-Install Via git Url https://github.com/TTPlanetPig/Comfyui_JC2 or inside the folder ./comfyui/custom_nodes run
git clone https://github.com/TTPlanetPig/Comfyui_JC2
-for python_embeded comfyui version, inside folder ./comfyui/custom_nodes/Comfyui_JC2 run
../../../python_embeded/python.exe -m pip install -r requirements.txt
I will assume you have the pytorch ready in your PC, in case you don't, install from here:
pip install torch==2.4.0 torchvision==0.19.0 torchaudio==2.4.0 --index-url https://download.pytorch.org/whl/cu121
# (NOT Recommended if you don't familar with embeded python)
Model preparation:
-clip vision: https://huggingface.co/google/siglip-so400m-patch14-384/tree/main download all files and place in ComfyUI\models\clip_vision\google--siglip-so400m-patch14-384
-LLM: https://huggingface.co/unsloth/Meta-Llama-3.1-8B-Instruct download all files and place in ComfyUI\models\LLM\unsloth--Meta-Llama-3.1-8B-Instruct
-Joy capiton lora: https://huggingface.co/spaces/fancyfeast/joy-caption-alpha-two download all files and place in ComfyUI\models\Joy_caption\cgrkzexw-599808, i will suggest you use huggingface-cli to avoid mistaken on the names.

Make sure your model is well placed as below.
Key options:
-
For 3090/4090 use bf16 otherwise nf4. please notice nf4 accuracy is lower than bf16, you can directly figure out.
-
For differnt purpose on the prompts
-
not always longer is better:
-
if enabled, the loaded clip,llm,lora model will not offload
-
if enabled, all the extra option will be effective. if disabled, even you enabled in detail options.
