Does anyone have any solutions to the following GLFW and GLX error? I did the usual Google searching but haven't solved it yet.

(stylegan3) $ python visualizer.py
/home/me/anaconda3/envs/stylegan3/lib/python3.9/site-packages/glfw/__init__.py:906: GLFWError: (65542) b'GLX: GLX extension not found'
  warnings.warn(message, GLFWError)
python: /builds/florianrhiem/pyGLFW/glfw-3.3.5/src/input.c:835: glfwSetKeyCallback: Assertion `window != ((void *)0)' failed.
Aborted (core dumped)
