Reproduce the import failure from the micromamba and pip commands in the issue, then inspect torchvision/init.py and torchvision/_meta_registrations.py around the torch.library.register_fake("torchvision::nms") call. Compare the reported torch 2.6.0+cu124 and torchvision 0.21.0+cu126 versions and determine what compatibility or loading condition causes the missing operator. Done means importing torchvision succeeds in the reported environment.
