Pandas read_csv 中的錯誤

Question

這是我的代碼：

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()

並且出現錯誤：

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)
  File "C:\Users\HP\AppData\Roaming\Python\Python38\site-packages\pandas\io\parsers.py", line 452, in _read
    parser = TextFileReader(fp_or_buf, **kwds)

    self._make_engine(self.engine)

    self._engine = klass(self.f, **self.options)
  File "C:\Users\HP\AppData\Roaming\Python\Python38\site-packages\pandas\io\parsers.py", line 2382, in __init__
    f, handles = get_handle(
  File "C:\Users\HP\AppData\Roaming\Python\Python38\site-packages\pandas\io\common.py", line 496, in get_handle
    f = open(path_or_buf, mode, errors="replace", newline="")
FileNotFoundError: [Errno 2] No such file or directory: 'FuelConsumption.csv'

我確定我已經下載了 csv，但它仍然無法工作 任何人都可以幫助我嗎？

Answer 1

文件路徑是 read_csv 方法的主要參數。 你應該指定csv文件的路徑，如果python文件和csv文件不在同一個目錄下，你可以使用相對或絕對路徑。

Answer 2

您應該知道您的工作區和您的 CSV 文件位於同一目錄中。

Answer 3

我認為你應該把你的 file.csv 和 .py 放在同一個文件夾中。
