kaylimekay opened a new issue #8602: Compute Jacobian using contrib.autograd.grad()
URL: https://github.com/apache/incubator-mxnet/issues/8602
 
 
   The very nice grad() function in contrib.autograd computes the gradient of a scalar function with respect to an arbitrary number of inputs.
   
   Is there a recommended way to extend this so that it automatically computes the gradients of a vector-valued function, i.e. the Jacobian?  In other words, given a function that returns an array of size N and takes M inputs, grad() would give an NxM array, where each element of the array is the gradient of one of the outputs w.r.t one of the inputs?
