Install any of our PyTorch binaries built with CUDA 12.8+ using the install command from our install matrix. E.g. a simple pip install torch will install torch==2.8.0+cu128 on Linux x86 systems supporting Blackwell GPUs:
EDIT: From your cross-post:
My Python version is 3.8.10 and CUDA is 12.8. Using the official pip and Nightly commands to download PyTorch 12.8 shows that this version cannot be found
This is expected as Python >= 3.9 is needed as described on the install page:
NOTE: Latest Stable PyTorch requires Python 3.9 or later. Latest Preview (Nightly) PyTorch requires Python 3.10 or later.
so update your Python version and rerun the install command. @mia2
