Incorrect redirect: finetuning_torchvision_models_tutorial → Object Detection tutorial

[sjp611]

Problem

The URL https://pytorch.org/tutorials/beginner/finetuning_torchvision_models_tutorial.html
now redirects to torchvision_tutorial.html (Object Detection), but these are completely different tutorials:

	Original (removed)	Redirect target
Task	Image Classification	Object Detection
Dataset	hymenoptera_data (bees/ants)	Penn-Fudan (pedestrians)
Model	ResNet, VGG, AlexNet, etc.	Mask R-CNN

Impact

This broken redirect is affecting other projects. For example:

• Ray documentation had to fix this: ray-project/ray#60036

Original tutorial content

The original tutorial still exists in mirrors:

• https://brsoff.github.io/tutorials/beginner/finetuning_torchvision_models_tutorial.html

Suggestion

Either:

1. Redirect to transfer_learning_tutorial.html instead (same dataset, same task)
2. Or restore the original tutorial
