Question

Error message我正在尝试在Jupyter Notebooks上上传CSV文件，并且尝试使用本文中的解决方案：

Why do I get a SyntaxError for a Unicode escape in my file path?

还有其他几篇文章提出了相同的建议。

当我尝试第一个建议时，出现此错误：

FileNotFoundError: [Errno 2] File b'C:\\Users\\Naveed\\Desktop\\RateStats.csv' does not exist: b'C:\\Users\\Naveed\\Desktop\\RateStats.csv'

但是，它仍然无法正常工作。我不确定通过labs.cognitiveclass.ai使用Jupyter的事实是否与它有关，但是我认为这不是问题。我在计算机上安装的Jupyter上进行了尝试，但仍然无法上传CSV。

感谢您的帮助。谢谢！

我希望至少能够输出前几行数据，而不是错误消息。

Answer 1

您需要尝试以下操作：

df = pd.read_csv('C:\\Users\\Naveed\\Desktop\\RateStats.csv')

或

df = pd.read_csv('C:/Users/Naveed/Desktop/RateStats.csv')

问题是因为当您尝试使用时

'C:\Users

\U是一个Unicode转义字符。

如果这是一个找不到文件的错误，则需要确保在给定路径中存在RateStats文件。

Answer 2

这将为您提供输出

df = pd.read_csv（'C：\\ Users \\ Naveed \\ Desktop \\ RateStats.csv'）。head（）

尽管尝试了各种解决方案，Jupyter Notebook也没有上传CSV文件
