在Pytorch-lightning 中,on_validation_epoch_end和validation_epoch_end这两个方法在验证过程中起着不同的作用。 on_validation_epoch_end在每个验证轮次结束时被调用,用于执行验证结束时需要进行的操作,如记录指标、保存模型等。 validation_epoch_end在所有验证轮次结...

🐛 Bug I'm not sure if this is expected behaviour or not, but upgrading to the latest version (from 0.8.1) caused my validation_epoch_end to break. It appears that a CUDA tensor is expected for the metric where before the tensor was devic...

🐛 Bug The on_epoch_end is called before the epoch ends. What I'm doing: in the pl model I have the validation_epoch_end which computes an accuracy which I log with self.log("val/meta_acc", meta_acc) I have a callback with a single method...
Though I imagine there may not be many situations where this may have an impact (as accessing training metrics using theon_validation_epoch_endhook would be unusual) I find the behaviour somewhat confusing. I suspect this may be due to the order in which the hooks are executed. Is this int...
When ison_validation_epoch_start/on_validation_epoch_endbeing called? It there a doc that explains the order of the callback function being called? I need a callback function that will be called at the end of every validation epoch.
