".pth" is not recommended

[marsianjohncarter]

While going through the course, I wanted to figure out why we use .pt or .pth for model extensions. The first site that popped up:

https://stackoverflow.com/questions/59095824/what-is-the-difference-between-pt-pth-and-pwf-extentions-in-pytorch

The answer there states:

...it is however not recommended to use .pth extension
when checkpointing models because it collides with Python path (.pth) configuration >files. Because of this, I myself use .pth.tar >or .pt but not .pth, or any other extensions.

There is an issue open for this:
