我在将 CSV 文件读入 Jupyter Notebook 时遇到问题。这是代码：

import pandas as pd
mpg = pd.read_csv('C:/Users/Ajibola/Documents/mpg.csv')
mpg.head()

这是我得到的错误：

File "<ipython-input-138-844bace16611>", line 1
    mpg = pd.read_csv('C:\Users\Ajibola\Documents\mpg.csv')
                     ^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

在 PATH 加上 r 前缀后，我得到了错误：

---------------------------------------------------------------------------
