Nvidia Blackwell 50XX GPU instructions (Windows)

[w-e-w]

As PyTorch have not yet released a compatible builds for Blackwell GPUs
we have been allowed to publish Early Access PyTorch wheels by Nvidia

---

There are several methods to run on Blackwell 50XX GPUs

Method 1: use the a new standalone release

Recommended for new install or for those not familiar with terminals / commands)

we have prepared a standalone release for Windows which can be downloaded here sd.webui-1.10.1-blackwell.7z (1.8GB)

1. Download sd.webui-1.10.1-blackwell.7z
2. Extract using 7z

Windows 11 seems to have it added native 7z support

3. Click run.bat to launch webui

note: do not enable --xformers, currently it is not compatible

Method 2: use the latest dev branch

Recommended for those who are migrating from existing installation and for those who are familiar with commands and terminals

• As of Blackwell compatibility (Windows only) #16817 the dev branch have been update with auto detection of blackwell GPUs, when detected it will automatically install the appropriate PyTorch which version

1. Follow the guide on how to switch branches see wiki How to switch to different versions of WebUI

instead of the release_candidate in the example substituted with dev to switch to dev branch

2. Add --reinstall-torch to COMMANDLINE_ARGS to tell webui to reinstall PyTorch
3. Launch webui

remember to remove--reinstall-torch from COMMANDLINE_ARGS after it's done reinstalling PyTorch

Method 3: manual upgrade

Meant for developers
