environment and hence throws up GLFW initialization error when accessed through SSH. The above command solves this error.

if the package xvfb is not installed, use the following command to install: sudo apt install xvfb
