Question

我正在尝试将Excel文件读取到Pandas数据框中并绘制2列。我的代码如下：

import numpy as np
import pandas as pd
from pylab import plt
plt.style.use('seaborn')

data1 = pd.read_excel('LogReturns_AAPL.xlsx')
data1[['Returns', 'log_returns']].cumsum().apply(np.exp).plot(figsize=(10, 6))

但是我一直收到此错误：

FileNotFoundError: [WinError 2] The system cannot find the file specified

<Figure size 720x432 with 1 Axes>

（很长）回溯的一部分如下：

     Error in callback <function install_repl_displayhook.<locals>.post_execute at 0x0000022E1842F158> (for post_execute):
Traceback (most recent call last):
File "C:\Users\DELL\Anaconda3\lib\subprocess.py", line 395, in check_output
        **kwargs).stdout

      File "C:\Users\DELL\Anaconda3\lib\subprocess.py", line 472, in run
        with Popen(*popenargs, **kwargs) as process:

      File "C:\Users\DELL\Anaconda3\lib\site-packages\spyder_kernels\customize\spydercustomize.py", line 143, in __init__
        super(SubprocessPopen, self).__init__(*args, **kwargs)

      File "C:\Users\DELL\Anaconda3\lib\subprocess.py", line 775, in __init__
        restore_signals, start_new_session)

      File "C:\Users\DELL\Anaconda3\lib\subprocess.py", line 1178, in _execute_child
        startupinfo)

请让我知道我应该做些什么。谢谢！

Edit1：以下是Python脚本pwd的结果：

'C:\\Users\\DELL\\Desktop'

Answer 1

我认为您的问题与文件路径有关。因此，请尝试此

df = pd.read_excel(r'C:/Users/DELL/Desktop/LogReturns_AAPL.xlsx')

这会将熊猫引导到绝对路径。可能正是您需要的。
