Hello.
Now I’m trying to create channels-first semantic segmentation model of 2D U-Net with tensorflow v2.5.
Learning phase can run, but the accuracy remains very low (it’s about 0.001-).
I could get high accuracy by channels-last (about 0.9-).
What should I have to confirm ?

Input shape: (None, 1, 256, 256)
Output shape: (None, 5, 256, 256)
class num: 5
loss : mse
optimizer: adam
Thank you.
