SwinUNETR input image_size problem.

[justinzhang528]

Dear MONAI Community,

I used image_size 128x128x48 to train SwinUNETR model but the error showed "input image size (128x128x48) should be divisible by stage-wise image resolution". I was confused about why my image_size didn't work?

Thanks in advanced!

Hi Justin, thanks for the question, the swin transformer for 3D requires a downsample/upsample factors of 16, can you try 64 in the third dimension?

It works for me to set 64 in the 3rd dimension, thanks. So the resolution should be divisible by 32 ?

It might be at least 64. Then 96, 128 also work.

got it, thanks.
