"**Warning**: there's currently a bug in TensorFlow 2.8.0 ([issue #54459](https://github.com/tensorflow/tensorflow/issues/54459)) which prevents using a `StringLookup` layer inside a model, so the next 4 cells will fail. If you run into this issue, you must either skip these cells, or downgrade to TensorFlow 2.7.1 (e.g., using `%pip install tensorflow~=2.7.1`) and run the notebook again. I'll update this notebook as soon as the bug is fixed, or when a better workaround exists."
