Place the model in the models
folder, making sure that its name contains ggml
somewhere and ends in .bin
.
Follow the instructions in the llama.cpp README to generate the ggml-model.bin
file: https://github.com/ggerganov/llama.cpp#usage
Enabled with the --n-gpu-layers
parameter. If you have enough VRAM, use a high number like --n-gpu-layers 200000
to offload all layers to the GPU.
Note that you need to manually install llama-cpp-python
with GPU support. To do that:
pip uninstall -y llama-cpp-python
CMAKE_ARGS="-DLLAMA_CUBLAS=on" FORCE_CMAKE=1 pip install llama-cpp-python --no-cache-dir
pip uninstall -y llama-cpp-python
set CMAKE_ARGS="-DLLAMA_CUBLAS=on"
set FORCE_CMAKE=1
pip install llama-cpp-python --no-cache-dir
Here you can find the different compilation options for OpenBLAS / cuBLAS / CLBlast: https://pypi.org/project/llama-cpp-python/
This was the performance of llama-7b int4 on my i5-12400F (cpu only):
Output generated in 33.07 seconds (6.05 tokens/s, 200 tokens, context 17)
You can change the number of threads with --threads N
.
