Webpytorch提供了 clone 、 detach 、 copy_ 和 new_tensor 等多种张量的复制操作，尤其前两者在深度学习的网络架构中经常被使用，本文旨在对比这些操作的差别。 1. clone 返回一个和源张量同 shape 、 dtype 和 device 的张量，与源张量不共享数据内存，但提供梯度的回溯。下面，通过例子来详细说明：示例：（1）定义 WebATen is fundamentally a tensor library, on top of which almost all other Python and C++ interfaces in PyTorch are built. It provides a core Tensor class, on which many hundreds of operations are defined. Most of these operations have both CPU and GPU implementations, to which the Tensor class will dynamically dispatch based on its type.
