无法将数据框设置为Stata格式

问题描述

所以我正尝试将熊猫数据框转换为像这样的stata格式：

data_constr.to_stata('/Users/federiconutarelli/Desktop/First_work/PubMed/prediction_ATC/input_dummies')

data_constr

是熊猫数据框。我将第一列从对象转换为字符串，还正确地重命名了列，但是当我按下运行按钮时，它会引发错误：

<ipython-input-454-edfc671f373c> in <module>
      1 data_constr['prd'] = data_constr['prd'].astype(str)
----> 2 input_stata = data_constr.to_stata('/Users/federiconutarelli/Desktop/First_work/PubMed/prediction_ATC/input_dummies')

    565     for col in data:
--> 566         dtype = data[col].dtype
    567         # Cast from unsupported types to supported types
    568         for c_data in conversion_data:

~/anaconda3/lib/python3.7/site-packages/pandas/core/generic.py in __getattr__(self,name)
   5128             if self._info_axis._can_hold_identifiers_and_holds_name(name):
   5129                 return self[name]
-> 5130             return object.__getattribute__(self,name)
   5131 
   5132     def __setattr__(self,name: str,value) -> None:

AttributeError: 'DataFrame' object has no attribute 'dtype' ```

当我键入

for col in data:
     print(data[col].dtype) 

没有错误，所以我想知道我是否有旧版本的熊猫。 任何帮助表示赞赏。

谢谢
