COLMAP running error in remote server while running Non-Rigid NeRF - deep-learning

Question

I was checking the github code of LLFF : https://github.com/Fyusion/LLFF, Non-Rigid NeRF : https://github.com/facebookresearch/nonrigid_nerf and followed the suggested steps to install requirements. While running a preprocess file which return poses from images by SfM using COLMAP. I was getting the following error while executing the preprocessing in a remote server. Can anyone please help me with solving this?
python preprocess.py --input data/example_sequence1/
Need to run COLMAP
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc, webgl, xcb.
