python-3.4 中的 UnicodeDecodeError

Question

我在 Jupyter Notebook 中使用 Python (3.4)，默认情况下应该已经使用 utf-8。但是从 csv 文件中读取一些数据时出现以下错误。知道如何解决这个问题吗？谢谢！

从 csv 文件中读取的代码：

with open('my_data.csv') as csvfile:
    line = csv.reader(csvfile)

    for row in line:
        print (row)

错误：

打开文件时指定编码。同样根据csv module documentation 使用newline='' 选项作为要包装的文件：

with open('my_data.csv',encoding='utf8',newline='') as csvfile:
    line = csv.reader(csvfile)
