The RGB of predict result is always (255, 255, 255)

Hi k3nt0w,
I use your FCN to do semantic image segmentation.
After I train FCN and run predict.py (visualize(predict("2011_003151", "FCN"), "2011_003151")), the result image is always blank.
I have no idea about this result.
Could you have any suggestion?

There is my training result:
python train.py
Using Theano backend.
