Is it possible to see gradient function?

[Samuel Bachorík]

Hi, when I use autograd, it is possible to see its gradient function? Or in other words, it is possible to see derivative of that function? Or is it possible to see computational graph?

For example, I want to see grad_tanh function

import autograd.numpy as np  # Thinly-wrapped numpy
from autograd import grad    # The only autograd function you may ever need

def tanh(x):                 # Define a function
       y = np.exp(-2.0 * x)
       return (1.0 - y) / (1.0 + y)

grad_tanh = grad(tanh)       # Obtain its gradient function

Thank you

Have you got the answer? I have the same problem. I need to get the formula of the first derivative of the function
