About training in deep network.

[wangq95]

Hi, @MarvinTeichmann
Thanks for your work, I have two questions about the ConvCRF.

1. I run demo.py and got a perfect result, but how the weights of Gaussian Kernels been updated?
2. I put the ConvCRF as a module into a deep network, and train the whole network by BP for semantic segmentation, No error but the loss is so unstable and the mIoU is too low. How should I choose the training protocol？

Thanks a lot.
