Numpy版本问题，import tensorflow as tf 报警：“ FutureWarning: Passing (type, 1) or '1type' as a synonym of type is deprecated; in a future version of numpy, it will be understood as (type, (1,)) / '(1,)type'”

tensorflow cpu版，成功安装后

import tensorflow as tf 报警：“ FutureWarning: Passing (type, 1) or '1type' as a synonym of type is deprecated; in a future version of numpy, it will be understood as (type, (1,)) / '(1,)type'”

 可能原因：numpy 的版本过低或者过高都会出现警告

 解决：先卸载现有的numpy版本，并重新指定安装1.16.4（我的anaconda最新版本）版本的numpy

pip uninstall numpy

pip install numpy==1.16.4

默认镜像出现下载安装错误

 于是更换镜像源再安装

  pip install numpy==1.16.4 -i  https://pypi.tuna.tsinghua.edu.cn/simple/

输入测试后不再报错
