Thanks to your efforts and contribution, on NPYViewer ,great tools.
But, on latest OS environment, there's some pip install packages errors.
So, I found , it cause by PyQT5==[oldversion] static version fix.
Finally I removed fixed version, It works well on python3.13
please update PyQT5 , in requirement.txt prevent NPYViewer to run on latest windows.
PyQt5
numpy
pandas
matplotlib
scipy
networkx
