# LVIS dataset

## Introduction

<!-- [DATASET] -->

```

## Common Setting

* Please follow [install guide](../../docs/install.md#install-mmdetection) to install open-mmlab forked cocoapi first.
* Run following scripts to install our forked lvis-api.

    ```shell
    pip install git+https://github.com/lvis-dataset/lvis-api.git
    ```

* All experiments use oversample strategy [here](../../docs/tutorials/new_dataset.md#class-balanced-dataset) with oversample threshold `1e-3`.
* The size of LVIS v0.5 is half of COCO, so schedule `2x` in LVIS is roughly the same iterations as `1x` in COCO.
