GPT4All doesn't support GPU acceleration. Will add support for models like Llama which can do this
from embedai.
I was able to get GPU working with this Llama model: ggml-vic13b-q5_1.bin
using a manual workaround.
# Download the ggml-vic13b-q5_1.bin model and place in privateGPT/server/models/
# Edit privateGPT.py and comment out GPT4 model and add LLama model
# Change n_gpu_layers=40 layers based on what Nvidia GPU (max is 40). Uses about 9GB VRAM.
def load_model():
filename = 'ggml-vic13b-q5_1.bin' # Specify the name for the downloaded file
models_folder = 'models' # Specify the name of the folder inside the Flask app root
file_path = f'{models_folder}/{filename}'
if os.path.exists(file_path):
global llm
callbacks = [StreamingStdOutCallbackHandler()]
#llm = GPT4All(model=model_path, n_ctx=model_n_ctx, backend='gptj', callbacks=callbacks, verbose=False)
llm = LlamaCpp(model_path=model_path, n_ctx=model_n_ctx, n_gpu_layers=40, callbacks=callbacks, verbose=False)
# Edit privateGPT/server/.env
# Update .env as follows
PERSIST_DIRECTORY=db
MODEL_TYPE=LlamaCpp
MODEL_PATH=models/ggml-vic13b-q5_1.bin
EMBEDDINGS_MODEL_NAME=all-MiniLM-L6-v2
MODEL_N_CTX=1000
# If using conda enviroment
conda install -c "nvidia/label/cuda-12.1.1" cuda-toolkit
# Remove and reinstall llama-cpp-python with ENV variables set
# Linux uses "export" not "set" like Windows for setting environment variables
pip uninstall llama-cpp-python
export CMAKE_ARGS="-DLLAMA_CUBLAS=on"
export FORCE_CMAKE=1
pip install llama-cpp-python --no-cache-dir
Run python privateGPT
from privateGPT/server/ directory
You should see the following lines in output as the model loads
llama_model_load_internal: [cublas] offloading 40 layers to GPU
llama_model_load_internal: [cublas] total VRAM used: 9076 MB

Hi, thanks for your info.
But when I was following your step in my windows, I got this error:
Could not load Llama model from path: D:/code/privateGPT/server/models/ggml-vic13b-q5_1.bin. Received error (type=value_error)
Any idea about this? Thanks.

Hi,
I followed the instructions but looks still using cpu :

I tried this as well and it looks like it's still using CPU.. interesting. If anyone could suggest as to why it's not working with gpu, please let me know.
