How to know the current v_num ?

[Hannibal046]

Hi, how can i get the current v_num in LightningModule? self.trainer.v_num? I could not find it in the doc.

This works. Is there any recommended way?
self.trainer.progress_bar_callback.get_metrics(self.trainer,self)['v_num']

self.logger.version also works.
