如何使用python保存多個SVM模型我正在嘗試通過使用 for 循環范圍從列表中獲取名稱來保存多個模型以保存在路徑中。我的模型工作正常，但在嘗試以唯一名稱保存每個模型時出現錯誤。city_id = ['1', '2', '18', '19', '21', '23', '26', '27', '28', '32', '35', '36', '37', '38', '39', '40', '41',       '42', '43', '44', '45', '46', '47', '49', '50', '51', '58', '65', '67', '68', '69', '70', '71']for i in range(len(city_id)):    joblib.dump(model, 'D:/Model/model_Predict_Locality_predictor_'+ str(city_id[i]) +'.pkl', compress=1)但是out of range error我也有檢查范圍，但兩個范圍都相同。錯誤1Model Pipeline Created Successfully...Data fitted Successfully...Data Predicted Successfully...Accuracy: 0.9908892595919415list index out of range2Model Pipeline Created Successfully...Data fitted Successfully...Data Predicted Successfully...Accuracy: 0.9790685504971219list index out of range準確后，得到如上的錯誤。
