WARNING:tensorflow:Keras is training/fitting/evaluating on array-like data. Keras may not be optimized for this format, so if your input data format is supported by TensorFlow I/O ([GitHub - tensorflow/io: Dataset, streaming, and file system extensions maintained by TensorFlow SIG-IO](https://github.com/tensorflow/io)) we recommend using that to load a Dataset instead.  
Epoch 1/10  
WARNING:tensorflow:AutoGraph could not transform \<function Model.make\_train\_function..train\_function at 0x000001BF037591F8\> and will run it as-is.  
Cause: closure mismatch, requested (‘self’, ‘step\_function’), but source function had ()  
To silence this warning, decorate the function with @tf.autograph.experimental.do\_not\_convert
