Windows+Anaconda快速升级文件包（速查）

落日映苍穹つ 2024-04-18 23:00 37阅读 0赞

最近pytorch版本已经到1.20了，我还在用老版本，半年没怎么动anaconda了，决定升级新版本，  
  
但网络总是碰到问题，见怪不怪，不过每升级一次，问题都类似，所以记录一下自己的办法，也算是来个速查吧！

关于如何离线下载并安装，参考此贴的离线安装部分即可：[https://blog.csdn.net/tanmx219/article/details/82814738][https_blog.csdn.net_tanmx219_article_details_82814738]

注意我这里没有配置国内镜像，主要是以前使用镜像，貌似使用anaconda的过程中会有些其他麻烦，现在也想不起来，所以依然采取不使用镜像的办法来实现快速安装。

# #

## **要做的事很简单** ##

主要事件就是下载文件包，完成后，拷贝pytorch-1.2.0-py3.7\_cuda100\_cudnn7\_1.tar.bz2文件到D:\\Anaconda3\\pkgs，然后有两件事必须做，

其一是urls.txt要填好下载地址，我也不知道填哪个，两个都填上了，

https://anaconda.org/pytorch/pytorch/1.2.0/download/win-64/pytorch-1.2.0-py3.7\_cuda100\_cudnn7\_1.tar.bz2  
https://conda.anaconda.org/pytorch/win-64/pytorch-1.2.0-py3.7\_cuda100\_cudnn7\_1.tar.bz2

其二是解压缩（不解压缩的话，conda会默认为没有下载完成，然后删除原文件再重新下载）

## 大致做事的过程 ##

下面是我安装时的过程，

anaconda这里是下载不下来的，然后找到国内镜像

    show_channel_urls: true

我就是在这里下载的包。

关于anaconda上的下载地址，

https://anaconda.org/pytorch/pytorch/1.2.0/download/win-64/pytorch-1.2.0-py3.7\_cuda100\_cudnn7\_1.tar.bz2

conda上还有一个链接，  
https://conda.anaconda.org/pytorch/win-64/pytorch-1.2.0-py3.7\_cuda100\_cudnn7\_1.tar.bz2

下载时，最终指向的都是同一个下载地址，

[https://binstar-cio-packages-prod.s3.amazonaws.com/5a11][https_binstar-cio-packages-prod.s3.amazonaws.com_5a11]....

下载下来就可以离线安装了。
