WebMay 6, 2024 · Hi!I trained the model on the ultrasonic grayscale image, since there are only two classes, I changed the code to net = UNet(n_channels=1, n_classes=1, bilinear=True), and when I trained, the loss (batch) was around 0.1, but the validation dice coeff was always low, like 7.218320015785669e-9.
