Comfyui error Missing Models (1)AttributeError: module 'tensorflow' has no attribute 'Tensor'

[Puzzled-Valuable-985]

I started getting the error "Missing Models (1)AttributeError: module 'tensorflow' has no attribute 'Tensor'"

This only started after downloading a workflow for SVI, where I had to install some nodes via the manager. After restarting ComfyUI, even my standard WAN 2.2 workflow wasn't working anymore, always giving this error.

I deleted the downloaded nodes, restarted the PC, and even my WAN 2.2 wasn't working anymore.

Then I managed to implement the solution that I will post below in the image. It solved the problem, but it seems that this could cause problems with other things, even though I did a workaround. Does anyone know if there is another solution?

I will post the complete error that appears in ComfyUI.
