Pandas read_csv 中的错误

Question

这是我的代码：

import matplotlib.pyplot as plt
import pandas as pd
import pylab as pl
import numpy as np

df = pd.read_csv("FuelConsumption.csv")

df.head()

并且出现错误：

Traceback (most recent call last):
  File "F:/python/machine learning/regression.py", line 8, in <module>
    df = pd.read_csv("FuelConsumption.csv",engine = 'python')
  File "C:\Users\HP\AppData\Roaming\Python\Python38\site-packages\pandas\io\parsers.py", line 686, in read_csv
    return _read(filepath_or_buffer, kwds)

    f = open(path_or_buf, mode, errors="replace", newline="")
FileNotFoundError: [Errno 2] No such file or directory: 'FuelConsumption.csv'

我确定我已经下载了 csv，但它仍然无法工作 任何人都可以帮助我吗？

Answer 1

文件路径是 read_csv 方法的主要参数。 你应该指定csv文件的路径，如果python文件和csv文件不在同一个目录下，你可以使用相对或绝对路径。

Answer 2

您应该知道您的工作区和您的 CSV 文件位于同一目录中。

Answer 3

我认为你应该把你的 file.csv 和 .py 放在同一个文件夹中。
