ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all() CloseEvent Generated

This is the code which was written in 2015 and was working fine. But now it’s giving me error while loading GUI. this function open the browse folder for selecting file. But it throws rhe error.Does it looks like an numpy error ? or matplot error please help. I am not getting any help from any tutorial.

File "D:\llfg\hrs\RS Datasets Viewer\OpenImage.py", line 150, in browse
while (wi < (self.width)) and zero == 0:

I tested with version .2, .3, .4 this file is using the spectral library. shape is from there as i Think .

I am attaching the whole code.

Numpy doesn’t have a .2, .3, or .4 version at any point in remotely recent history

You should take this up on stackoverflow - there are plenty of competent numpy users there who can direct you back here if there is indeed a bug - but you’ll need to put some effort in to help show them the problem - just pasting all your code isn’t going to get many answers
