TORCHVISION and TORCH ARM Wheels Date Mismatch

[nWEIdia]

🐛 Describe the bug

During some manual testing we noticed that the nightly today ( pulled in torch dated 20250904 first, but then while installing torchvision 20250904 ARM wheel, it requires 20250903. Because, this torchvision build job got 20250903 pytorch version https://github.com/pytorch/vision/actions/runs/17462534604/job/49590341429#step:15:54

Is this caused by the timing when the binaries would be available? // Is this expected?

2. Vision downloading pytorch

2025-09-04T11:41:31.3818162Z + conda run -p /__w/_temp/conda_environment_17462534604 pip install torch --pre --index-url https://download.pytorch.org/whl/nightly/cu130 2025-09-04T11:42:29.2372997Z WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager, possibly rendering your system unusable. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv. Use the --root-user-action option if you know what you are doing and want to suppress this warning. 2025-09-04T11:42:29.2374481Z 2025-09-04T11:42:29.2374718Z Looking in indexes: https://download.pytorch.org/whl/nightly/cu130 2025-09-04T11:42:29.2375067Z Collecting torch 2025-09-04T11:42:29.2375692Z Downloading https://download.pytorch.org/whl/nightly/cu130/torch-2.9.0.dev20250903%2Bcu130-cp310-cp310-manylinux_2_28_aarch64.whl.metadata (30 kB)

So indeed, they are misaligned by (11:42:29 -> 13:04:37) about 1.5hours.

Might be better if vision aarch64 job could be delayed by e.g. 2 hours.
