Situation

When I try to run start_http.bat, the window opens for a split second and immediately closes.

So I tried running the program through PowerShell to check the error. When running main.exe, I get this error:

FileNotFoundError: Could not find module '_internal\torch_directml\DirectML.dll'

and:

Failed to load dynlib/dll '_internal\torch_directml\DirectML.dll'

It seems that the program cannot find DirectML.dll.

What I’ve tried

• Re-downloaded the file
• Re-extracted using WinRAR
• Disabled Windows Defender
• Added folder to exclusions
• Ran as administrator

Additional Notes

The _internal\\torch_directml folder exists, but DirectML.dll is missing or not being detected.

Is this a known issue with the build, or is there something I’m missing during setup?
