Hi @wallaceturner ,

Thank you for this.

Looks like it was an error with the original saved model and an older version of TensorFlow.

Have fixed this in an update and the above code should work now:

# Download pretrained model from Google Storage
!wget https://storage.googleapis.com/ztm_tf_course/skimlit/skimlit_tribrid_model.zip
!mkdir skimlit_gs_model
!unzip skimlit_tribrid_model.zip -d skimlit_gs_model

See a couple of API updates to the notebook too: https://github.com/mrdbourke/tensorflow-deep-learning/discussions/557
