使用 python 在 Jupyter 实验室中找不到文件错误

Question

我使用在线jupyterlab which can be accessed through this link below if not then use the second link

This is the second link

所以问题是我已将 .csv 格式文件上传到实验室，但当我尝试使用此代码加载它时

import pandas as pd
import matplotlib.pyplot as plt
from collections import Counter
import seaborn as sns

df = pd.read_csv ('demo/big.csv')

print(df)

它给了我以下错误

FileNotFoundError                         Traceback (most recent call last)

请帮我看看我给的路径不正确还是这里有什么问题？

您应该检查并确保您的笔记本与您尝试导入的文件位于同一目录中。因此，如果笔记本位于桌面上名为“Notebooks”的文件夹中，则将数据放在该文件夹中。然后，确保

df = pd.read_csv ('demo/big.csv')

您的代码部分只有文件名和 .csv 结尾。如果文件被命名为 big.csv，那么它应该是

df = pd.read_csv ('big.csv') 

这些是您收到该错误的主要原因。
