There seems to be no windows builds of pytorch on conda-forge right? (This PR indicates so.) This would explain why the windows build of this feedstock fails.

While the package does import these, the metadata doesn't specify any of those nor those specific versions. Can you open an issue upstream? Also, please release the exact pins b/c that will make a nightmare to install this package in any environment.
