tensorflow 安装问题

配好anaconda, cuDNN, cuda之后，用pip安装TensorFlow之后出现以下问题

>>> import tensorflow
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

网上说是缺少Microsoft visual C++ 2015 redistributable(x64)，在控制面板中查看安装的软件

已安装的

果然没有2015版本的，于是去官网下载了
但是安装出现错误，经过百度得知是因为安装了更高版本的Microsoft Visual C++ 所以才出现这种情况。于是卸载2017版本，再次安装成功。
测试后仍然失败
