我正在尝试将zip file之后的.dta文件加载到熊猫中.但是,我立即得到一个错误.我的命令中也有stata,但是由于错误消息没有告诉我更多信息,例如错误的列,所以我不知道该怎么做.
如何将文件加载到熊猫中？
>>> df = pd.read_stata('cepr_org_2014.dta')

ValueError: Categorical categories must be unique
解决方法:
使用pandas.read_stata(‘cepr_org_2014.dta’,convert_categoricals = False,convert_missing = True)加载它,并查看数据的外观.
如问题中所述,可以选择使用ipdb进行调试,以表明您的数据中存在重复的类别.
