Add Numba CPU+CUDA support for RNNT Loss #1854

titu1994 · 2021-03-06T03:18:40Z

Changelog

Add Numba CUDA + CPU kernels for RNNT Loss ported from https://github.com/HawkAaron/warp-transducer
Add tests for CUDA + CPU kernels + reference numpy implementation.

Todo:

Add documentation for all kernels and wrapped modules
Add Typing information to RNNTLossNumba (Done by resolver)
Rename this module to avoid clash with original warprnnt_pytorch loss
Add WarpRNNT LICENSE header in all files that implement functionality as ported.
Fix imports inside __init__.py
Enable loss switching for RNNT / RNNTBPE models via config (done in next PR)

is it necessary to have this license here?

Yes, here its needed since the 2 functions and the class is ported from that codebase.

But this is the init file which just contains the imports.
