> Setup instructions
> In order to allow Colaboratory to connect to your locally running Jupyter server, you'll need to perform the following steps.
> Step 1: Install Jupyter
> Install Jupyter on your local machine.
> Step 2: Install and enable the jupyter_http_over_ws jupyter extension (one-time)
> The jupyter_http_over_ws extension is authored by the Colaboratory team and available on GitHub.
pip install jupyter_http_over_ws
jupyter serverextension enable --py jupyter_http_over_ws
> Step 3: Start server and authenticate
> New notebook servers are started normally, though you will need to set a flag to explicitly trust WebSocket connections from the Colaboratory frontend.
jupyter notebook
--NotebookApp.allow_origin='https://colab.research.google.com'
--port=8888
--NotebookApp.port_retries=0
> Once the server has started, it will print a message with the initial backend URL used for authentication. Make a copy of this URL as you'll need to provide this in the next step.
