Submission Process

Winner/Runner-up Validation Process

We appreciate the strong GPU support from NVIDIA!

Winner and two runner-ups on leaderboard are required to submit their code for the validation. Please follow steps below:

  1. Please send us the docker image (a link to pull) by May 15th EOD.
  2. The docker image needs to include training and evaluation script and data to fully reproduce the original submission. We'll re-train your model using your scripts. If the reproduced results differ too much from the submissions, your team will likely be disqualified.
  3. Please feel free to provide a README file as well as relevant information that might help us reproduce. Please provide instructions on how to run your training scripts as well as your testing scripts inside the docker image (using an interactive shell e.g. bash, zsh).
  4. Please provide requirements.txt or conda environment.yml file if we need to install additional packages.
  5. If you are not familiar with docker, you may build upon existing images e.g.


  • A6000 GPU
  • CUDA Version 11.4
  • NVIDIA Driver 470.103.01
  • Docker version 20.10.8, build 3967b7d

Read carefully the following guidelines before submitting. Methods not complying with the guidelines will be disqualified.

  • We encourage participants to use the provided training and validation data for each task, as well as to make use of their own data or data from other sources for training. However the use any form of annotation or use of any of the provided benchmarks test sets for either supervised or unsupervised training is strictly forbidden. Winner/Runner-up teams must also upload labeled data they used.
  • Team name of submissions on Codalab must match the registration information. Any submission with a team name not registered will not be qualified for prizes. Only a single submission per team can be the winner of a single sub-challenge. Changes in algorithm parameters do not constitute a different method, all parameter tuning must be conducted using the dataset provided and any additional data the participants consider appropriate.


  • Foreign Nationals and International Developers: All Developers can participate with this exception: residents of, Iran, Cuba, North Korea, Crimea Region of Ukraine, Sudan or Syria or other countries prohibited on the U.S. State Department’s State Sponsors of Terrorism list. In addition, Developers are not eligible to participate if they are on the Specially Designated National list promulgated and amended, from time to time, by the United States Department of the Treasury. It is the responsibility of the Developer to ensure that they are allowed to export their technology solution to the United States for the Live Test. Additionally, it is the responsibility of participants to ensure that no US law export control restrictions would prevent them from participating when foreign nationals are involved. If there are US export control concerns, please contact the organizers and we will attempt to make reasonable accommodations if possible.

  • If you are entering as a representative of a company, educational institution or other legal entity, or on behalf of your employer, these rules are binding on you, individually, and/or the entity you represent or are an employee. If you are acting within the scope of your employment, as an employee, contractor, or agent of another party, you warrant that such party has full knowledge of your actions and has consented thereto, including your potential receipt of a prize.

If you provide any false information relating to the prize challenge concerning your identity, email address, ownership of right, or information required for entering the prize challenge, you may be immediately disqualified from the challenge.

  • Accounts. For the final testing phase, you may make submissions only under one, unique registration per team. Submission should be made such that the "Team Name" field in Codalab and the "Team Name" as shown in the "Results" tab matches your team name in the registration. You will be disqualified if you make submissions for your final testing phase through more than one registration or if your team name cannot be found in the registration or if your team name is NOT shown in the "Results" tab. Each TEAM may submit up to ten submissions per day per challenge. For the final winner validation/confirmation process, eligible teams should submit code containing only ONE algorithms per TEAM. Any submissions that does not adhere to this during the testing or winner validation/confirmation process may be subject to disqualification.

The organizers reserve the right to disqualify any participating team for any of the reasons mentioned above and if deemed necessary.
