How to clip the positive gradients when using visualization_cam?

[jrmyyy]

Hello,

With the function visualization_cam, it is possible to clip the negative gradients when the parameter "grad_modifier" is set to "relu".
Is there a way to do the reverse in order to clip the positive gradients?

"Grad_modifier" can be set to "negate" but the positive gradients are unfortunately not clipped.

Thank you.
