The Gaussian process regression example (Gaussian Process Regression in TensorFlow Probability) is giving following error

`ValueError: No gradients provided for any variable: ['amplitude:0', 'length_scale:0', 'observation_noise_variance_var:0'].`

This error goes away when I comment out the `tf.function`

decorator.

I am using tensorflow 2.5.0.

What is the cause of the error?

I suppose that the main problem is that this and other notebooks are not under CI testing in the TFP repo.

Apparently this is fixed.

maybe it was something with libraries versioning
