Windows10中安装tensorflow-cpu为tensorflow-gpu、CUDA、cuDNN

windows+CUDA9.0+cuDNN9.0即可

一、安装CUDA
1.准备好NVIDIA的显卡，下载安装CUDA
https://developer.nvidia.com/cuda-downloads
2.安装好之后把CUDA安装目录下的bin和lib\x64添加到

Path环境变量中

二、安装cuDNN
1.cuDNN下载
https://developer.nvidia.com/rdp/cudnn-download
2.解压压缩包，把压缩包中bin,include,lib中的文件
分别拷贝到C:\Program Files\NVIDIA GPU Computing
Toolkit\CUDA\v9.0目录下对应目录中
3.把C:\Program Files\NVIDIA GPU Computing
Toolkit\CUDA\v9.0\extras\CUPTI\libx64\cupti64_90.dll
拷贝到C:\Program Files\NVIDIA GPU Computing
Toolkit\CUDA\v9.0\bin

三、安装tensorflow-gpu
1.pip uninstall tensorflow
2.pip install tensorflow-gpu

四、最后在python中测试

import tensorflow as tf
a = tf.constant([1.,2.,3.,4.,5.,6.], shape=[2,3], name='a')
b = tf.constant([1.,2.,3.,4.,5.,6.], shape=[3,2], name='b')
c = tf.matmul(a,b)

with tf.Session(config= tf.ConfigProto(log_device_placement=True)) as sess:

    print(sess.run(c))

得到结果截图如下，包含了gpu信息即安装成功

   ...: a = tf.constant([1.,2.,3.,4.,5.,6.], shape=[2,3], name='a')
   ...: b = tf.constant([1.,2.,3.,4.,5.,6.], shape=[3,2], name='b')
   ...: c = tf.matmul(a,b)
   ...:
   ...: with tf.Session(config= tf.ConfigProto(log_device_placement=True)) as sess:
   ...:     print(sess.run(c))
