In Pyro, through tutorials, I found that i in irange or iarange means "independent". And poutine means Pyro Coroutine. But what does Pyro mean? I guess it is "Python Random Operator/Operation/Object"? ^^
that's an interesting theory... the name is just playing on the fact that pyro is written in python and built on top of pytorch. pyro/πυρ means fire in greek.
Thank @martinjankowiak! It is good to know about it.
