git clone https://github.com/JamePeng/llama-cpp-python
cd llama-cpp-python
git clone https://github.com/ggml-org/llama.cpp ./vendor/llama.cpp
$env:CMAKE_ARGS = "-DGGML_CUDA=on"
D:\ComfyUI\venv\Scripts\python -m pip install -e . --verbose

After compilation is finished, the llama-cpp-python folder must not be deleted.

There is no need to compile it manually anymore. You can use JamePeng’s precompiled WHL package, as long as the CUDA version matches exactly.
