ultralytics.hub.utils.Events

Eine Klasse zum Sammeln anonymer Ereignisanalysen. Die Ereignisanalyse ist aktiviert, wenn sync=True in den Einstellungen und deaktiviert, wenn sync=False. FĂŒhre 'yolo settings' aus, um die YAML-Datei mit den Einstellungen zu sehen und zu aktualisieren.

Attribute:

Name Typ Beschreibung
url str

Die URL zum Senden anonymer Ereignisse.

rate_limit float

Das Ratenlimit in Sekunden fĂŒr das Senden von Ereignissen.

metadata dict

Ein Wörterbuch mit Metadaten ĂŒber die Umgebung.

enabled bool

Ein Flag, um Ereignisse unter bestimmten Bedingungen zu aktivieren oder zu deaktivieren.
