Я пытаюсь заставить работать локальную среду выполнения Google Colb, но когда я пытаюсь подключиться к локальному серверу, я получаю:
[I 10:17:23.142 NotebookApp] Serving notebooks from local directory: /home/adam/Documents/PYTHON/Complexity_Challenge/Spring_2018

[W 10:17:33.609 NotebookApp] 404 GET /http_over_websocket (127.0.0.1) 50.27ms referer=None
404 GET находится на последней строке. Я изменил настройку в jupyter_notebook_config.py, как указано в https://research.google.com/colaboratory/local-runtimes.html
РЕДАКТИРОВАТЬ: после комментариев Боба я установил пакет, а затем открыл записную книжку и попытался подключиться. Это все еще не работало, но сообщение об ошибке другое:
