Gradient Op can calculate the gradient of these inputs at the same time. But Numerical Gradient needs to calculate them one by one. So `get_numeric_gradient` is designed to calculate the gradient for one input. If you need to compute multiple inputs, you can call `get_numeric_gradient` multiple times each with a different input. ### Core Algorithm Implementation ```python - # we only compute gradient of one element a time. + # we only compute the gradient of one element a time. # we use a for loop to compute the gradient of each element. for i in xrange(tensor_size): - # get one input element by its index i. - origin = tensor_to_check.get_float_element(i) + # get one input element using the index i. + original = tensor_to_check.get_float_element(i) - # add delta to it, run op and then get the new value of the result tensor. - x_pos = origin + delta + # add delta to it, run the forward op and then + # get the new value of the result tensor. + x_pos = original + delta tensor_to_check.set_float_element(i, x_pos) y_pos = get_output() - # plus delta to this element, run op and get the new value of the result tensor. - x_neg = origin - delta + # Subtract delta from this element, run the op again + # and get the new value of the result tensor. + x_neg = original - delta tensor_to_check.set_float_element(i, x_neg) y_neg = get_output() # restore old value - tensor_to_check.set_float_element(i, origin) + tensor_to_check.set_float_element(i, original) - # compute the gradient of this element and store it into a numpy array. + # compute the gradient of this element and store + # it into a numpy array. gradient_flat[i] = (y_pos - y_neg) / delta / 2 # reshape the gradient result to the shape of the source tensor. return gradient_flat.reshape(tensor_to_check.get_dims()) ``` -## Auto Graident Checker Framework +## Auto Gradient Check Framework Each Operator Kernel has three kinds of Gradient: 1.
