Where can I train with TF v 2.1.1

[mlprojectsam]

Hello sir, thank you so much for making this library. I know that updating must be diffuclt, but can you share a notebook or colab where I can train a Microspeech for Tensorflow v 2.1.1. I am currentrly using this colab: https://colab.research.google.com/github/tinyMLx/colabs/blob/master/4-6-8-CustomDatasetKWSModel.ipynb#scrollTo=lBj_AyCh1cC0

I make the change from TF v 2.4.1 to 2.1.1 at the beginnig. But after training the model, when I try to generate the it with freeze.py, a strange file is created.

Can you help me build a model that works with this library please or what can I do to have a keyword spotting program for ESP32?

Thank you very much, Best regards
