Repository for the AutoML Decathlon submission - Team Freiburg-AutoML-Lab

======================================

The 10 developoment datasets were hosted on Google cloud storage. First, you need to install the gcloud CLI. Then run the following command line to download the datasets, is:

gsutil cp -r gs://decathlon_public_datasets/dev_public <path_public_data>

Note that this can take some time, depending on your connection.

To make your own submission, you need to modify the file model.py in Decathlon_sample_code_submission/, which implements the logic of your algorithm. You can then test it on your local computer using Docker, in the exact same environment as on the CodaLab challenge platform.

If you are new to docker, install docker from https://docs.docker.com/get-started/. Also make sure you have installed nvidia-docker. Then at the shell, run:

cd path/to/decathlon_starter_kit
docker pull automldec/decathlon
docker run --gpus all --rm -it -v "$(pwd):/app/codalab" -v "<path_public_data>:/app/codalab/dev_public" -w "/app/codalab" -p 8888:8888 automldec/decathlon:latest

The option -p 8888:8888 is useful for running a Jupyter notebook tutorial inside Docker. If the port 8888 is occupied, you can use other ports, e.g. 8899, and use instead the option -p 8899:8888. Note that <path_public_data> should be your absolute path to dev_public.

You will then be able to run the ingestion program (to produce predictions) and the scoring program (to evaluate your predictions) on public data

We provide a tutorial in the form of a Jupyter notebook. When you are in your docker container, enter:

jupyter-notebook --ip=0.0.0.0 --allow-root &

Then copy and paste the URL containing your token. It should look like something like that:

http://0.0.0.0:8888/?token=76a9ef49ecb17899f3fe290f20c5902a90973aab15be91dc

and select the Jupyter notebook in the menu.

We provide a Python script to simulate this CodaLab workflow:

python run_local_test.py --code_dir=./sample_code_submission --dataset_dir=./dev_public --time_budget=60

You can refer to the source code at

• Ingestion Program: ingestion/ingestion.py
• Scoring Program: scoring/score.py

The ingestion program can be run using the following command:

python ingestion/ingestion.py --dataset_dir=./dev_public --code_dir=./sample_code_submission --time_budget=60.0

and the scoring program can be run as follows:

python scoring/score.py --dataset_dir=./dev_public

Make sure you include at least model.py and a metadata file in the submission folder. You can add an optional tasks_to_run.yaml to include the tasks for the submission to run. Then zip the contents of sample_code_submission,

cd sample_code_submission/
zip -r mysubmission.zip *

then use the "Upload a Submission" button to make a submission to the competition page on CodaLab platform.

Tip: to look at what's in your submission zip file without unzipping it, you can do

unzip -l mysubmission.zip

Some of the codes in ingestion/scoring programs and model.py were adapted from past AutoDL competitions.
