The repository contains code for a PyTorch Live question answering prototype. The prototype uses the Distilbert model for the question answering task and runs on-device. It runs on Android and iOS.

NOTE: This example uses an unreleased version of PyTorch Live including an API that is currently under development and can change for the final release.

The project was bootstrapped with the following command:

npx torchlive-cli@nightly init NLPExample --template react-native-template-pytorch-live@nightly

Unused packages were removed and react-native upgraded to version 0.64.3.
