When others open the shared notebook, they will be connected to a standard Cloud runtime by default.īy default, all code cell outputs are stored in Google Drive. If you share your notebook with others, the runtime on your local machine will not be shared. By default, Firefox disallows connections from HTTPS domains using standard WebSockets. Colaboratory makes a connection to your local kernel using a WebSocket. Note: If you're using Mozilla Firefox, you'll need to set the preference within the Firefox config editor. After this, you should now be connected to your local runtime.

Enter the URL from the previous step in the dialog that appears and click the 'Connect' button.

In Colaboratory, click the 'Connect' button and select 'Connect to local runtime.'. Make a copy of this URL as you'll need to provide this in the next step. Once the server has started, it will print a message with the initial backend URL used for authentication. New notebook servers are started normally, though you will need to set a flag to explicitly trust WebSocket connections from the Colaboratory frontend.

Jupyter serverextension enable -py jupyter_http_over_ws The jupyter_http_over_ws extension is authored by the Colaboratory team and available on GitHub. Step 2: Install and enable the jupyter_http_over_ws jupyter extension (one-time) In order to allow Colaboratory to connect to your locally running Jupyter server, you'll need to perform the following steps. For more information on the Jupyter notebook server's security model, consult Jupyter's documentation. ' rm -rf /')īefore attempting to connect to a local runtime, make sure you trust the authors of the notebook and ensure you understand what code is being executed. By connecting to a local runtime, you are allowing the Colaboratory frontend to execute code in the notebook using the local resources on your machine. With these benefits come serious potential risks. With a local connection, the code you execute can read, write, and delete files on your computer.Ĭonnecting to a Jupyter notebook server running on your local machine can provide many benefits. Make sure you trust the authors of any notebook before executing it. This allows you to execute code on your local hardware and have access to your local file system. Colaboratory lets you connect to a local runtime using Jupyter.
