build_gradient_node is not supperted for Sigmoid and Tanh.

Thanks for the great work.

When I use the Sigmoid activation function. It raises and NotImplementedError: " Function bound_forward of BoundSigmoid(name="/18") is not supported yet"

I think it is because there is no build_gradient_node function for Sigmoid and Tanh.

Do you have the plan to implement bound computing for activations like Sigmoid, and Tanh?

Hi @Walleclipse , we are working on generalizing the library to other activations but perhaps it won't be finished and released shortly.

Thank you for your reply. I am looking forward to your next version.
