[Issue]: IPEX Error loading c10_xpu.dll

[CraterCrater]

Issue Description

I recently installed SD.NEXT and have not been able to get it to run successfully. Every time I run it I get an error around the loading of C10_xpu.dll.

Install OneAPI and run these in CMD, then start the webui within that CMD window.

"C:\Program Files (x86)\Intel\oneAPI\pytorch-gpu-dev-0.5\oneapi-vars.bat"
"C:\Program Files (x86)\Intel\oneAPI\ocloc\2024.2\env\vars.bat" 

Then;

.\webui.bat --use-ipex

[CraterCrater]

That did the trick, awesome! Thanks!

[AndrewRainfall]

@Disty0 I don't have "pytorch-gpu-dev-0.5\oneapi-vars.bat" and "ocloc\2024.2\env\vars.bat" files.

Installed OneApi from here:
https://www.intel.com/content/www/us/en/developer/tools/oneapi/base-toolkit-download.html

---

Upd: I guess I can use those instead

"C:\Program Files (x86)\Intel\oneAPI\2025.0\oneapi-vars.bat"
"C:\Program Files (x86)\Intel\oneAPI\ocloc\2025.0\env\vars.bat"

But the second command does nothing for some reason & the C10_xpu.dll problem still there.

---

Upd 2:
So I found the solution - OneApi for some reason didn't see my VS2022.

I went Settings - System - About - Advanced System Settings - Environment Variables - System Variables - New if doesn't exist or Edit if it is wrong to "VS2022INSTALLDIR=C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools" enter your path in "" - ok - ok - ok

After that I CMD
D:\Intel\oneAPI\2024.2\oneapi-vars.bat
D:\Intel\oneAPI\ocloc\2024.2\env\vars.bat
.\webui.bat --use-ipex --upgrade --debug --autolaunch

and it finally works

Are where any way to automate this to one shortcut like it was before?
Also it feels like "D:\Intel\oneAPI\ocloc\2024.2\env\vars.bat" does nothing as SD launches without it too.

[Disty0]

D:\Intel\oneAPI\2024.2\oneapi-vars.bat is equivalent to the commands i sent and will activate the rest by itself.

You can create a new bat file to add it to the bat file.
This will be an extra step until Intel finally decides to not make it an unnecessary extra step.
