I tried to install PyTorch today on a new machine. Got errors on install.

When I tried to go to download-r2.pytorch.org , im getting “SSL:SSLV3_ALERT_HANDSHAKE_FAILURE”. Even tried to bypass the error in Firefox, but wont even permit bypassing.

I see the same failure.

What’s the plain pip install command you are trying to use? I just tried to install the latest nightly and it worked fine for me.

Should be fixed now: https://download-r2.pytorch.org/ down · Issue #189056 · pytorch/pytorch · GitHub

I am installing from a requirements.txt uv pip compiled from pyproject.toml

[project]
dependencies = [
    # "vllm==0.24.0" # <== This is built for CUDA 13
    "vllm @ https://github.com/vllm-project/vllm/releases/download/v0.24.0/vllm-0.24.0+cu129-cp38-abi3-manylinux_2_28_x86_64.whl"

]
requires-python = "~= 3.13.0"

[tool.uv.pip]
torch-backend = "cu129"

So the interesting deps are:

torch==2.11.0+cu129
torchaudio==2.11.0+cu129
torchvision==0.26.0+cu129

Thanks for the update on a fix

I had the same error earlier today in my daily CI run that installs pytorch nightly (only the nightly version was affected), and on my side the bug seems now fixed!
