RunTimeError : Size of Tensros must match except in dimension 1

[Jiwno]

Hi, I'm having trouble with training pix2pix model with my data.
I have a run time error that I've never seen it before when I use other datasets.
is there any solution to figure this out?

python train.py --dataroot .\datasets\soolsool_5760_2880_60_30 --name soolsool_v1 --model pix2pix --direction BtoA --load_size 1440 --crop_size 1440 --preprocess none --no_dropout --input_nc 4 --output_nc 4

error message : Sizes of tensors must match except in dimension 1. Expected size 45 but got size 44 for tensor number 1 in the list.
