Can you tell as a bit more about your program... which modules are you using? It would be extremely helpful if you posted some code and complete error messages (both in proper tags, see help here).
Problem could be a memory leak issue, since you seem to be loading a lot of data. It can happen with tkinter and maybe even matplotlib.

I would guess it is a memory leak due to many png files you are allocating. You can do a quick check by editing the code so that you include just a few images for a test, and see if that works.

Do you load and unload the module? What happens to memory consumption when you load and unload, do you see memory linearly increasing? Can you check? And also, it may be that, when you load all those images they remain in the memory because you haven't unloaded then and therefore you have no headroom for anymore images
