can we use a gpu for increased speed and use of a bigger better llama2 model

[stevedipaola]

is there instructs for that - most of us AI folk have good gpus - seems silly not to use them.

two changes needed :
def build_llm(): # Local CTransformers model llm = CTransformers(model=cfg.MODEL_BIN_PATH, model_type=cfg.MODEL_TYPE, config={'max_new_tokens': cfg.MAX_NEW_TOKENS, 'temperature': cfg.TEMPERATURE, 'gpu_layers': 24} ) return llm

uninstall ctrasnformers and re-install with
CT_CUBLAS=1 pip install ctransformers --no-binary ctransformers

Thanks @alior101, it worked!
How would it integrate with poetry and pyproject.toml?

Hello,
I made the changes of llm.py

llm = CTransformers(model=cfg.MODEL_BIN_PATH,
model_type=cfg.MODEL_TYPE,
config={'max_new_tokens': cfg.MAX_NEW_TOKENS,
'temperature': cfg.TEMPERATURE,
'gpu_layers':24}

and reinstall ctransformers (0.2.27)

but seems still running very slow seems never use GPU
I already tested GPU is ready
python -c "import torch; print(torch.cuda.is_available())"
it said "True"

then I tried "python main.py "hello"" it takes 300+s to answer
please advise

Hi @alexng88 ,

I am also facing the same issues, did you get any solutions?
