ValueError: An operation has `None` for gradient. Please make sure that all of your ops have a gradient defined (i.e. are differentiable). Common ops without gradient: K.argmax, K.round, K.eval.

as I replaced "model.compile(loss=loss, optimizer='adam')" in my code as "model.compile(RAdam(), loss='mse')", I got "ValueError: An operation has None for gradient." error, how to solve this ?

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?
