I am defining a sequential Keras model using tensorflow.keras

Runtime: Databricks ML 8.3

Cluster: Standard NC24 with 4 GPUs per node.

To enable XLA compilation, I set the following flag:

tf.config.optimizer.set_jit(True)

Here is the output when I try to train the model:

<command-4238178162238395> in train_distributed_tf(train_count, val_count, params)

18 metrics=['mean_absolute_error', 'mean_absolute_percentage_error'])
