This is first time to try segmentation task.
\nAt first step, I want to resize images to improve evaluation.
\nIs there anything I should care?
\n(Maybe, should I chage mask image size, too?)

Hi @whitelily,
\nYou can use Albumentation's Resize to resize your images to the desired size. Don't resize the masks, just use F.interpolate to resize your model's predictions back to 256by256 just before giving them to the loss.
\nHope this helps.
