Following the tutorial of Turning quantum nodes into Keras Layers. I changed the compile method to the following:

`model.compile(opt, loss="mae", metrics=["accuracy", tf.keras.metrics.AUC()])`

This gave the following error:

`InvalidArgumentError: cannot compute Mul as input #1(zero-based) was expected to be a double tensor but is a float tensor [Op:Mul]`

I am using `tf.keras.backend.set_floatx('float64')`

. Any help on this is appreciated.

Thank you.
