This is an open solution to the Google AI Open Images - Object Detection Track 😃

We are building entirely open solution to this competition. Specifically:

1. Learning from the process - updates about new ideas, code and experiments is the best way to learn data science. Our activity is especially useful for people who wants to enter the competition, but lack appropriate experience.
2. Encourage more Kagglers to start working on this competition.
3. Deliver open source solution with no strings attached. Code is available on our GitHub repository 💻. This solution should establish solid benchmark, as well as provide good base for your custom ideas and experiments. We care about clean code 😃
4. We are opening our experiments as well: everybody can have live preview on our experiments, parameters, code, etc. Check: Google-AI-Object-Detection-Challenge 📈 and images below:

UNet training monitor 📊	Predicted bounding boxes 📊

In this open source solution you will find references to the neptune.ml. It is free platform for community Users, which we use daily to keep track of our experiments. Please note that using neptune.ml is not necessary to proceed with this solution. You may run it as plain Python script 🐍.

1. Check Kaggle forum and participate in the discussions.
2. Check our Wiki pages 🐬, where we describe our work. Below are link to specific solutions:

This competition is special, because it used Open Images Dataset V4, which is quite large: >1.8M images and >0.5TB 😲 To make it more approachable, we are hosting entire dataset in the neptune's public directory 😎. You can use this dataset in neptune.ml with no additional setup 👍.

You can jump start your participation in the competition by using our starter pack. Installation instruction below will guide you through the setup.

1. Clone repository, install tensorflow 1.6, PyTorch 0.3.1 and then remaining requirements (check requirements.txt)

pip3 install -r requirements.txt

2. Register to the neptune.ml (if you wish to use it)
3. Train RetinaNet:

🔱

neptune run main.py train --pipeline_name retinanet

🐍

python main.py train --pipeline_name retinanet

You are welcome to contribute your code and ideas to this open solution. To get started:

1. Check competition project on GitHub to see what we are working on right now.
2. Express your interest in paticular task by writing comment in this task, or by creating new one with your fresh idea.
3. We will get back to you quickly in order to start working together.
4. Check CONTRIBUTING for some more information.

There are several ways to seek help:

1. Kaggle discussion is our primary way of communication.
2. Read project's Wiki, where we publish descriptions about the code, pipelines and supporting tools such as neptune.ml.
3. Submit an issue directly in this repo.
