copyfile raises "FileNotFoundError: [Errno 2] No such file or directory"

Question

我想将文件复制到一个新的不存在的文件夹中：

import pandas as pd
from imutils import paths
from os import path, makedirs
from shutil import copyfile
from pathlib import Path
import os

imagePaths = list(paths.list_images('/x/x/x/x/DatasetNiiCleanedcopyB/test/NCP/'))
df= pd.read_csv(r"file.csv")

    # loop over the image paths
    for imagePath in imagePaths:
        word='/'.join(imagePath.split('/')[7:])
        #search in dataframe
        if((df['imgpath'].str.contains(word)).any()):
            imPath = Path(imagePath)
            destination_path= imPath.parent.absolute()
            output = str(destination_path).replace('DatasetNiiCleanedcopyB', 'DatasetNiiCleanedcopyB3')+'/' 
            print('source path is'+ imagePath)
            print('destination path is'+ output)   
            makedirs(path.dirname(path.abspath(output)), exist_ok=True)
            copyfile(imagePath, output)

输出：

source path is=  /x/x/x/x/DatasetNiiCleanedcopyB/test/NCP/61/1255/0065.png
    
destination path is= /x/x/x/x/DatasetNiiCleanedcopyB3/test/NCP/61/1255/

代码运行良好，但 copyfile 引发此错误：

FileNotFoundError: [Errno 2] No such file or directory: /x/x/x/x/DatasetNiiCleanedcopyB3/test/NCP/61/1255/

不知道为什么没有复制文件？

Answer 1

您打印的目标路径不是您实际传递给makedirs的路径。未创建终端子文件夹，因为您传递了 output 的 parent。但这不是必需的，因为 output 派生自 destination_path，它已经是相关文件夹的（绝对）父级。所以你真正需要的是：

makedirs(output, exist_ok=True)
