That feature relies on the imported module's `__version__` attribute, but all our major dependencies support it, so we should be fine.","author":{"url":"https://github.com/plamut","@type":"Person","name":"plamut"},"datePublished":"2021-07-12T12:39:58.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/752/python-bigquery/issues/752"}
