# Co-tuning for Transfer Learning <br />Supervised Contrastive Learning
|
||||
|
||||
## Data preparation
|
||||
以[Kaggle数据集](https://www.kaggle.com/andrewmvd/road-sign-detection) 比赛数据为例,说明如何准备自定义数据。
|
||||
Kaggle上的 [road-sign-detection](https://www.kaggle.com/andrewmvd/road-sign-detection) 比赛数据包含877张图像,数据类别4类:crosswalk,speedlimit,stop,trafficlight。
|
||||
可从Kaggle上下载,也可以从[下载链接](https://fsdet-dataset.bj.bcebos.com/roadsign_coco.tar.gz) 下载。
|
||||
分别从原始数据集中每类选取相同样本(例如:10shots即每类都有十个训练样本)训练即可。<br />
|
||||
工业数据集使用PKU-Market-PCB,该数据集用于印刷电路板(PCB)的瑕疵检测,提供了6种常见的PCB缺陷[下载链接](https://fsdet-dataset.bj.bcebos.com/pcb.tar.gz)

## Training & Evaluation & Inference
|
||||
### 1、Training
|
||||
|
||||
```
|
||||
# -c 参数表示指定使用哪个配置文件
|
||||
# --eval 参数表示边训练边评估,训练过程中会保存验证效果最佳的checkpoint
|
||||
|
||||
python tools/train.py -c configs/few-shot/faster_rcnn_r50_vd_fpn_1x_coco_cotuning_roadsign.yml --eval
|
||||
```
|
||||
### 2、Evaluation
|
||||
```
|
||||
# -c 参数表示指定使用哪个配置文件
|
||||
# -o 参数表示指定配置文件中的全局变量(覆盖配置文件中的设置)
|
||||
|
||||
python tools/eval.py -c configs/few-shot/faster_rcnn_r50_vd_fpn_1x_coco_cotuning_roadsign.yml \
|
||||
-o weights=output/faster_rcnn_r50_vd_fpn_1x_coco_cotuning_roadsign/best_model
|
||||
```
|
||||
|
||||
|
||||
### 3、Inference
|
||||
```
|
||||
# -c 参数表示指定使用哪个配置文件
|
||||
# --infer_img 参数指定预测图像路径
|
||||
|
||||
python tools/infer.py -c configs/few-shot/faster_rcnn_r50_vd_fpn_1x_coco_cotuning_roadsign.yml \
|
||||
--infer_img=demo/road554.png
|
||||
```
