mmengine.utils.dl_utils.TORCH_VERSION

mmengine.utils.dl_utils.TORCH_VERSION = '2.2.2+cu121'

A string with magic powers to compare to both Version and iterables! Prior to 1.10.0 torch.__version__ was stored as a str and so many did comparisons against torch.__version__ as if it were a str. In order to not break them we have TorchVersion which masquerades as a str while also having the ability to compare against both packaging.version.Version as well as tuples of values, eg. (1, 2, 1) .. rubric:: 示例

Comparing a TorchVersion object to a Version object

TorchVersion(‘1.10.0a’) > Version(‘1.10.0a’)

Comparing a TorchVersion object to a Tuple object

TorchVersion(‘1.10.0a’) > (1, 2) # 1.2 TorchVersion(‘1.10.0a’) > (1, 2, 1) # 1.2.1

Comparing a TorchVersion object against a string

TorchVersion(‘1.10.0a’) > ‘1.2’ TorchVersion(‘1.10.0a’) > ‘1.2.1’
