ipython 서버를 시작할 수 없음 : notebook.notebookapp라는 모듈이 없습니다.

ipython 서버를 시작할 수 없음 : notebook.notebookapp라는 모듈이 없습니다.

---

나는 몇 가지 튜토리얼을 따라 ipython 서버를 설정하려고 시도했습니다 (정확히 내 경우가 아니기 때문에). 며칠 전, 나는 그것이 시작되는 지점까지 그것을 관리했지만 URL을 통해 액세스 할 수 없었습니다. 오늘은 더 이상 시작되지 않으며이 특정 오류에 대해 많이 찾을 수 없습니다.

그래서 설정에 대해 ipython, pyzmq 및 tornado 라이브러리의 anaconda distrib을 설치했습니다. 프로필 nbserver를 만들었고 구성 파일은 다음과 같습니다-ipython.config.py :

c = get_config()
c.IPKernalApp.pylab = 'inline'
c.NotebookApp.certfile = u'/home/ludo/.ipython/profile_nbserver/mycert.pem'
c.NotebookApp.ip = '*'
c.NotebookApp.open_browser = False
c.NotebookApp.password = u'sha1:e6cb2aa9a[...]'
c.NotebookApp.port = 9999
c.NotebookManager.notebook_dir = u'/var/www/ipynb/'
c.NotebookApp.base_project_url = '/ipynb/'
c.NotebookApp.base_kernel_url = '/ipynb/'
c.NotebookApp.webapp_settings = {'static_url_prefix':'/ipynb/static/'}

I really don't know where to look for clues anymore - and I'm probably lacking a greater understanding of how all this works to figure it out. My ultimate goal is to then use the answer to this question on SO to complete a setup behind apache and eventually connect it to colaboratory - but seems like it should launch first.

Many thanks for any help :)

This should fix the issue:

pip install jupyter

I received the same problem when upgrading IPython. At the moment the answer was written, it was a bug linked to the latest 4 version. If a similar problem occurs for which you wish to switch back to the stable version 3.2.1:

pip uninstall -y IPython
pip install ipython==3.2.1

• note: the -y option indicates "yes I want to uninstall" with no interaction.
• note 2: possible duplicate in ImportError: No module named notebook.notebookapp

So to close this thread, and in case it helps anyone, my mistake was to have installed and used the dev version of ipython blindly following a tutorial, thinking I was using the anaconda instance I installed earlier (which was not even in my PATH).

Anyhow I:

• uninstalled that ipython dev instance
• added anaconda/bin to my zsh path (add it to ~/.zshrc - that's why it was not even in my path after install) // at this point the server was launching fine but I couldn't access it in my browser >> firewall problems.
• opened my port of choice in my firewall (help for linode or ubuntu in general)

And everything works fine now.

Someone mentioned this in a comment, and it (almost) worked for me:

pip install ipython[notebook]

pip gave an error about the hash not matching. However, what ultimately worked was:

sudo port install py27-notebook

And for py3:

sudo port install py35-notebook

You should not try to install from github master branch if you do not now what you are doing. Remove what you have installed and stick to stable version.

If you want to work on developpement version, ask on the developpement mailing-list. Some knowlege on how to debug this will probably be required.
