I'm pretty sure i copied the correct files and renamed them before pasting them

Important notice, the first time i run the bat file (even before copying the files from Zluda) it opens the web user interface but obviously doesnt run.

After i copy and pasted the files i get this error.

Hey, which HIP SDK Version did you installed? 6.1.2 or 6.2.4 ?
And which ZLUDA Version did you download?
Also make sure your Python 3.10.11 64bit is listed in the Environment Path. If you have Python installed trough the Microsoft Store then uninstall that first and reboot, then delete the venv folder and relaunch.
Also check if its below and not above the normal Python in Path like here:

Also please screenshot how you added the C:\ZLUDA Folder and the %HIP_PATH%bin to the Environment Path.

Ok so i checked my downloads and I downloaded 6.1.2 version of HIP SDK, but i remember at the time i didn't see anything about pro driver at any point in the install.

the zluda version was also rocm6.

As for the environment variables i simply searched environment variables on windows clicked environment variable on the system properties window that pops up and then added them to the Path variable

[CS1o]

The variables need to be in the system environment not in the User environment.
See the example here: #7 (comment)

Change that and reboot the PC. Then delete the venv folder of comfyui and run the comfyui-bat again.
Then replace the DLL files again and relaunch.

[diogocorreiaf]

Ok so i did as you said and changed the variables to be in the system instead of user.

Deleted the venv and ran the bat file again, it actually opens comfyUI.

then it shut if off to put the renamed dlls and now were back to the original error

[CS1o]

Okay, damn. The caffe2 error is the hardest to fix as its cause is not known to 100%.
Its a Path or DLL issue.
Meaning rocm path or python path is not correct.

What you can try is:
Delete the venv of comfyui.
Then open up a cmd and run
Pip cache purge
Then reinstall python 3.10.11 64bit and check its correctly added in the system environment path.
Make sure your on the latest AMD Driver 24.12.1.
Reboot the PC and after that relaunch the ComfyUI bat.
After that replace the DLL files and relaunch it again.

Let me know if that worked.

[diogocorreiaf]

Well nope that didnt work, guess i will stick with Automatic1111 for now and just roll with it
Thanks for the help.

[CS1o]

No problem. If you want to use Flux you can do that in Forge with Zluda too.
Also if you want to try to get it working again with my help on Discord let me know.
