### Installation
The setup of the decoder for deployment depends on the source code of [kenlm](https://github.com/kpu/kenlm/) and [openfst](http://www.openfst.org/twiki/bin/view/FST/WebHome), first clone kenlm and download openfst to current directory (i.e., `deep_speech_2/deploy`)

```shell
git clone https://github.com/kpu/kenlm.git
wget http://www.openfst.org/twiki/pub/FST/FstDownload/openfst-1.6.3.tar.gz
tar -xzvf openfst-1.6.3.tar.gz
