No matching torch==2.9.0.dev20250804+cu128 wheel for Python 3.12 – cannot install vllm==0.10.1+gptoss with official instructions
Hi team,
When following the official installation instructions for vllm==0.10.1+gptoss with Python 3.12 and CUDA 12.2, the installation fails because there is no torch==2.9.0.dev20250804+cu128 wheel published for cp312 (Python 3.12) in the referenced extra index (https://download.pytorch.org/whl/nightly/cu128/).
Steps to reproduce:
uv pip install --system --pre vllm==0.10.1+gptoss
--extra-index-url https://wheels.vllm.ai/gpt-oss/
--extra-index-url https://download.pytorch.org/whl/nightly/cu128
--index-strategy unsafe-best-match
Error:
ERROR: No matching distribution found for torch==2.9.0.dev20250804+cu128
- Python version: 3.12
- CUDA: 12.2
- OS: (e.g., Ubuntu 22.04, cloud/container)
- vllm: 0.10.1+gptoss
Expected behavior
Install should succeed following official instructions, as Python 3.12 is the officially supported version for gpt-oss.
Request
- Please publish
torch==2.9.0.dev20250804+cu128wheels for Python 3.12 in the nightly or gpt-oss index, or clarify which torch version should be used for Python 3.12. - If not supported, please update README/installation instructions or provide the expected timeline for Python 3.12 support.
Thanks!
torch==2.9.0.dev20250804+cu128 wheels do not exist for Python 3.12 at the moment, but they do for Python 3.11. You can downgrade to Python 3.11 and retry installing torch in venv.
