windows下完全离线安装Anaconda+Tensorflow

由于某些原因，需要在不联网的windows电脑上安装Anaconda和Tensorflow，先是进行准备工作，将各种需要的安装包下载好，再进行完全离线安装。本次安装是基于Anaconda3-2021.05-Windows-x86_64与tensorflow-2.6.0-cp38-cp38-win_amd64。文后我会放上tensorflow的离线安装需要的支撑包下载地址。Anaconda和Tensorflow的包比较大，可以自行下载，我也会放上地址。

一、准备工作

1.Anaconda的下载：https://www.anaconda.com/download/
2.Tensorflow的下载，可以去清华大学开源软件镜像站：https://mirrors.tuna.tsinghua.edu.cn/tensorflow/windows/，注意cpu版和gpu版，根据自己需要。
3.Tensorflow的支撑包，这里我列下各支撑包的名称，供参考，也可以直接下载我的支撑包合集(内含protoc、protobuf以及支撑包的支撑包)：https://download.youkuaiyun.com/download/wenye23/21710860

二、安装过程

1.安装Anaconda，这个教程太多了，也比较简单，注意加入环境变量，略过了；
2.进入Anaconda安装路径，到\Lib\site-packages目录下，创建文件夹tensorflow；
3.在创建的tensorflow文件夹中，解压上文下载的支撑包.rar，将支撑包文件夹中的所有文件都放到tensorflow文件夹中；
4.将tensorflow-2.6.0-cp38-cp38-win_amd64.whl文件放到tensorflow文件夹中；
5.解压protoc-3.17.3-win64.zip，将bin中的protoc.exe复制到C:\windows\system32中；
6.直接解压protobuf-python-3.17.3.zip，得到protobuf-3.17.3.文件夹，将第5步中的protoc.exe文件也复制到protobuf-3.17.3\src文件夹中；
7.在cmd命令中更改路径，进入到\Lib\site-packages\tensorflow\protobuf-3.17.3\python路径中，执行python setup.py install;

8.切换安装路径到\Lib\site-packages\tensorflow，接下来先安装tensorflow的各支撑包，可参考上面的支撑包列表，有些包的顺序不一定会对，按提示进行安装，根据文件的不同有两种安装方式如下：
8.1 whl文件直接就利用pip install 文件名，例：

8.2 压缩文件形式的安装，与安装protobuf一致，先解压，然后切换路径，再执行python setup.py install。下面以clang-5.0.tar.gz的安装为例：将clang-5.0.tar.gz解压至当前文件夹(tensorflow)下，在cmd中将路径切换到\Lib\site-packages\tensorflow\clang-5.0，再执行python setup.py install

9.将支撑包与tensorflow包都安装完成后，电脑就成功的装上了tensorflow。可以重新打开cmd，执行
python
import tensorflow
进行验证。
如果是gpu版本，需要安装对应版本的CUDA和cuDNN。

三、提示

因不同人员的电脑不尽相同，可能会出现需要的支撑包不同的情况，下面附上下载支撑包的网址，直接搜，下载对应版本就行。

希望有帮助，祝安装顺利。
