D2Go model demo built with PlayTorch and Torchvision ops

D2Go Example

The repository contains code for a PlayTorch object detection prototype. The prototype uses a quantized D2Go model for the object detection task and runs on-device. It runs on Android and iOS.

NOTE: This example uses an unreleased version of PlayTorch including a complete PyTorch Mobile Module API.

How was this project bootstrapped?

The project was bootstrapped with the following command:

npx torchlive-cli init D2GoExample
