Combination of fast_rnnt and fast_emit about fast_rnnt

[pkufool]

Sorry for the late reply, we have a discussion in k2 repository (k2-fsa/k2#955) and we are doing experiments, finally we will add something to make symbols emit earier.

@Butterfly-c The delay_penalty in k2-fsa/k2#955 has been merged, you can try it. It behaves as good as fast_emit. If you really want the fast_emit, you can try k2-fsa/k2#1069 (by installing k2 or modifying fast_rnnt according to this PR).

-- Could NOT find CUDNN (missing: CUDNN_LIBRARY_PATH CUDNN_INCLUDE_PATH)

From the error log, you have not installed cuDNN yet.

Also, your installed CUDA is 9.2, which is quite old. I am not sure whether it works.
I suggest that you upgrade your CUDA and PyTorch.

-- No NVCC detected. Disable CUDA support

From the above logs, I suggest installing a CUDA version of PyTorch. Otherwise, it would be slow in training with CPU.

From the output of cmake

-- C++ Standard version: 14
-- No NVCC detected. Disable CUDA support

How did you compile fast_rnnt? Do you have the compilation logs?

The error logs show that you have compiled a CPU version of fast_rnnt.
