I’m trying to run a python script in a conda environment. Im using a ubuntu(Ubuntu 20.04.6 LTS) machine through SSH. I’m running colmap on a dataset and getting the following error:

==== running: colmap feature_extractor                 --database_path data/N3V/coffee_martini/tmp/database.db                 --image_path data/N3V/coffee_martini/tmp/images

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

** and installing packages like **libxcb-xinerama0 , libxcb-cursor0 **
None of them works.
