If you want feature names to be stored and validated, you must convert them all to strings, by using X.columns = X.columns.astype(str) for example. Otherwise you can remove feature / column names from your input data, or convert them all to a non-string data type.

这是一个Python程序的错误提示，大概意思是特征名只支持字符串类型，但输入的特征名包含了int和str类型。如果您想要存储并验证特征名，您需要将所有特征名转换为字符串类型，例如使用X.columns = X.columns.astype(str)。否则，您可以从输入数据中删除特征/列名，或将它们全部转换为非字符串数据类型。建议您检查一下代码中的特征名的数据类型是否正确。
