What is difference between .pt, .pth and .pwf extentions in PyTorch?

[Davis777]

I have seen in some code examples, that people use .pwf as model file saving format. But in PyTorch documentation .pt and .pth are recommended.

I used .pwf and worked fine for a small 1->16->16 convolutional network.

My question is what is the difference between these formats?

Why is .pwf extension not even recommended in PyTorch documentation and why do people still use it?

I think you're in the wrong forum.
