2 years ago The error is raised in your YOLO model in:
x = self.detect(x)
...
return self.act(self.bn(self.conv(x)))which gets an input activation with 128 channels while 256 are expected.
Could you check the shape of the UNet output and make sure it's compatible with your YOLO model?
I am trying to add Unet as a preprocessing layer before the YOLOv6 architecture and when I am trying to do this, I am facing the following error. And how do I combine a Unet architecture with YOLO architecture. Any help from you here will be appreciated. Looking forward to your support as soon as possible. Thank you
