@abetlen Can
LLAMA_BUILD=OFFbe used to get installllama-cpp-pythonwithout compilation on Windows. And grabbing the .dll for there https://github.com/ggerganov/llama.cpp/releasesWould that work? I will give it a try, and report back if I get something working.
Nevermind,
llama.cppreleases don't contain the.dll@abetlen Can
LLAMA_BUILD=OFFbe used to get installllama-cpp-pythonwithout compilation on Windows. And grabbing the .dll for there https://github.com/ggerganov/llama.cpp/releasesDo you recommend using only one variable set LLAMA_BUILD=OFF? Not using these variables set FORCE_CMAKE=1 && set CMAKE_ARGS=-DLLAMA_CUBLAS=on ? Correct?
And what path should I put the DLL in my case?
The path to my virtual environment is C:\Users\igorb\anaconda3\envs\llaman\Lib\site-packages\llama_cpp_python-0.2.6.dist-info.Tried llama in this project and there is definitely CUBLAS support here. And it is work fine,
https://github.com/oobabooga/text-generation-webuiHere some folders name from their enviroment:
llama_cpp
llama_cpp_cuda
llama_cpp_python_cuda-0.1.85+cu117.dist-info
llama_cpp_python-0.1.85.dist-infoi got stuck in the same issue
Made a PR so windows builds include the
.dllin de release .zip. See ggml-org/llama.cpp#3215For now you can use the artifacts from my branch. https://github.com/IsaacDynamo/llama.cpp/actions/runs/6206987247
With the
.dllfrom the .zip I was able to run the llama-cpp server with cuBLAS, without compiling it myself.Installed llama-cpp-python as follow.
Not sure thatUpdate: Withset CMAKE_ARGS="-DLLAMA_BUILD=OFF"changed anything, because it build a llama.cpp with a CPU backend anyway.set CMAKE_ARGS=-DLLAMA_BUILD=OFF, so without"'s llama-cpp-python skips building the CPU backend.dll.set CMAKE_ARGS=-DLLAMA_BUILD=OFF pip install llama-cpp-python[server]
Used the following commands to use the prebuild
.dllwith llama_cpp server.set LLAMA_CPP_LIB=C:\llama-release-dll-b1248-11eb9fb-bin-win-cublas-cu12.2.0-x64\llama.dll set PATH=C:\llama-release-dll-b1248-11eb9fb-bin-win-cublas-cu12.2.0-x64;%PATH% python.exe -m llama_cpp.server --model llama-2-7b-chat.Q5_K_M.gguf
@ForwardForward @IsaacDynamo I think we might be found a solution in #563 by adding
install( FILES $<TARGET_RUNTIME_DLLS:llama> DESTINATION llama_cpp )To cmake to force it to copy the cublas DLLs from the build step to the install directory.
No CUDA toolset found.This error is due to Windows CMake with MSVC requiring CUDA Visual Studio integration to be installed through the CUDA installer. This doesn't necessarily install to all of the MSVC versions you have, especially if you install a newer one after installing CUDA. You can check these paths to see if they are there:
C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\MSBuild\Microsoft\VC\v1*\BuildCustomizationsCUDA 12.2.props CUDA 12.2.targets CUDA 12.2.xml Nvda.Build.CudaTasks.v12.2.dllIf they aren't there, then the easiest way to get them is to download the CUDA installer, in your case here, and then open the installer in 7zip and extract the files to all the
BuildCustomizationsfolders in that path from this path in the installer's files:\visual_studio_integration\CUDAVisualStudioIntegration\extras\visual_studio_integration\MSBuildExtensions\You can also just run the installer again and only select the Visual Studio integration, but it may not install it to the specific version of MSVC that CMake is wanting to use.
Reacted by earonesty, yiyiChen1997, Sumit and LordF95Reacted by SumitIn the past, this wasn't as much of an issue as
scikit-buildwould handle the CUDA stuff in the background and eliminate the need for the VS integrations.scikit-build-coredoes not seem to have this functionality.@jllllll do you know if instructing users to install the nvidia provided cuda pip wheels (https://docs.nvidia.com/cuda/cuda-installation-guide-microsoft-windows/index.html#pip-wheels) would help here?
Reacted by Ramiro Perez Sanz and Luis FigueroaI don't think it will make a difference as the issue is specifically due to missing the VS integrations provided by the CUDA Toolkit installer. I've tried looking for other sources of those integration files multiple times in the past and could not find anything.
This is more of an issue with how NVIDIA has decided to implement NVCC on Windows. They could have just included CMake configuration files as part of the main NVCC package for Windows, but decided instead to distribute Visual Studio integration through the main exe installer. CMake devs themselves could also implement solutions for this and not rely on those integration files similar to how
scikit-buildandPytorchdid it. Not sure why they haven't.Then again, I'm not sure how
scikit-buildandPytorchavoided that issue. It may have actually beensetuptoolsthat implemented a solution. I'll look into it and see if it is something that can be implemented in this project.@ForwardForward Does using Ninja to build avoid the
No CUDA toolset found.issue?
It seems to for me. I removed all of my VS integration files and ran the commands below successfully.python -m pip install ninja scikit-build-core[pyproject] call "C:/Program Files/Microsoft Visual Studio/2022/BuildTools/VC/Auxiliary/Build/vcvars64.bat" set FORCE_CMAKE=1 && set CMAKE_ARGS=-GNinja -DLLAMA_CUBLAS=on python -m pip install llama-cpp-python --force-reinstall --upgrade --no-cache-dir --no-build-isolation -v--no-build-isolationseems to be needed here as llama-cpp-python does not list Ninja as a build dependency.The
callcommand activates VS's build environment and is needed here due to Ninja not automatically finding MSVC.
The oldscikit-buildhad a solution for findingvcvars64.batand activating the environment automatically. Hopefullyscikit-build-coregets that ported over soon.Reacted by Mike Ribbons, Giyeong Oh and TangbohuReacted by Mike RibbonsReacted by antiven0mReacted by Mike Ribbons and Giyeong OhI follow this instruction https://github.com/KillianLucas/open-interpreter/blob/main/docs/GPU.md

could you please help me?@wdlq That error message shows that it is trying to use Visual Studio 2015.
I would be pretty surprised if a CUDA Toolkit version as new as 12.1 supported a compiler that old on Windows.
Make sure that you have Visual Studio 2022 installed and make sure that you have selected theDesktop development with C++option during installation.7 remaining items

Another potential solution that can happen more quickly could be to include cmake in the build-system requirements:[build-system] requires = [ "scikit-build-core[pyproject]>=0.5.0", "cmake>=3.21.0" ] build-backend = "scikit_build_core.build"A simple test on my system showed that this pip installed version of cmake was immediately used to build llama-cpp-python with that addition to
pyproject.toml.
This can also allow more direct control over what version of CMake is used for building and can even make installation easier by removing the need for installing CMake beforehand.@abetlen Made a PR for the issue you linked: scikit-build/scikit-build-core#508
Code is simple enough that it doesn't really need in-depth testing on a relevant CMake version as it is simply parsing strings.
Using the version string from that issue with a Python interpreter and recreating the subprocess code for retrieving and parsing the string is enough to verify that it works.In case you were wondering, this is the string output from CMake that was being parsed and causing the error:
"cmake version 3.26.4-msvc4\n\nCMake suite maintained and supported by Kitware (kitware.com/cmake).\n"@jllllll thanks for resolving that PR, I've bumped the required scikit-build-core version to 0.5.1 which includes your fix. Sould I also add the explicit cmake build dependency in the
pyproject.toml?It isn't necessary now. It might be useful in the future? Not sure. I almost exclusively use the pip distribution of cmake anyway.
this happens if you install cuda before you install visual studio.
Check this guide and let me know if it helped
#871After spending 3 hours on installation . let me tell you what mistakes i make what should you do
step :1 download visual studion 2022 install desktop development with C++
step 2: downlaod Cuda toolkit and isntall with Express installation this will overwrite your drivers and installed correctly.
Go to cmd type nvcc --version to check if cuda is installed or not .step 3: install CUDNN
Follow this process https://medium.com/analytics-vidhya/installing-cuda-and-cudnn-on-windows-d44b8e9876b5
in this blog you have to follow all the path variables guide .Step 4: What i did was open visual studio and go to extensions and then install nvidia nsight monitor extension i don;t know if it is related to Cuda or anythig but i did to complete installation of everything .
step 5: i used pip for installation so i use these commands
set "CMAKE_ARGS=-Tv143,cuda=12.3 -DLLAMA_CUBLAS=on"

I also got stuck on running the following command:
(privateGPT) D:\AI\PrivateGPT\privateGPT>$env:CMAKE_ARGS='-DLLAMA_CUBLAS=on';
The filename, directory name, or volume label syntax is incorrect.Running the following fixed the issue:
python -m pip install llama-cpp-python --force-reinstall --no-cache-dir -v
poetry run pip install --force-reinstall --no-cache-dir llama-cpp-pythonThen when starting the server the offload to GPU is set, 33/33 layers.

Hi everyone !
I have spent a lot of time trying to install llama-cpp-python with GPU support.
I need your help. I'll keep monitoring the thread and if I need to try other options and provide info post and I'll send everything quickly.
I use:
Windows 10 Home
Intel Processor
GPU NVidia RTX 3060
I installed it on my computer:

from the point:
Installing cuBLAS version for NVIDIA GPU
File:

Contains 3 dlls:
cublas64_12.dll
cublasLt64_12.dll

It is start fine with BLAS = 1 (GPU Support) and at a faster rate.
But I need use it with Python.
