Question

I have written a tensorflow CNN and it is already trained. I wish to restore it to run it on a few samples but unfortunately its spitting out:

Answer 1

Note that since TF 0.11 — a long time ago yet after the currently accepted answer — tf.train.Saver gained a defer_build argument in its constructor that allows you to define variables after it has been constructed. However you now need to call its build member function when all variables have been added, typically just before finilizeing your graph.

saver = tf.train.Saver(defer_build=True)
# build you graph here
saver.build()
graph.finalize()
# now entering training loop
