Graph Visualizer: turning off node collapsing

[yaroslavvb]

TensorBoard collapses Relu-Relu_6 nodes together into one node which turns simple neural net graphs into a jumple

Example pbtxt here from resnet-8 from https://github.com/tensorflow/models

Current TensorBoard

Here's after I hack it to stop collapsing Relu nodes. Note that softmax layer is now at the top as expected, instead of middle of the graph as before

Hmm, one quick thing you can do is to select the series node and then click "Ungroup this series of nodes":

Another example pbtxt, it's resnet 14 cifar, you have to spend a few minutes uncollapsing nodes before it becomes visualizable cifar_14.txt

@davidsoergel is there a master issue for graph management?
