[question] Even if v1-5-pruned-emaonly-fp16.safetensors is downloaded and saved to the checkpoints directory, an error still occurs.

[liaodalin19903]

I downloaded the v1-5-pruned-emaonly-fp16.safetensors file and saved it in the directory:

/Applications/ComfyUI.app/Contents/Resources/ComfyUI/models/checkpoints/.

However, when I ran the workflow, it still reported this error.

Disable all custom nodes and try again.

[liaodalin19903]

Hi,
1、 how to disable custom nodes?

2、
I found in the left the checkpoints count is 0.

[ltdrdata]

You can disable all custom nodes via --disable-all-custom-nodes .
And you also need to first check whether the model is actually in the folder.
