win7下cuda8.0安装跑gpu版tensorflow

要用深度学习做目标检测，先尝试了caffe，这会又要熟悉tensorflow了，简单写下配置过程吧，挺简单的：

0.win7 X64系统

1.安装vs2013

2.安装Anaconda3(需要里面的python环境）

3.下载CUDA8.0(https://developer.nvidia.com/cuda-downloads),下面两个exe文件都下载

补充说明：我电脑里原来是cuda7.5,故需要先卸载干净，我是这么做的，有需要的可以借鉴：

(1)把下图中的前5项用电脑管家全部卸载干净(图形驱动程序不需要卸载）

(2)删除C:\Program Files\NVIDIA GPU Computing Toolkit 文件夹

删除 C:\ProgramData\NVIDIA GPU Computing Toolkit 文件夹

删除C:\ProgramData\NVIDIA Corporation\CUDA Samples 文件夹

4.运行exe（注，若电脑上已经有了最新的显卡驱动程序，可以不用去装图形显卡驱动程序）

默认下一步到最后

5.再运行exe

默认下一步到最后

6.下载cuddn5.1(如果想要了解cuddn和cuda的区别可以看该博客http://blog.csdn.net/fangjin_kl/article/details/53906874

7.解压cuddn5.1，把如下的三个文件夹替换到C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0夹下（该目录是我的cuda8.0的安装目录）

这里需要在系统变量里设置下面几个变量：

CUDA_PATH： C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0

CUDA_BIN_PATH： C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\bin

CUDA_LIB_PATH： C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\lib\x64

CUDA_PATH_V8_0： C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0

CUDA_SDK_BIN_PATH： C:\ProgramData\NVIDIA Corporation\CUDA Samples\v8.0\bin\win64

CUDA_SDK_LIB_PATH： C:\ProgramData\NVIDIA Corporation\CUDA Samples\v8.0\common\lib\x64

CUDA_SDK_PATH： C:\ProgramData\NVIDIA Corporation\CUDA Samples\v8.0

8.查看cuda8.0是否安装成功，可以在CMD窗口下敲指令nvcc -V

9.再运行一个Sample例子打开C:\ProgramData\NVIDIA Corporation\CUDA Samples\v8.0\1_Utilities\deviceQuery解决方案，编译下，出来的结果为

补充说明：到这说明cuda的环境基本配好了，该笔记本也是支持GPU加速的，可以玩tensorflow gpu版的了

中间我报过这个问题，发现是我的显卡驱动被卸载了，设备管理器找不到了

10.pip安装tensorflow gpu库（http://blog.csdn.net/u014365862/article/details/53868578）

在Anaconda Prompt里输入（不是cmd跳出的窗口内输入） pip install tensorflow-gpu==1.2.0（如果直接不加版本限制，会是最新版，此时可能和你的cuda版本有冲突，而报错，所以做好加上版本控制）

11.安装完后输入import tensorflow试试

13.我的独立显卡是

NVIDIA GeForce 830M, 是可以支持GPU加速的（大家有配不了的时候，别着急，好好分析下原因）

14.提醒下：

显卡驱动请用驱动精灵升级到最新版，不然可能会报如下错误： CUDA driver version is insufficient for CUDA runtime version

15.打开Pycharm，输入

# python 3.5.3 import tensorflow as tf a = tf.constant([1.0, 2.0, 3.0], shape=[3], name='a') b = tf.constant([1.0, 2.0, 3.0], shape=[3], name='b') c = a + b sess = tf.Session(config = tf.ConfigProto(log_device_placement=True)) print(sess.run(c))

结果：

"C:\Program Files\Anaconda3\python.exe" C:/Users/icecream.shao/Desktop/tensorflow-fcn-master1/ceshi.py
