報錯：AttributeError: '_csv.reader' object has no attribute 'next'

原因：python版本問題

解決：將headers = reader.next()改為headers = next(reader)

報錯：_csv.Error: iterator should return strings, not bytes (did you open the file in text mode?)

原因：python版本問題

解決：將allElectronicsData = open(r'F:/txt/AllElectronics.csv', 'rb')改成allElectronicsData = open(r'F:/txt/AllElectronics.csv', 'rt')

報錯：ValueError: Expected 2D array, got 1D array instead

原因：資料維度不對，將其通過reshape進行轉化

解決：將predictedY = clf.predict(newRowX)改成predictedY = clf.predict(newRowX.reshape(1,-1))
