I seem to have encountered a bug. JoyCaption GGUF node does not use GPU. #48

Description

@tiny-andr

My comfyuin even has a 4070ti graphics card, but it seems that the node does not use GPU for calculation. Even though I have specified GPU options.
Llama-cpp-python has been installed as follows.

Option 1: Automated installation (Recommended)

python llama_cpp_install/llama_cpp_install.py

Option 2: Manual installation

pip install -r requirements_gguf.txt

After installing llama-cpp-python using https://github.com/dougeeai/llama-cpp-python-wheels, the GPU starts to work

CMAKE_ARGS="-DGGML_CUDA=on" pip install llama-cpp-python --upgrade --force-reinstall --no-cache-dir

After executing this command and restarting ComfyUI, the problem was solved.

Thank you very much, but this page does not have wheels available for Linux.
