Question

我需要以下帮助：

我试图将一个csv文件导入到Jupyter笔记本中，但无济于事。

我使用的代码是：

dfa = pd.read_csv（'Filename.csv'）

并给出以下错误消息：

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

我已经检查了文件是否从同一文件夹中打开，并且它们都存储在我的桌面中。

我安装了熊猫，matplotlib和seaborn。我已经尝试了所有方法（Stackoverflow的其他解决方案），但无法弄清楚为什么我无法导入。请赐教。谢谢！

@jpp： Another csv file was able to work 这很奇怪，因为我尝试使用另一个csv文件并且它起作用了。我无法加载这些文件。

我不太确定它是否与Mac中的文件或设置有关。谢谢！

Answer 1

您应该考虑使用pd.read_csv可用的参数。例如，您可以指定分隔符并跳过行。您在末尾有一个空列，在底部有一个垃圾，但这可以在读取文件后处理。

例如：

Failed to clear cache. Make sure you have the proper permissions.

Answer 2

您可以跳过坏行（字段数不匹配）：

dfa = pd.read_csv('Filename.csv',error_bad_lines=False)

使用熊猫将CSV文件导入Jupyter Notebook
