Desperate Plea for assistance: I got it working, but then tested H2OGPT. Bad idea! When back to PrivateGPT and can no longer build due to llama-cpp-python wheels

[csocha]

Hi,
This is a hail mary after spending countless hours on this. At this point, I'm desperate and sad because I can't get back to it working again.

Back story: After much effort, I finally got PrivateGPT working on my Windows 10 box. After enjoying it for a few days, I wanted to see how H2oGPT worked so I used their window installer. BIG MISTAKE. Not only could I not get H2OGPT to work on my local machine, I now cannot get PrivateGPT to run anymore, or install, or anything due to the llama-cpp-python wheels error.

I get the error as shown below. The steps I've taken to try to resolve it are as follows:

• Uninstalled VS.NET 2022 Community
• Uninstalled MinGW GCC
• Updated PIP (already had the latest version)
• Rebooted
• Reinstalled VS.NET 2022 Community
  • Installed C++ CMake tools for Windows
  • Installed MS Build Tools 2022
  • There is nothing call Universal Windows Platform Development in Windows Installer. Assuming it comes built into Visual Studio.net 2022
• Reinstalled MinGW and selected:
  • ming32-gcc-g++ (The GNU C++ Compiler) version 6.3.0-1
  • Also tried with mingw32-base
• Made sure c:\minGW\bin is in the system environment variable
• I can type gcc from the terminal in VS.Code. It can find it.
• I even tried to force it using, but same error: pip install llama-cpp-python --force-reinstall --upgrade --no-cache-dir
• pip version is v3.10 and is up to date.
• I'm on an Intel
• I have read tons of threads here and on google for this error no avail. It was working but now it's dead Jim.

### The error I am getting is shown below:

ERROR: Failed building wheel for llama-cpp-python
Failed to build llama-cpp-python

Update:
I found a thread about popping up Visual Studio Installer and launching the Visual Studio Build Tools 2022. I then navigated to the folder I had PrivateGPT in and it successfully built the llama.cpp.python file.

I noticed that when I do a c:\PATH using the Select Developer Command Prompt for VS 2022 , I get a totally different set of paths than if I do it in VS.CODE terminal, so clearly something is up with the path discrepancy all things being equal. Not specifically what yet.

Can verify: This fixed it.

Wait, can you detail more on this?
