Flux Model GPU Allocation Problem in ComfyUI

### Your question

I want to use flux , but i have only 6gb vram in my RTX 4050 gpu , so i tried "flux1-dev-bnb-nf4-v2.safetensors" with "ComfyUl" but now I am getting an error saying " SamplerCustomAdvanced
All input tensors need to be on the same GPU, but found some tensors to not be on a GPU:
[(torch.Size([1, 98304]), device(type='cpu')), (torch.Size([3072]), device(type='cpu')), (torch.Size([3072, 64]), device(type='cpu'))] "
and i reffered "https://youtu.be/tOlCoJlM4os?si=qy1XB07aEsIsSBdY" this perticular vedio to setup every thing and I am using ComfyUl though "Krita AI"
