Hello, dear Stability Matrix users, please tell me, I have all the components from AMD, I can only run the Comfortable UI on the CPU, the rest (DirectML, ROCm) gives an error, what should I do about it? The screenshot shows the error.

What GPU specifically do you have? can see if i can replicate.

Edit: actually... "Pytorch is not installed"
Can you please install ComfyUI again and in the window that comes up during install disable the "Close Dialog When Finished" button that way you can copy and paste the entire install process output here, please?

what type of model, and its precision/quant. DirectML is stale and likely running into issues these days running some models. especially with comfy-kitchen being involved. From what I can see there is no official support for DirectML for C-K.

Support for your gpu is pretty limited. SM's ComfyUI-Zluda is HIP SDK 6.4 only (and may hit the same issue), SDNext may be a better shot.
If you use SDNext you'll have to extract special rocBLAS libraries into C:/Program Files/AMD/rocm/6.2 from here:
https://github.com/YellowRoseCx/koboldcpp-rocm/releases/tag/deps-v6.2.0 (pick one, not sure which one is the best to choose)
