Windows环境下使用tensorflow opencv的小事儿

安装

一、anaconda+tensorflow+opencv+spyder

二、python+tensorflow+opencv+pycharm

三、python3.5+tensorflow-gpu1.3+cuda8.0+cudnn6.0

这两种方式我都尝试过了，第一种方式推荐一个博主的，写的很详细，能走通，但是要的时间很长，需要下很多东西，所以我用的第二种，因为时间比较赶

ananconda+tensorflow安装：https://blog.csdn.net/weixin_37669436/article/details/71392905

anaconda+opencv安装：https://blog.csdn.net/zstarwalker/article/details/72855781

第二种首先下载python3.5.exe ：https://www.python.org/downloads/release/python-350/

记得要add python3.5.25 to path 

其他的就默认就好，完成后Win+r输入cmd 键入python查看安装版本

安装tensorflow隔了几天了有些问题可能记不清了，就写个大概的，如果大家安装遇到问题，给我留言，我会回的

第一种是pip install tensorflow 

要求是装了pip 还可能会遇到一个更新pip的问题，这个很好解决的，不知道大家能不能看懂命令行的提示，一般在一个问题出来了以后它会给你提供解决方案，按照他给的指令输入就好了，如果出现什么提交到github 这种提示，这个问题我也就解决不了了

这方式存在一个问题是安装包都是在线上下，可能出现下不下来，网络中断这样的情况

第二种 安装镜像文件，cd到镜像文件在的目录，运行镜像文件，可以下下来，也可以在线安装，我是下下来的，网址我找不到了一会儿给个百度网盘的地址分享出来吧

运行命令是 pip install *.whl

安装opencv

要装很多的包  numpy scipy, matplotlib, opencv,...

所以我装的镜像文件

我都分享到网盘里，有问题找我

网盘连接是https://pan.baidu.com/s/1815k5DT_p88FRC-gmJ-1cw  没有密码，里面是python3.5的安装包，tensorflow的镜像文件、opencv3的镜像文件

我写的可能不是很详细，不过你不会装或者安装遇到什么问题可以找我，因为在这个里面爬了一个星期，希望可以减少大家的问题

 三、python3.5+tensorflow-gpu1.3+cuda8.0+cudnn6.0

注意问题：版本对应

cuda下载地址，可选择版本

https://developer.nvidia.com/cuda-toolkit-archive

cubnn下载地址，可以选择版本，需要注册，填写问卷调查，这是正常的，

https://developer.nvidia.com/rdp/cudnn-archive

cuda安装完成以后，将cubnn压缩包里的文件放到cuda安装地址对应的包里面，即bin对应bin include对应clude  lib对应lib，拷贝文件到相应的地址

cuda默认安装的地址是 C:Program FilesNVIDIA GPU Computing ToolkitCUDA

tensorflow1.3 更新  命令

pip install --upgrade https://mirrors.tuna.tsinghua.edu.cn/tensorflow/windows/gpu/tensorflow_gpu-1.3.0rc0-cp35-cp35m-win_amd64.whl

 通过运行如下文件查看是否安装成功
