got 'nan' loss

[denny1108]

Hi david,

I ran the cluttered_mnist example based on your implementation of SPN. I used exactly the same data as you, and the same code. However, I got 'nan' loss somewhere during training. Do you have any idea about this.

Thanks,

Hi denny,

tensorflow/models#181 solves the issue.
tl;dr: need to replace my softmax with tf build-in softmax.

I will also merge the updated version of my STN in TensorFlow/models with this version soon.
