FBGEMM Release Schedule for FBGEMM_GPU 1.4.0 with PyTorch 2.9.0 Compatibility

PyTorch 2.9.0 has been available for three weeks now, yet the latest version of FBGEMM_GPU remains at 1.3.0. We are eagerly anticipating the release of FBGEMM_GPU 1.4.0 with compatibility for PyTorch 2.9.0.

Hi @tiankongdeguiji we are currently working on releasing the builds on PyPI, as it is being blocked by storage limit issues on PyPI side. However, the wheels should be available from downloads.pytorch.org:

pip install fbgemm-gpu==1.4.1 --index-url https://download.pytorch.org/whl/test/cpu/
pip install fbgemm-gpu==1.4.1 --index-url https://download.pytorch.org/whl/test/cu126/
pip install fbgemm-gpu==1.4.1 --index-url https://download.pytorch.org/whl/test/cu128/
pip install fbgemm-gpu==1.4.1 --index-url https://download.pytorch.org/whl/test/cu129/

Hi @tiankongdeguiji, there were minor fixes for torch version compatibility checks, but no major fix

Hey @q10 , thank you for your input, just want to double check it seems that the newest version is not available for cuda 13.0. https://download.pytorch.org/whl/cu130/fbgemm-gpu/. Wanted to check is there any roadmap on this?
