Python 无法将数据帧转换为stata格式

因此，我尝试将pandas数据帧转换为stata格式，如下所示：

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

data_constr

是一个数据帧。我将第一列从object转换为string，并正确重命名了列，但当我点击run按钮时，它会引发一个错误：

<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')

没有错误产生，所以我想知道我是否有熊猫的旧版本。 感谢您的帮助

谢谢,

我也遇到过这个问题。我认为这与有关，不过你必须找出哪些列是导致你失败的原因。我也遇到过这个问题。我认为这与相关，不过您必须找到导致您失败的列。

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