Save Tensorflow graph for viewing in Tensorboard without summary operations

Question

I have a rather complicated Tensorflow graph that I\'d like to visualize for optimization purposes. Is there a function that I can call that will simply save the graph for v

Answer 1

This worked for me:

graph = tf.Graph()
with graph.as_default():
    ... build graph (without annotations) ...
writer = tf.summary.FileWriter(logdir='logdir', graph=graph)
writer.flush()

The graph is loaded automatically when launching tensorboard with "--logdir=logdir/". No "upload" button needed.
