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) Examples: 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' )ÚinprcCsRt|t ¡ƒr|St|tƒr$t|ƒSt|tƒrFtd dd„|Dƒ¡ƒSt|ƒ‚dS)NÚ.css|]}t|ƒVqdSr )r)Ú.0Úitemr r r Ú Esz3TorchVersion._convert_to_version..)rr rrrÚjoinr!)r r#r r r Ú_convert_to_version9s  z TorchVersion._convert_to_version)ÚcmpÚmethodrc sfztt|ƒ|ƒ| |¡ƒWStk r`}z(t|t ¡ƒs<‚ttƒ|ƒ|ƒWY¢Sd}~XYnXdSr )rr r)Ú BaseExceptionrr!rÚsuper)r r*r+Úe©Ú __class__r r Ú _cmp_wrapperIs zTorchVersion._cmp_wrapper) rrrrrr)rÚboolr1Ú __classcell__r r r/r r"'sr")Ú__gt__Ú__lt__Ú__eq__Ú__ge__Ú__le__cCs | ||¡Sr )r1)ÚxÚyr+r r r ÚUór;N) ÚtypingrrrrZinternal_versionrr r!rr"Z cmp_methodÚsetattrr r r r Ús  -
