"Data layer prefetch queue empty" is not an error, it's a standard notification that caffe gives you when some data layer runs to the end of its source and has to rewind to the beginning.

Hi, i was working with VGG based Segnet but i never saw this message there. Any how at present i am working with deeplab and using medical images for segmentation. there are five classes in that however when i train it, it converges to one class only. Any suggestion?
