Is it possible to visualize a tensorflow graph without a training op?

Question

I know how to visualize a tensorflow graph after training with tensorboard. Now, is it possible to visualize just the forward part of the graph, i.e., with no training opera

Answer 1

Yes, you can visualize any graph. Try this simple script:

import tensorflow as tf

a = tf.add(1, 2, name="Add_these_numbers")
b = tf.multiply(a, 3)
c = tf.add(4, 5, name="And_These_ones")
d = tf.multiply(c, 6, name="Multiply_these_numbers")
e = tf.multiply(4, 5, name="B_add")
f = tf.div(c, 6, name="B_mul")
g = tf.add(b, d)
h = tf.multiply(g, f)

with tf.Session() as sess:
    writer = tf.summary.FileWriter("output", sess.graph)
    print(sess.run(h))
    writer.close()

Then run...

tensorboard --logdir=output

... and you'll see:

So you can simply create a session just to write the graph to the FileWriter and not do anything else.
