Errors during model loading

[doogyhatts]

Looks like I ran into the same set of errors that occur when using the other fork as well. Interestingly, in this case, I had to queue prompt before the error started appearing, while for the other fork it simply appeared during ComfyUI loading.

I did do the requirements.txt installation as well.

Error occurred when executing DynamiCrafterModelLoader: cannot import name '_TORCH_GREATER_EQUAL_1_13' from 'lightning_fabric.utilities.imports' (C:\tools\StabilityMatrix\Packages\ComfyUI\venv\lib\site-packages\lightning_fabric\utilities\imports.py)

As you are using StabilityMatrix, how exactly did you install the requirements.txt?

[doogyhatts]

Ok I figured out the solution. install pytorch_lightning separately using the ComfyUI-manager.
