Pytorch clone 用法
Webtorch.Tensor.detach. Tensor.detach() Returns a new Tensor, detached from the current graph. The result will never require gradient. This method also affects forward mode AD gradients and the result will never have forward mode AD gradients. 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 …

WebJan 8, 2024 · The minor optimization of doing detach () first is that the clone operation won’t be tracked: if you do clone first, then the autograd info are created for the clone and after the detach, because they are inaccessible, they are deleted. So the end result is the same, but you do a bit more useless work. In any meani…. http://www.codebaoku.com/it-python/it-python-281007.html
Webmytensor = my_tensor.to(device) 这行代码的意思是将所有最开始读取数据时的tensor变量copy一份到device所指定的 GPU 上去,之后的运算都在GPU上进行。. 这句话需要写的次数等于需要保存GPU上的tensor变量的个数;一般情况下这些tensor变量都是最开始读数据时 … Webclone ( memory_format=torch.preserve_format )→ Tensor. 返回tensor的拷贝,返回的新tensor和原来的tensor具有同样的大小和数据类型。. 原tensor的requires_grad=True. …
WebApr 14, 2024 · 大家好,我是微学AI,今天给大家带来一个利用卷积神经网络(pytorch版)实现空气质量的识别与预测。我们知道雾霾天气是一种大气污染状态,PM2.5被认为是造成雾霾天气的“元凶”,PM2.5日均值越小,空气质量越好.空气质量评价的主要污染物为细颗粒物(PM2.5)、可吸入颗粒物(PM10)、二氧化硫(SO2 ... WebThis function is differentiable, so gradients will flow back from the result of this operation to input. To create a tensor without an autograd relationship to input see detach (). input ( Tensor) – the input tensor. memory_format ( torch.memory_format, optional) – the desired memory format of returned tensor. Default: torch.preserve_format.
