How to set padding to "same" on nn.Conv2d?

I’m a bit of a newbie on Pytorch with some TF background. What’s the equivalent of TF’s (or conceptually speaking) padding=“same” on Pytorch? I don’t really understand the explanation of padding in the docs.

Since the input shapes are not statically defined, you would have to set the padding size manually to get the same output size.
You can find some convenience methods to calculate the padding for a specific input shapes here in the forum.
