Wheel build showing error of cmake suddenly - building version 0.2.76 on windows

[himanshu034]

I was using 0.2.76 version of llama-cpp-python previously and it was working fine on my windows machine. Now suddenly started getting error as below:
Command to install:
pip install --trusted-host abetlen.github.io --extra-index-url https://abetlen.github.io/llama-cpp-python/whl/cpu llama-cpp-python==0.2.76 --verbose

note: This error originates from a subprocess, and is likely not a problem with pip.

Please let me know if I am missing anything and it will be great to get solution for this issue.

I have the same issue with you.

Mine is as attached. And my version v2.90 rather than 2.76

What I have done to date

• I have upgraded my pip to the latest version
• Tried installing VS code C++ build compiler to the latest version, I have Visual Studio Build Tools 2002 v17.11.2 installed
• Also downloaded CMake v3.30 from cmake.org/ via binary distribution as it was complaining about missing Cmake however it is not solving the issue and giving me that error message attached

Any suggestion for us software experts?

Hi @himanshu034,

Try this, here are my troubleshooting steps

1. Ensure that Python is properly installed, write this on your Windows command prompt
   python --version
   Expected: Python 3.12.4 or something similar
2. Ensure that pip is installed properly
   pip --version
   Expected: pip 24.2
3. Ensure the latest version of Python build dependencies are installed in your machine:
   pip install --upgrade pip setuptools wheel scikit-build-core
   Expected: Successfully installed ....."scikit-build-core-0.10.6, setuptools-75.0.0, wheel-0.44.0"
4. Check for architecture issues
   python -c "import struct; print(struct.calcsize('P')*8)"
   Expected: if your machine is 64-bit, the expected output should also be 64-bit
5. Create a Virtual environment in your machine so it doesnt get tangled with your main machine
   DM if you need help with this step
6. Check CMake installation is correct
   To check, type this in your Windows command prompt
   cmake --version
   Expected: cmake version 3.29.8

After getting the basics downpacked, if still facing issues with CMake Errors like I gotten them as well

Try the following advanced troubleshooting steps

1. Ensure the required build tools are installed properly
   Download Microsoft Visual Studio Community 2022 (FREE VERSION) i.e. 17.11.3
   Select the right components because the problems we are facing is that
   - missing C and C++ compilers
   - cannot locate NMake
2. To solve these issues:
   - Run the installer .exe and in the Visual Studio Installer select Desktop development with C++
   - Make sure the following components are checked:
   - [1] MSVC v143 - VS 2022 C++ x64/x86 build tools
   - Windows 11 SDK (should automatically selected)
   - C++ CMake tools for Windows
   - C++ build tools core features (should automatically selected)
   - NMake is automatically selected as long as Desktop development with C++ workload is selected

To verify that NMake is installed with your installation

1. Open Developer Command Prompt in your Windows START menu

2. Run the following command:
   nmake /?
   Expected: Microsoft (R) Program Maintenance Utility Version 14.41.34120.0
   Copyright (C) Microsoft Corporation. All rights reserved.

   Usage: NMAKE @commandfile
   NMAKE [options] [/f makefile] [/x stderrfile] [macrodefs] [targets]

   Options:
   .....

SUCCESS!!! You should see that the above checker, suggest that NMake is properly installed in your machine

You can continue and that should solve your issue

Let me know how you get on
