# D2Go Model Zoo and Baselines

## Introduction

This page holds a reference for example configs, pretrained models and training/evaluation metrics. You can access these models from code using d2go.model_zoo API.

### How to

- Get pretrained models in python:

  ```python
  from d2go.model_zoo import model_zoo
  model = model_zoo.get('faster_rcnn_fbnetv3a_C4.yaml', trained=True)
  ```

- Train: the "name" column contains a link to the config file. Running `d2go.train_net --config-file` with the config file will reproduce the corresponding model.

- Evaluation: Running  `d2go.train_net --config-file path/to/the/config --eval-only MODEL.WEIGHTS path/to/the/model/weights` with the config file and pretrained model will evaluate the results. See details in [Getting Started](./demo/README.md).

- Training curves and other statistics can be found in `metrics` for each model.

### Backbone Models

FBNet series are efficient mobile backbones discovered via neural architecture search, which are specially optimized for mobile devices. Please see details in the [paper](https://arxiv.org/pdf/2006.02049.pdf). If using our code/models in your research, please cite our paper:
