这是我的代码:

然后出现了以下错误:

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)  File "C:\Users\HP\AppData\Roaming\Python\Python38\site-packages\pandas\io\parsers.py", line 452, in _read    parser = TextFileReader(fp_or_buf, **kwds)  File "C:\Users\HP\AppData\Roaming\Python\Python38\site-packages\pandas\io\parsers.py", line 946, in __init__    self._make_engine(self.engine)  File "C:\Users\HP\AppData\Roaming\Python\Python38\site-packages\pandas\io\parsers.py", line 1189, in _make_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'

我确定已经下载了csv文件，但还是无法工作。有人能帮帮我吗？

回答：

文件路径是read_csv方法的主要参数。你需要指定csv文件的路径，如果Python文件和csv文件不在同一个目录下，你可以使用相对路径或绝对路径。
