What is the difference between warp_ctc_pytorch.ctcloss and torch.nn.ctcloss?

[arwagh]

I noticed that this project and several more use warp_ctc_pytorch.ctcloss instead of torch.nn.ctcloss, however, installing warp_ctc_pytorch library did not work with me, so may I know what is the different between these two functions? does using torch.nn.ctcloss may raise some problems form me?

Thank you!

I hope my answer is still necessary. I believe the main difference is in the performance. warp_ctc performs the fastest when compared to the other CTC Loss functions as described in the README
