python - pandas出毛病了，重装也不行

Question

Traceback (most recent call last):
  File "C:\Users\Administrator\AppData\Roaming\Python\Python36\site-packages\pandas\indexes\base.py", line 2134, in get_loc

During handling of the above exception, another exception occurred:

这个错误我也是一脸懵，安装各种依赖库，卸载重装都不行，求大神指导

Answer 1

推荐使用Python的发行版Anaconda，自带各种数据处理包，不用额外安装
该发行版使用conda包管理工具，可以有效避免pip安装导致的依赖错误，无法安装等问题
如果觉得安装包比较大，可以试用精简版的Miniconda,需要额外下载安装。

如果使用conda下载速度比较慢，可以使用清华的镜像，清华conda镜像配置
