AttributeError: module 'tensorflow' has no attribute 'gfile'

This error occurs when TensorFlow version 2 or above is being used, and the code is referencing the deprecated module `gfile` from TensorFlow version 1.

To resolve this error, replace `tensorflow.gfile` with `tensorflow.io.gfile` in the code. For example, if the code has the line:

import tensorflow as tf
...
with tf.gfile.GFile(filename, 'rb') as f:
    ...

Change it to:

import tensorflow as tf
...
with tf.io.gfile.GFile(filename, 'rb') as f:
    ...

This should resolve the error and allow the code to run without issues.
