Virtual environment

We will need to create another virtual environment for deepspeech-gpu

conda create -n ds-gpu python=3.8 conda activate ds-gpu

Install deepspeech-gpu

pip install deepspeech-gpu

Model and audio files

If you've been following along you can use the same model and audio files from the Deepspeech basics article

If not you can install them like so:

curl -LO https://github.com/mozilla/DeepSpeech/releases/download/v0.6.1/deepspeech-0.6.1-models.tar.gz tar xvf deepspeech-0.6.1-models.tar.gz curl -LO https://github.com/mozilla/DeepSpeech/releases/download/v0.6.1/audio-0.6.1.tar.gz tar xvf audio-0.6.1.tar.gz

Installing CUDA and cuDNN

This goes without saying but make sure you have an Nvidia GPU and the proprietary drivers installed

You will need both of these libraries in order to run inference

If you already have CUDA 10 installed then great you can move on

If not I have an easy way to do so using conda

conda install cudatoolkit=10.0.130 conda install cudnn

Run inference

We can now transcribe the audio file

deepspeech --model deepspeech-0.6.1-models/output_graph.pbmm --audio audio/2830-3980-0043.wav
