我已經定義了一個函數，用以前由 LabelEncoder 生成的變量替換數組中的變量。我讓它適用于一維數組，但我現在想讓它適用于帶有 for 循環的多維數組。但是 for 循環似乎沒有按照我預期的方式遍歷行。我認為這是一個簡單的錯誤，但我們將不勝感激任何建議。這是我當前的代碼：def new_data (i):    for x in i:        x[0] = np.where(x[0] =='40-49', 2, x[0])        x[0] = np.where(x[0] == '50-59', 3, x[0])       #Etc for each item        prediction = classifier.predict([[x]])        prediction1 = np.where(prediction > 0.6, 1, prediction)        prediction1 = np.where(prediction <= 0.6, 0, prediction)        if prediction1 == 0:            return 'Prediction: No recurrence-events, with a confidence of: ' + str(prediction)        else:            return 'Prediction: Recurrence-events, with a confidence of: ' + str(prediction)輸入將是：new_predict = np.array(['40-49', 'ge40', '25-29', '6-8'],                        ['40-49', 'ge40', '25-29', '6-8'],                        ['40-49', 'ge40', '25-29', '6-8'])new_data(new_predict)然后我希望有一個輸出，例如：Prediction: No recurrence-events, with a confidence of: [prediction]Prediction: No recurrence-events, with a confidence of: [prediction]Prediction: No recurrence-events, with a confidence of: [prediction]其中每個預測都與數組中的一行相關。但我目前只收到類型錯誤，而不是遍歷數組的組件。Traceback (most recent call last):  File "/Users/Tom/MSc Project/venv/lib/python3.8/site-packages/IPython/core/interactiveshell.py", line 3331, in run_code    exec(code_obj, self.user_global_ns, self.user_ns)  File "<ipython-input-19-fcc97a6a2285>", line 1, in <module>    new_predict = np.array(['40-49', 'ge40', '25-29', '6-8', 'yes', 2, 'right', 'right_up', 'no'],['40-49', 'ge40', '25-29', '6-8', 'yes', 2, 'right', 'right_up', 'no']TypeError: data type not understood
