Kaggle Airbus Ship Detection Challenge : 21st solution

This project is for Kaggle competiton Airbus Ship Detection Challenge.

It can help you quickly get a baseline solution, which is not bad.

Steps

1. Generate COCO standard dataset

Run codes in ./0_rle_to_coco. The guide has been written in markdwon file ./0_rle_to_coco/README.md

2. Get Detectron environment

My codes are based on Detectron. So before using it, you need to install caffe2, which is quite troublesome. You can use my docker image, which is a little out of date, by the following command:

$ docker pull pascal1129/detectron:caffe2_cuda9_aliyun

In order to get the latest docker image, you can build the latest image with the official dockerfile: Detectron/docker/Dockerfile.

3. Msodify the source code in detectron

My codes are in the folder ./1_detectron_infer/, you can replace the origin files in detectron with my codes.

4. Change the configuration file and run

Confirm the .yaml file in ./2_model/model/ and start training. In addition, remember to use |tee command, so you can get the log file like ./2_model/log/20181103.log

5. Visualization

Run ./2_model/analyse_log.py, then you can get the visualization picture.

6. Get the final submission

Run ./3_submit/get_final_csv.py.
