So, grad_input is part of the same computation graph as grad_output and if we compute the gradient for grad_output, then the same will be done for grad_input. Since we make changes in grad_input, we clone it first. What's the purpose of 'grad_input [input < 0] = 0'? Does it mean we don't update the gradient when input less than zero? WebJul 13, 2024 · grad_input[input < 0] = 0 # for inplace version, grad_input = grad_output, as input is modified into non-negative range? return grad_input Thus, the only way for …
