Tensorflow Keyword Spotting v2.1.1

[Machine Learning]

Hello!! I want to make a Tensorflow Keyword Spotting model for C in TF v 2.1.1. but it is not working. I am using this colab, but it fails when I change to the version I require. When creating the model, after training (with freeze.py) it gives a strange file. Can someone hlep me please!
