Allow both every and once args to be defined in Events.* #1541
Description
🚀 Feature
Allow users to define both every and once arguments in Events.*
The use case is I want to log the training loss at the first iteration to check that the loss makes sense or not, and then log the training loss at every iteration.
As of today per Events docs, we can use like
e = Events.ITERATION_COMPLETED(every=100) | Events.ITERATION_COMPLETED(once=1)
@engine.on(e)
def log_loss(engine):
...It would be more useful if we can use like
e = Events.ITERATION_COMPLETED(every=100, once=1)
@engine.on(e)
def log_loss(engine):
