all_reduce of ROC_AUC metric

See original GitHub issue

❓ Questions/Help/Support

Hi @vfdev-5 ,

I found that Accuracy and several other metrics can support all_reduce for distributed training, but seems ROC_AUC doesn’t have similar logic? https://github.com/pytorch/ignite/blob/v0.3.0/ignite/contrib/metrics/roc_auc.py as the comments said: https://github.com/pytorch/ignite/blob/v0.3.0/ignite/metrics/epoch_metric.py#L20 How to accumulate all the predictions and labels from all processes and compute AUC?

Thanks.
