我在Windows 10上安装了Anaconda 3。我正在使用pd.read_csv（）加载csv文件，但我收到了错误消息。开始，我尝试了df = pd.read_csv('C:\direct_marketing.csv')，它工作正常，文件被导入。
然后我尝试df = pd.read_csv('C:\tutorial.csv')，收到以下错误消息：

Traceback (most recent call last):

  File "<ipython-input-3-ce208cc2684f>", line 1, in <module>
    df = pd.read_csv('C:\tutorial.csv')

    return _read(filepath_or_buffer, kwds)

OSError: File b'C:\tutorial.csv' does not exist

然后，我将文件移动到一个新文件夹中，重命名它，并再次使用read.csv（）导入它：

df = pd.read_csv('C:\Users\test.csv')

这一次我收到了不同的错误消息：

File "<ipython-input-5-03c6d380c174>", line 1
    df = pd.read_csv('C:\Users\test.csv')
                    ^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

你能帮助我了解发生了什么事以及如何处理这种情况吗？
多谢了！
