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)

Exception: The following builds were found, but had missing dependencies. Only one valid platform is required to run AI2-THOR.
Platform Linux64 failed validation with the following errors: Invalid display: :1. Failed to connect Can't connect to display ":1": [Errno 111] Connection refused
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 to generate my dataset, but i can't fix this error.

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

Same problem here, have you solved this problem? Thanks very much!

After deploying and running the ai2thor code on a cloud server, I encountered this issue. Since ai2thor is based on Unity, it requires the X11 server to be available on the GPU. However, since cloud servers do not have a display interface, it seems impossible to install the X11 server. Therefore, I installed the Ubuntu system on my local computer and configured the corresponding ai2thor environment, which allowed me to successfully run the code.

Hope these can help you！
