tensorflow C 或 C++ API 中是否存在等效于 tf.gradients function 的值？

Question

I want to implement a tensorflows function tf.gradients in C or C++ API? Tensorflow C++ has the worst documentation in the world and C API aren't documented at all. Can you suggest if there is an implementation or which API parts should I use to develop this myself.

Answer 1

The C functions that the python function tf.gradients calls on can be found in the following header file:

#include "tensorflow/core/gradients/grad_ops.h"

You can use tensorflow::GradientTape to initialize a tape which the can call on the gradient function to compute the gradient of a tensor y in respect to x .
