Question

我正在尝试执行显示特定路径的文件格式的代码。

但是我收到了与指定路径相关的以下错误。在'C：\ Research \ LungCancerDetaction \ Preprocessing2.py'文件夹中执行的文件。

'input'文件夹位于路径C：\ Research \ input。

以下是编写的代码。

    import numpy as np # Linear algebra
    import pandas as pd # Data processing, CSV file I/O (e.g. pd.read_csv)
    import skimage, os
    from skimage.morphology import ball, disk, dilation, binary_erosion, remove_small_objects, erosion, closing, reconstruction, binary_closing
    from skimage.measure import label,regionprops, perimeter
    from skimage.morphology import binary_dilation, binary_opening
    from skimage.filters import roberts, sobel
    from skimage import measure, feature
    from skimage.segmentation import clear_border
    from skimage import data
    from scipy import ndimage as ndi
    import matplotlib.pyplot as plt
    from mpl_toolkits.mplot3d.art3d import Poly3DCollection
    import dicom
    import scipy.misc
    import numpy as np

    # Input data files are available in the "../input/" directory.
    # For example, running this (by clicking run or pressing Shift+Enter) will list the files in the input directory

    import subprocess
    print(subprocess.check_output(["ls", "../input"]).decode("utf8"))

但是我收到了错误，

    Traceback (most recent call last):
      File "C:/Research/LungCancerDetaction/Preprocessing2.py", line 22, in <module>
        print(subprocess.check_output(["ls", "../input"]).decode("utf8"))
      File "C:\Research\Python_installation\lib\subprocess.py", line 626, in check_output
        **kwargs).stdout
      File "C:\Research\Python_installation\lib\subprocess.py", line 693, in run
        with Popen(*popenargs, **kwargs) as process:
      File "C:\Research\Python_installation\lib\subprocess.py", line 947, in __init__
        restore_signals, start_new_session)
      File "C:\Research\Python_installation\lib\subprocess.py", line 1224, in _execute_child
        startupinfo)
    FileNotFoundError: [WinError 2] The system cannot find the file specified

如何找出错误？

Answer 1

删除此行...

print(subprocess.check_output(["ls", "../input"]).decode("utf8"))

...而是使用它：

import os

print(os.listdir('../input'))

尝试列出路径中的文件夹时，Python中的check_output错误
