The installer should have include a selector for RTX 5000 series with pytorch 2.8.0 / Cuda 12.8 by now. I guess i'm going back to the manual installation way with...

The only way I could get it to work was by doing clean manual install, then pytorch 2.8.0 over and latest bitsandbytes from the GH repo. After that had to...

> Cannot install bitsandbytes i do this: pip install --force-reinstall --no-cache-dir bitsandbytes then a lot gets uninstalled, downloaded and reinstalled. But then? ERROR: pip's dependency resolver does not currently take...

@Blackjack356 I haven't checked with the latest comfy updates, but before i had to mute the Comfy function that disables the torch compile in the code. This function seems to...

Is there more information about this? Has anyone managed to fix the black output? I'm using sage with --use-sage-attention startup argument. Previously in Wan2.1 I would get a black image...

Works well now. Compiled from the stable branch stable_abi3 from @woct0rdho repo and silenced the annoying torch.compiler.disable() function. The good old torch compile functions are back, memory utilization is gold...

> Do you mind sharing a link to the branch? @StrongerXi Sure. It's this one: https://github.com/woct0rdho/SageAttention.git ( abi3_stable branch for pytorch >= 2.9 ) Also, the **torch.compiler.disable()** function seems to...
