I have a same problem.
But I couldn’t understand how did you solve the problem.
Could you please explain in detail?
I have an error saying that “AttributeError: module ‘warpctc_pytorch’ has no attribute ‘cpu_ctc’” when running the python test script which is shown in the installation guide of warp-ctc/pytorch_binding.
I would like to know what you did for the last comment which says that you converted LongTensor to IntTensor, because I couldn’t find any LongTensors.
