Torch VGGish

A PyTorch port of VGGish¹, a feature embedding frontend for audio classification models. The weights are ported directly from the tensorflow model, so embeddings created using torchvggish will be identical.

Quick start

There are two options: you can install the last stable version from pypi, or clone this repo and install.

# optional: create virtual env
cd torchvggish && python3 -m venv .env
source activate .env/bin/activate

pip install -i https://test.pypi.org/simple/ torchvggish==0.1

# OR get the latest version
git clone git@github.com:harritaylor/torchvggish.git
pip install -r requirements.txt

Usage

Barebones example of creating embeddings from an example wav file:

from torchvggish import vggish, vggish_input

# Initialise model and download weights
embedding_model = vggish()
embedding_model.eval()

example = vggish_input.wavfile_to_examples("example.wav")
embeddings = embedding_model.forward(example)
