這篇文章主要介紹了Jupyter 無(wú)法下載文件夾如何實(shí)現(xiàn)曲線救國(guó)？今天小編就為大家?guī)?lái)了解決方法，希望對(duì)大家有所幫助。一起跟隨小編過(guò)來(lái)看看吧

原問(wèn)題：

https://stackoverflow.com/questions/48122744/how-to-download-all-files-and-folder-hierarchy-from-jupyter-notebook/48141707

解決方法是：

1. 找到你想下載的文件夾

2. 打開(kāi)文件夾，新建一個(gè)ipynb

3. 粘貼下面代碼并運(yùn)行

4. 回到文件夾，刷新，看到多了個(gè)archive.tar的壓縮文件，下載這個(gè)文件解壓就行。

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

   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 = 'archive.tar'
ignore = {'.ipynb_checkpoints', '__pycache__', tar_file_name}
make_tar_file(dir_name, tar_file_name, ignore)

補(bǔ)充知識(shí)：Jupyter安裝拓展nbextensions及解決官網(wǎng)下載慢的問(wèn)題

Anaconda Jupyter安裝拓展nbextensions

先在終端pip兩個(gè)包：

Pip install jupyter_contrib_nbextensions

Pip install jupyter_nbextensions_configurator

安裝成功后

Jupyter contrib nbextension install --user

Pip install jupyter_contrib_nbextensions
Pip install jupyter_nbextensions_configurator
Jupyter contrib nbextension install --user

使用豆瓣鏡像：

但是直接這樣pip下載很慢，簡(jiǎn)直慢到懷疑人生，下載了半天還下載失敗了/(ㄒoㄒ)//(ㄒoㄒ)/

所以我們可以使用豆瓣鏡像，即在后面加 -i https://pypi.douban.com/simple

這個(gè)堪稱神器呀，下載的時(shí)候刷刷的O(∩_∩)O

Pip install jupyter_contrib_nbextensions -i https://pypi.douban.com/simple
Pip install jupyter_nbextensions_configurator -i https://pypi.douban.com/simple

后面操作不變：

Jupyter contrib nbextension install --user

Pip install jupyter_contrib_nbextensions -i https://pypi.douban.com/simple
Pip install jupyter_nbextensions_configurator -i https://pypi.douban.com/simple
Jupyter contrib nbextension install --user
