 在运行代码的时候控制台出现 RuntimeWarning 警告, 但是程序并没有终止运行:

numpy.dtype size changed, may indicate binary incompatibility

由该信息可以想到, 在安装 pandas 模块的时候, 一同安装了 numpy, 可能是 numpy 模块的原因, 重新安装 numpy 并不起作用

解决办法:

查阅了@独孤呆博的博客, 是由于 numpy 和 pandas 不兼容, 卸载高版本 numpy, 重装低版本

E:\练习>pip uninstall numpy
Uninstalling numpy-1.15.0:
  Would remove:
    c:\users\lvcha\appdata\local\programs\python\python35-32\lib\site-packages\numpy-1.15.0.dist-info\*

再次运行代码, 问题不再重现:
