Web由于pytorch会自动舍弃图计算的中间结果，所以想要获取这些数值就需要使用钩子函数。 钩子函数包括Variable的钩子和nn.Module钩子，用法相似。 hook (grad) -> Variable or None hook 不应该修改它的输入，但是它可以返回一个替代当前梯度的新梯度。 这个函数返回一个 句柄 ( handle )。 它有一个方法 handle.remove () ，可以用这个方法将 hook 从 module … WebHooks for autograd saved tensors PyTorch typically computes gradients using backpropagation. However, certain operations require intermediary results to be saved in order to perform backpropagation. This tutorial walks through how these tensors are saved/retrieved and how you can define hooks to control the packing/unpacking process. techcombank banking https://mickhillmedia.com
