ToonCrafter Not Working with Pytorch 2.4

[davidledo]

Hello,

I had no problems working with ToonCrafter in the past, but somehow today I'm not able to run it. After about an hour of digging, I think it comes down to the version of Pytorch from one of the latest Comfy updates.

Is there a way to solve this? I tried downgrading Pytorch, but that breaks comfy.

Thanks!

Here's the error report details:

Yeah, I ran into the same issue this last week. I'm working on trying to figure it out and will let you know if I do.
