WORKDIR /mmdetection

build:

docker build -f Dockerfile -t kevinchina/deeplearning:mmdetection_train .

run docker container:

docker run --gpus all -it -v $PWD:/mmdetection/data kevinchina/deeplearning:mmdetection_train bash

修改mmcv版本：

mim install mmcv==2.0.0rc4

数据

为了便于测试，下载数据集
https://pjreddie.com/projects/pascal-voc-dataset-mirror/#google_vignette

cd data
wget http://pjreddie.com/media/files/VOCtrainval_06-Nov-2007.tar
tar xf VOCtrainval_06-Nov-2007.tar

测试

https://github.com/open-mmlab/mmdetection/tree/main/configs/faster_rcnn

在 Pascal VOC 数据集上测试 Faster R-CNN，不保存测试结果，测试 mAP。

下载一个faster rcnn权重：
https://github.com/open-mmlab/mmdetection/blob/main/configs/faster_rcnn/metafile.yml

mkdir checkpoints
cd checkpoints
wget https://download.openmmlab.com/mmdetection/v2.0/faster_rcnn/faster_rcnn_r50_fpn_1x_coco/faster_rcnn_r50_fpn_1x_coco_20200130-047c8118.pth

执行测试，单卡测试：

python tools/test.py \
    configs/pascal_voc/faster-rcnn_r50_fpn_1x_voc0712.py \
    checkpoints/faster_rcnn_r50_fpn_1x_voc0712_20200624-c9895d40.pth

emmmm，，这mmdetection的配置文件的方式真老火啊，例子不太多，算了，节约时间，直接用别的代码，就此打住。
