![]() Google Compute Engine instance) and specify the '-L' flag. Second, establish an SSH connection from your local machine to the remote instance (e.g. Google Compute Engine instance), you can set up SSH local port forwarding to allow Colab to connect to it.įirst, set up your runtime using the instructions above. If the runtime you'd like to connect to is running on another machine (e.g. ![]() If your local connection will access sensitive data and you would like to omit code cell outputs, select Edit > Notebook settings > Omit code cell output when saving this notebook.Ĭonnecting to a runtime on another machine When others open the shared notebook, they will be connected to a standard Colab hosted 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. Colab 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 Colab, 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 Colab frontend. The URL to use in the next step will be with replaced by the token value provided in the output. Packages (files in general) installed on your local machine are however not available by default. The Docker image includes packages found in our hosted runtime environments ( ) and enables some UI features such as debugging and the resource utilization monitor. You can either run Jupyter directly or use Colab's Docker image. 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 Colab 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 runtime 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. Colab lets you connect to a local runtime.
