Question

我正在尝试将此zip file后面的.dta文件加载到pandas。但是，我立即收到错误。我的命令也有stata，但由于错误信息没有告诉我更多信息，比如故障列，我不知道该怎么做。

如何将文件加载到pandas？

>>> df = pd.read_stata('cepr_org_2014.dta')

Traceback (most recent call last):
  File "<input>", line 1, in <module>

ValueError: Categorical categories must be unique

Answer 1

使用pandas.read_stata('cepr_org_2014.dta', convert_categoricals=False, convert_missing=True)加载此内容并查看数据的外观。（可选）使用ipdb进行调试，如问题中所述，显示数据中存在重复的类别。

加载STATA文件：分类值必须是唯一的
