Answer 1

Cray and Shaili's answer was correct! I had a range of outcomes from 1 to 6, and the line:

tf.keras.layers.Dense(6, activation = 'softmax') 

Produced that error message, saying that things were outside of the range [0,6). I had thought that it was a labels problem (were all values present in both the training and validation label sets?), and was flogging them.
