qt.qpa.plugin error after installation (no root privileges)

[batuhanerkat]

Describe the issue:

I always used suite2p on a local computer. Recently I am trying to switch to a HPC. I installed suite2p regularly, by cloning from the git repository, on a HPC cluster through a virtual machine (noVNC). When I try to run suite2p I receive the qt error:

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, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.

I tried reinstalling and trying different suite2p versions by git checkout, still received the same error. Right now, I have the same anaconda and suite2p versions, and pip package versions as in our local computer (numpy version has an incompatibility at the latest version). As I am on a HPC, I do not have root privileges to follow the solution you suggested in this link on the installation page: https://askubuntu.com/questions/1406379/qt5-install-problem-ubuntustudio-22-04/1406503#1406503

I added these packages to conda environment trying to overcome this issue but it did not resolve:
conda install conda-forge::pyqt5.sip
conda install conda-forge::libxcb

Would it be possible to overcome this problem by using a container such as Docker or Singularity? Do you have any suggestions that I can try without using containers?
