## InternImage-based Baseline for CVPR23 OpenLane-V2 Challenge!!!!

We improve our baseline with a more powerful image backbone: **InaternImage**, which shows its excellent ability within a series of leaderboards and benchmarks, such as *COCO* and *nuScenes*.


#### 1. Requirements
```bash
python>=3.8
torch==1.11
mmcv-full>=1.5.2
mmdet==2.28.0
mmsegmentation==0.29.1
timm
```


### 2. Install DCNv3 for InternImage
```bash
cd plugin/mmdet3d/baseline/models/backbones/ops_dcnv3
bash make.sh # requires torch>=1.10
```

### 3. Train with InternImage-Small

```bash
./tools/dist_train.sh plugin/mmdet3d/configs/internimage-s.py 8
```

Notes: InternImage provides abundant pre-trained model weights that can be used!!!
