Installation

The build of the decoder for deployment depends on several open-sourced projects, first clone or download them to current directory (i.e., deep_speech_2/deploy)

KenLM: Faster and Smaller Language Model Queries

git clone https://github.com/kpu/kenlm.git

OpenFst: A library for finite-state transducers

wget http://www.openfst.org/twiki/pub/FST/FstDownload/openfst-1.6.3.tar.gz
tar -xzvf openfst-1.6.3.tar.gz

SWIG: Compiling for python interface requires swig, please make sure swig being installed.
ThreadPool: A library for C++ thread pool

git clone https://github.com/progschj/ThreadPool.git

Then run the setup

python setup.py install --num_processes 4
cd ..

Deployment

For GPU deployment

CUDA_VISIBLE_DEVICES=0 python deploy.py

For CPU deployment

python deploy.py --use_gpu=False
