Detectron_k8s
Detectron is the object detection collection from Facebook Research. Original repo is here. Since facebook research version could encounter some errors during parsing yaml file, I have fixed this issue by fixing pyyamml version in requirement.txt. Related Issue In my repository I use my forked version of Detectron and works well now.
Clone this repository with submodule: git clone --recursive git@github.com:TeeboneTing/Detectron_k8s.git
Build image: make build
If you would like to push to your dockerhub repository, please change your username in Makefile line 3 and make push_dockerhub
Run image by docker run -ti teeboneding/detectron bash
Execute example inference command inside container from GETTING_STARTED:
python tools/infer_simple.py --cfg configs/12_2017_baselines/e2e_mask_rcnn_R-101-FPN_2x.yaml --output-dir /tmp/detectron-visualizations --image-ext jpg --wts https://dl.fbaipublicfiles.com/detectron/35861858/12_2017_baselines/e2e_mask_rcnn_R-101-FPN_2x.yaml.02_32_51.SgT4y1cO/output/train/coco_2014_train:coco_2014_valminusminival/generalized_rcnn/model_final.pkl demo
According to dataset readme, create your own dataset with COCO format and put into path detectron/datasets/data
.
To add your dataset into Detectron catalog, please refer to dataset_catalog.py. Add your dataset information in _DATASETS
dict.
Make a soft link for dataset to
correct place
Setup RetinaNet config files and model output path
Inside the container with commands below:
ln -s /tmp/detectron/coco /detectron/detectron/datasets/data/coco ; python tools/train_net.py --cfg new_configs/getting_started/retinanet_X-101-32x8d-FPN_1x.yaml OUTPUT_DIR /tmp/detectron/detectron/model
