        Here’s the error end of the runtime:

        RuntimeError: stack expects each tensor to be equal size, but got [4, 144, 112] at entry 0 and [4, 136, 120] at entry 1

        Then it just exits.

        Thank you in advance!

          Hi, which lora training notebook did you use? sd 1.5, sdxl, or flux?

                I just tested the notebook with the sample training images. It is working correctly. Is this something related to your training image set?

                So… I just went and resized/cropped each image to 1024×1024 (which, to be fair, it recommends in your tutorial but then goes on to say that it’s not strictly necessary…) and it seems to be working fine.

                So, either it was the cropping that made the difference or something just started working again.

                Thanks again for the help.  I’ll report back if there ends up being a problem.   It’s currently running.

                 

                Best,
