RuntimeWarning: numpy.dtype size changed, may indicate binary incompatibility

安装Numpy遇到问题解决

1. 问题描述

  在安装tensorflow的过程中import tensorflow出现了如下问题

2. 分析问题

  在上面的报错中可以看到，问题主要集中在两个部分，一个部分是scipy，另一个部分是numpy。通过下载重装scipy并没有解决问题，而且如下图所示，在 PyPI 上scipy最近并没有更新

  因此需要考虑是否是numpy造成的问题，在 PyPI 上看到

看到在22小时之前刚刚发布了新的版本（1.15.0rc1），然后又查了一下自己的版本，果然就是这版

3. 总结原因

  所以造成这个问题产生的原因很简单，就是各种库之间的版本不匹配，只需要把numpy的版本降到1.14.5就可以了

4. 具体操作

sudo pip uninstall numpy
sudo pip install numpy==1.14.5

问题完美解决!
