刚安装好tensorflow安装包去试试import tensorflow as ft时，出现错误。
错误原因：
ImportError: Could not find the DLL(s) ‘msvcp140_1.dll’. TensorFlow requires that these DLLs be installed in a directory that is named in your %PATH% environment variable.
解决办法：
1、打开这个网站
https://support.microsoft.com/zh-cn/help/2977003/the-latest-supported-visual-c-downloads
2、在这里下载vc_redist64.exe文件。
3、下载后双击安装，然后重启就行了。再次运行import tensorflow as tf就不会报错了。
