Error while using the placeholder function from utils_tf

[Krishuthapa]

Issue:
I am using the graph_nets library with tf2. I am trying to use utils_tf.placeholders_from_networkxs() this function to create the placeholders for my graphs to implement the EncodeProcessDecode feature. However , I am getting the following message with this:

module 'tensorflow' has no attribute 'placeholder'

Aren't the functions in the utils file compatible with the tensorflow v2?

Thanks for your comment!

Actually the concept of tf.placeholder was associated with tf.Session, and both were removed in TensorFlow 2. I would recommend looking at the TensorFlow 2 demos for some examples of how to use the library without tf.Session.
