jupyter无法下载文件夹，在要下载的文件夹下新建一个notebook。

复制如下代码：

#jupyter下载文件夹
import os
import tarfile

def recursive_files(dir_name='.', ignore=None):
    for dir_name,subdirs,files in os.walk(dir_name):
        if ignore and os.path.basename(dir_name) in ignore: 
            continue

        for file_name in files:
            if ignore and file_name in ignore:
                continue
            if '.pkl' in file_name:
                continue
            yield os.path.join(dir_name, file_name)

def make_tar_file(dir_name='.', tar_file_name='tarfile.tar', ignore=None):
    tar = tarfile.open(tar_file_name, 'w')
    for file_name in recursive_files(dir_name, ignore):
        tar.add(file_name)
    tar.close()

dir_name = '.'
tar_file_name = 'download.tar'
ignore = {'.ipynb', '__pycache__', tar_file_name}
make_tar_file(dir_name, tar_file_name, ignore)

 

运行notebook，即可得到名为“download.tar”的压缩包，下载压缩包即可
