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

Question

I am writing the following code in Jupyter notebook.

import tensorflow as tf
g = tf.Graph()

And I encounter the following error while executing this simple code.

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

If I execute the same from the console. It works. Any idea what's happening here.

Answer 1

Make sure you haven't called any of your python files as 'tensorflow.py'

Answer 2

I resolved this issue by restarting Jupyter Notebook kernel. It's weird.
