I have the same problem.Do you solve it?

Met same problems to reproduce the code.

I got the same here

joaolcaas commented 5 years ago

4 alredy solve this problem.

Hi, I got that problem too. I solved this problem by revising code. In the file named 'save_restore.py', in 87Line, "with tf.io.gfile.GFile(os.path.join(filename, basename)) as fp:" I fixed to "with tf.io.gfile.GFile(os.path.join(filename, basename), 'rb') as fp:"

And it worked! Thank you!!
