Hi
I’m confused with CTC losses available right now. I think the most popular binding (right now) is sean naren warp-ctc binding 8. But as Sean recommends here 20, we should migrate to use this binding 30 instead. Meanwhile native pytorch CTC loss introduced in Pytorch1.0 is another suggestive option.
Is there any fair comparison between these bindings and native Pytorch1.0 CTC? Which one is faster? And what are most notable differences between warp-ctc and Pytorch1.0 CTC implementation? What are pros and cons of using pytorch CTC instead of warp-ctc?
