## Quick Start
#### Train a detection model
```bash
cd SeetaDet/tools
python train.py --cfg <MODEL_YAML>
```
We have provided the default YAML examples into ``SeetaDet/configs``.
#### Test a detection model
```bash
cd SeetaDet/tools
python test.py --cfg <MODEL_YAML> --exp_dir <EXP_DIR> --iter <ITERATION>
```
Or
```bash
cd SeetaDet/tools
python test_all.py --cfg <MODEL_YAML> --exp_dir <EXP_DIR>
```
#### Export a detection model to ONNX
```bash
cd SeetaDet/tools
python export.py --cfg <MODEL_YAML> --exp_dir <EXP_DIR> --iter <ITERATION>
