Cannot Import into Custom Nodes

[yelnady]

I get the following error when trying to import cgem156-ComfyUI custom nodes using ComfyUI manager or Git Clone.

This is the error:

Thank you for the help!

Latest transformers are required. Or if you don't need dart, deleting this line may solve the problem. https://github.com/laksjdjf/cgem156-ComfyUI/blob/af194b2725b3d0abf82ea2864e0cc287c858f0e6/__init__.py#L11

Thanks updating transformers fixed it!
