装了两天，系统重装一四次，软件安装卸载无数次，终于装好。

版本

软件版本

安装顺序

1.安装Python环境，并且勾上 Add Python to environment variables这个选项。

2.安装cuda和cudnn

将cudnn中的数据包复制到cuda对应的路径。如果报错缺少cu
ddn65-7.ddl就是没有将cudnn中的数据包复制的原因。

3.安装tensorflow：在cmd中输入指令pip install tensorflow-gpu

4.安装Pycharm,常规安装就行，没有什么特别注意的地方。

5.安装VS2015,如果不安装会报错找不到mvs4p.dll

6.在Pycharm新建Python项目，将下面的代码复制进项目运行，查看结果是否有异常及报错。

代码1：

import tensorflow as tf
a = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[2, 3], name='a')
b = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[3, 2], name='b')
c = tf.matmul(a, b)
sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))
print(sess.run(c))

代码运行结果
