我的代码中出现以下错误。Confirmed_India、recovered_India、deaths_India 是包含电晕病例的预定义数据集的表列表。代码：

confirmed_India_ts = confirmed_df[confirmed_df['Country/Region'] == "India"]

confirmed_India_ts = confirmed_India_ts.drop(
['Lat','Long','Country/Region','Province/State'],axis=1).reset_index(drop=True).sum()

deaths_India_ts = deaths_df[deaths_df['Country/Region'] == "India"]

confirmed_India_ts = deaths_India_ts.drop(
['Lat','Long','Country/Region','Province/State'],axis=1).reset_index(drop=True).sum()

recovered_India_ts = recovered_df[recovered_df['Country/Region'] == "India"]

recovered_India_ts = deaths_India_ts.drop(
['Lat','Long','Country/Region','Province/State'],axis=1).reset_index(drop=True).sum()

active_India_ts = pd.Series(
    data = np.array(
            
[(x1 - x2 - x3) for (x1, x2, x3) in zip(
                confirmed_India_ts.values, deaths_India_ts.values, 

recovered_India_ts.values)
               
 ]
                
        ),
        index = confirmed_India_ts.index
)





error:

此错误表明您正在尝试减去 Integer 类型和 String 类型。因此，我建议您在执行 (x1 - x2 - x3) 操作之前检查每个 x1、2、3 RIGHT 的数据类型。也许您在预处理过程中弄乱了其中一种类型。例如。x1 是 Int 类型，但 x2 是字符串。

请提供更多信息，以便我可以帮助您。
