What is pth extension?
Just curious, thanks.

Don’t think it means anything in particular, it just seems to be a convention for files saved using torch.save(). Compare this to .pck, which is commonly used with Python’s built-in pickle.dump().

Personally I tend to use .dat data files to save and load models but as mentioned above .pth path files seem to be most prominent preference for saving models

I use .pkl for pickle.dump, fine.
.dat looks good.

Hmm, I wonder where this convention came from? Being new to pytorch, it was a bit confusing because .pth files are already used in the context of python as files in site packages that point to other directories on the system.
