Version parsing fails on pytorch alpha

[keturn]

Pytorch may reportedly have a version string like 2.0.0a0+gitd1123c9 when compiled from source. That makes the safetensors Version parser fail with Python patch version not an integer

safetensors/bindings/python/src/lib.rs

Lines 463 to 465 in ba8de5f

	let patch = patch_str
	.parse()
	.map_err(|_| "Python patch version not an integer")?;

Fixed by hacking the file `version` in PyTorch.

Ok, thanks for the clarification !.
Need to change that error message, I couldn't even find it.

And in case the version cannot be parsed we can adopt a default behavior instead of crashing. Thanks for the tip !
