Initialization

def rerun.init(application_id, spawn=False, default_enabled=True, strict=False)

Initialize the Rerun SDK with a user-chosen application id (name).

Parameters:

Name	Type	Description	Default
application_id	str	Your Rerun recordings will be categorized by this application id, so try to pick a unique one for each application that uses the Rerun SDK. For example, if you have one application doing object detection and another doing camera calibration, you could have rerun.init("object_detector") and rerun.init("calibrator").	required
spawn	bool	Spawn a Rerun Viewer and stream logging data to it. Short for calling spawn separately. If you don't call this, log events will be buffered indefinitely until you call either connect, show, or save	False
default_enabled	bool	Should Rerun logging be on by default? Can overridden with the RERUN env-var, e.g. RERUN=on or RERUN=off.	True
strict	bool	If True, an exceptions is raised on use error (wrong parameter types etc). If False, errors are logged as warnings instead.	False

def rerun.connect(addr=None)

Connect to a remote Rerun Viewer on the given ip:port.

Requires that you first start a Rerun Viewer, e.g. with 'python -m rerun'

This function returns immediately.

Parameters:

Name	Type	Description	Default
addr	Optional[str]	The ip:port to connect to	None

def rerun.disconnect()

Closes all TCP connections, servers, and files.

Closes all TCP connections, servers, and files that have been opened with [rerun.connect], [rerun.serve], [rerun.save] or [rerun.spawn].

def rerun.spawn(port=9876, connect=True)

Spawn a Rerun Viewer, listening on the given port.

This is often the easiest and best way to use Rerun. Just call this once at the start of your program.

You can also call rerun.init with a spawn=True argument.

Parameters:

Name	Type	Description	Default
port	int	The port to listen on.	9876
connect	bool	also connect to the viewer and stream logging data to it.	True

def rerun.serve(open_browser=True)

Serve log-data over WebSockets and serve a Rerun web viewer over HTTP.

You can connect to this server using python -m rerun.

WARNING: This is an experimental feature.

This function returns immediately.

Parameters:

Name	Type	Description	Default
open_browser	bool	Open the default browser to the viewer.	True
