      Fix Adam and AdamW initializers in wav2letter example (#3145) · cea12eaf
      Maciej Torhan authored 
      Summary:
In wav2letter example there is passed `momentum` to `Adam` and `AdamW` initializer, which is not a correct parameter. To fix that we need to add `beta_1` and `beta_2` to arguments and replace `momentum` with them. I also added `eps` similar to `Adadelta` initializer.

      Replace c10::Dict with std::map in StreamReader/Writer (#3092) · c3310018
      moto authored 
      Summary:
This commit is kind of clean up and preparation for future development.

We plan to pass around more complicated objects among StreamReader and StreamWriter, and TorchBind is not expressive enough for defining intermediate object, so we want to use PyBind11 for binding StreamReader/Writer.

PyBind11 converts Python dict into std::map, while TorchBind converts it into c10::Dict. Because of this descrepancy, conversion from c10::Dict to std::map have to happen in multiple places, and this makes the binding code thicker as it requires to wrapper methods.

Using std::map reduces the number of wrapper methods / conversions, because the same method can be bound for file-like object and the others.

      Add TCPGen context-biasing Conformer RNN-T (#2890) · 1ed330b5
      G. Sun authored 
      Summary:
This commit adds the implementation of the tree-constrained pointer generator (TCPGen) for contextual biasing.

An example for Librispeech can be found in audio/examples/asr/librispeech_biasing.

Maintainer's note (mthrok):
It seems that TrieNode should be better typed as tuple, but changing the implementation from list to tuple
could cause some issue without running the code, so the code is not changed, though the annotation uses tuple.
