Not a fan of manually parsing strings tbh.

I'd prefer something like

transformers/src/transformers/utils/import_utils.py

Lines 1060 to 1075 in e032d12

	@lru_cache()
	def is_torch_greater_or_equal(library_version: str, accept_dev: bool = False):
	"""
	Accepts a library version and returns True if the current version of the library is greater than or equal to the
	given version. If `accept_dev` is True, it will also accept development versions (e.g. 2.7.0.dev20250320 matches
	2.7.0).
	"""
	if not _is_package_available("torch"):
	return False
	if accept_dev:
	return version.parse(version.parse(importlib.metadata.version("torch")).base_version) >= version.parse(
	library_version
	)
	else:
	return version.parse(importlib.metadata.version("torch")) >= version.parse(library_version)

This should catch the +cuXXX versions as well (i think). Wdyt?

@vasqu you're right, using that helper func in #37400
