issued that starts with Layer "layer-name" is casting an input tensor
        from dtype float64 to the layer's dtype of float32. To fix, either set
        the default dtype to float64 with
        `tf.keras.backend.set_floatx('float64')`, or pass `dtype='float64'` to
        each of the Layer constructors. See `tf.keras.layers.Layer` for more
        information.
    *   Some `tf.assert_*` methods now raise assertions at operation creation
