windows下搭建tensorflow开发环境

1 安装cuda 10.0

https://blog.csdn.net/weixin_45023983/article/details/99178625

cuda版本跟tensorflow版本要对应。 tensorflow1.15 对应cud10

2 cuDNN下载 Download cuDNN v7.6.5 (November 18th, 2019), for CUDA 10.2

下载深度神经网络加速库。版本必须与cuda对应。

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

下载后将文件目录，拷贝到cuda安装目录：

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2\      +  cuDNN\bin..

3 安装anaconda。

https://repo.anaconda.com/archive/Anaconda3-2019.10-Windows-x86_64.exe

安装简单， 完成后cmd, 输入python  或ipython测试。

4 Anaconda下创建tensorflow环境。

参考：https://blog.csdn.net/XunCiy/article/details/89069193

Anaconda默认环境root环境下使用的是python3.7,  目前 tensorflow最新支持的python为3.6，

创建一个tensorflow的环境， 使用python版本是3.6.5

conda create --name tensorflow python=3.6.5 

安装完成后可以看到base环境下多了一个环境tensorflow

5 安装tensorflow

打开anaconda prompt命令行,请确保输入activate tensorflow后进入了tensorflow环境

安装指定GPU版本：pip install --ignore-installed --upgrade tensorflow-gpu==1.15，必须制定版本，否则安装最新版本，容易出现兼容性问题

下属对应图，实际测试，不是很准确，基本在附近。还是要实测。
