The neural synth notebook is written using Tensorflow 1.15. I'd like to rewrite the notebook to work on tensorflow 2.x before upgrading.

I ran neural synth notebook with tensorflow 2.6.0 with no problem. The most problem is with scipy where many methods are no longer available. But I was able to change them.

The code I used for make tensorflow 1.x compatible is:
import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()

Thank you for the PR. thanks for correcting the code mistakes. unfortunately though this commit includes the entire (54+ MB) inception model in it, which can't go into the repo due to space constraints. Otherwise I'd merge this in. if you can remake the PR without including large binaries, please do. thanks!
