clip using CPU backend

Open onthemove31 opened this issue 1 month ago • 7 comments

Although I have CUDA enabled and everything installed properly, joycon runs on CPU backend. Any way to fix this? I am running this on Windows with CUDA 12.8 and RTX 3080TI

I have the same thing, cu130 5070

Update: Nightly version fixed it, maybe I was missing requirements since I last used the node

I'm also experiencing this problem. Could you please tell me what the cause is? I've confirmed that the GPU is available, but it's only using the CPU.

can you specify where you got the nightly version from?

From within the comfyui manager, looking back I did also reinstall llama-cpp-python manually which could have been the main reason. Like I said I was probably missing requirements

great, will try this out

Same problem here. Uses only CPU. Similar node from another author works perfect but doesn't have Model unload from memory.

can you share the alternate node?
