Thank you for your hardwork. hope you can advise how to resolve this.

I am also suffering from the same error. I'd like to hear some advice.

You may want to try updating the custom node. Btw, you're using a folk of this repo.

same wrong....

If you are all using ComfyUI-AnimateDiff-Evolved, please open a new ticket here: https://github.com/Kosinkadink/ComfyUI-AnimateDiff-Evolved/issues

update custom_nodes

[gogdodog]

in the path "ComfyUI\custom_nodes\ComfyUI-AnimateDiff-Evolved\animatediff", open the file "motion_utilis.py", in the line 33 replace the lines " class CrossAttentionMM(nn.Module):
def init(self, query_dim, context_dim=None, heads=8, dim_head=64, dropout=0., dtype=None, device=None, operations=comfy.ops):
super().init()
inner_dim = dim_head * heads
context_dim = default(context_dim, query_dim)"

for

"class CrossAttentionMM(nn.Module):
def init(self, query_dim, context_dim=None, heads=8, dim_head=64, dropout=0., dtype=None, device=None,
operations=comfy.ops.disable_weight_init if hasattr(comfy.ops, "disable_weight_init") else comfy.ops):
super().init()
inner_dim = dim_head * heads
context_dim = default(context_dim, query_dim)" , save and you're done.

Anyone experiencing this issue, either your ComfyUI is badly outdated by 2+ months, and/or your ComfyUI-AnimateDiff-Evolved is badly outdated. Update whichever one is outdated to fix your issue.

If you are using collab or something of that nature, whatever you may have been trying to update ComfyUI was not working, making you not get any ComfyUI updates for the past few months. If you're in that boat, try to recreate ComfyUI from scratch or a different method to update. As for AnimateDiff-Evolved, that should update without any issues.
