tensorflow1.3.0安装注意

环境：win10 python3.5

使用pip安装：

python -m pip install --upgrade pip

python -m pip install --upgrade tensorflow-gpu

安装成功后却不能使用，错误如下：

>>> import tensorflow as tf

解决方案：

该问题是因为cuDNN版本不匹配导致，从https://developer.nvidia.com/rdp/cudnn-download下载cudnn-8.0-windows10-x64-v6.0.zip，解压出cudnn64_6.dll，放到系统PTAH搜索路径下。如果之前装过tensorflow1.2.0的，直接覆盖之前的即可。
