so setup, have installed anaconda distrib of ipython, pyzmq & tornado libraries. have created profile nbserver , config file follows - 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 don't know clues anymore - , i'm lacking greater understanding of how works figure out. ultimate goal use answer this question on complete setup behind apache , connect colaboratory - seems should launch first.

many :)

this should fix issue:

pip install jupyter
