KeyError: "correlation"

[David3310273]

Hello, I want to get the output flow images from your CSS_ft model, the code I wrote is showing below:

import tensorflow as tf
import os

ckpt_path = "~/UnFlow/logs/CSS_ft"

with tf.Session() as sess:
    saver = tf.train.import_meta_graph(os.path.join(ckpt_path, "model.ckpt.meta"))
    saver.restore(sess, tf.train.latest_checkpoint(ckpt_path))
    print("finished!")

when I execute the code, it shows the error like this:

Traceback (most recent call last):
  File "export_endovis.py", line 8, in <module>
    saver = tf.train.import_meta_graph(os.path.join(ckpt_path, "model.ckpt.meta"))

    op_def = op_dict[node.op]
KeyError: 'Correlation'

please help me out, thanks!

It looks like the Correlation op was not compiled. Did you run the run.py script? This is needed for some initialization, including op compilation. Note that you may need to use an old version of tensorflow for compilation to work.
