Clears the default graph stack and resets the global default graph.
tf.compat.v1.reset_default_graph()
Migrate to TF2
reset_default_graph does not work with either eager execution or
tf.function, and you should not invoke it directly. To migrate code that
uses Graph-related functions to TF2, rewrite the code without them. See the
migration guide for more
description about the behavior and semantic changes between Tensorflow 1 and
Tensorflow 2.
