Help with "out of memory" message

[ClothingAI]

Hey
I usually have a good GPU,
but I recently got a problem with pytorch library in comfyui so i tried to fix it and it seemed to work fine,
but when I tried catVTON (which caused this problem with pytorch btw)
I got this error:
`!!! Exception during processing !!! Allocation on device
Traceback (most recent call last):
File "C:\Users\aaas\AI\ComfyUI_windows_portable\ComfyUI\execution.py", line 317, in execute
output_data, output_ui, has_subgraph = get_output_data(obj, input_data_all, execution_block_cb=execution_block_cb, pre_execute_cb=pre_execute_cb)

torch.OutOfMemoryError: Allocation on device

Got an OOM, unloading all loaded models.

I tried modifyin the choice of segmentation model in that particular node, but same result!
What is wrong?
Thanks

same.Strangely, I successfully ran the workflow once and then encountered this issue when I ran it again.

Yeah, I think I read inside another post a solution about changing a value on the catvon node, somethign about using fp16 or something.
