How do I fix this?

[Madhuparna04]

Can anyone help me with this error?

[sguada]

Can you make sure that your TF version has tf.gfile.Open, tf.gfile.Exists?

[amyzhang]

I have this same issue, and my TF version has tf.gfile.Open, tf.gfile.Exists

[alexrakowski]

It is probably related to using Python3 instead of 2 (see https://stackoverflow.com/questions/27431390/typeerror-zip-object-is-not-subscriptable ).

Cast the zip object into a list like list(zip(*_FILE_READERS))[0]
