Question

我正在尝试修复错误，该如何使我的数据集能够被jupyter Notebook读取，但始终显示一些错误。与长消息框。此外，同样，我尝试查看jupyter笔记本是否存在任何问题，但是当我尝试读取少量数据时，它很容易读取。以下我已告知我所有信息，请帮助。谢谢

df = pd.read_csv ("C:/Users/patel/Desktop/tap.csv")
print (df.head())

This is my trail for a small dataset which shows the path and all is okay. but I don't know what's wrong?



df = pd.read_csv("C:/Users/patel/Desktop/season-0809_csv.csv", header = 0)
print (df.head())

Answer 1

该错误表明找不到该文件：

FileNotFoundError：[错误2]文件b'C：/Users/patel/Desktop/tap.csv'不存在：b'C：/Users/patel/Desktop/tap.csv'

因此，如果您使用的是Windows，请确保按以下方式指定文件的路径：

CSV_FILE = "C:\\Users\\patel\\Desktop\\tap.csv"
df = pd.read_csv(CSV_FILE)
