# Online HD Map Construction Challenge For Autonomous Driving
 </div>

We train a fast version of vectormapnet_intern .


If you need detaild information about the challenge, please refer to https://github.com/Tsinghua-MARS-Lab/Online-HD-Map-Construction-CVPR2023/tree/master
#### 1. Requirements
```bash
python>=3.8
torch==1.11 # recommend
mmcv-full>=1.5.2
mmdet==2.28.1
mmsegmentation==0.29.1
timm
numpy==1.23.5
mmdet3d==1.0.0rc6 # recommend
```


### 2. Install DCNv3 for InternImage
```bash
cd projects/ops_dcnv3
bash make.sh # requires torch>=1.10
```

### 3. Train with InternImage-Small

```bash
bash tools/dist_train.sh src/configs/vectormapnet_intern.py ${NUM_GPUS}
```

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


### 4. Performance compared to baseline
