sbodenstein commented on issue #5559: CTC Loss Refactor URL: https://github.com/apache/incubator-mxnet/issues/5559#issuecomment-327913083 > As I see contrib CTC is implemented inside mxnet without dependence of baidu's warpctc. @buaacszj: the contrib CTC implementation is basically just Warp-CTC (with one or two smallish changes). The Warp-CTC implementation was copied and adapted so that it could be compiled together with MXNet (rather than annoyingly having to compile it separately). If it has any speed difference, that will surprising (could you give the exact configuration you saw these large differences in speed for? And was this GPU or CPU?) Also: @szha did some speed tests against cuDNN (https://github.com/apache/incubator-mxnet/pull/7442). I think that this tested against the contrib symbol CTC, which was quite competitive with cuDNN CTC. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
