error about ai2thor-xorg

Hello, I am a beginner in ai2thor.when i use google colab, linux remote server and local laptop to run example code, it raise the same error:

> Exception Traceback (most recent call last)

> Linux64 requires a X11 server to be running with GLX. If you have a NVIDIA GPU, please run: sudo ai2thor-xorg start

how can i fix this issue? i need to run this python file (also your work)[https://github.com/allenai/interactron/blob/main/data_collection/collect_ithor_tree_data.py](url) to generate my dataset, but i can't fix this error.

I would be greatly appreciative if you could respond to me.
