   Thanks @xinyu-intel for the testing!
   
   @apeforest I think @szha answered your question on the dev list: https://lists.apache.org/thread.html/5264c271ea1f87bf747c8fa44cece82df966fc950ab920c5f109f0de@%3Cdev.mxnet.apache.org%3E . We should discuss deprecating warpctc specifically on the dev list. 
   
   It seems that warpctc does more than just ctc loss, it seems like it also does grouping/sorting. There is an example of removing warp ctc and just grouping the features manually: https://github.com/Xilinx/mxnet/blob/master/example/warpctc/lstm.py#L114. So basically group manually, rather than use warpCTC "loss" to do it. So might not be a 1-to-1 replacement with the ctc_loss operator.
