** Dry-run phase: A set of dry-run (validation) data for each sub-track is provided for debugging purpose only. This set is provided just to validate your prediction format (so you can work with our final testing in the end). The Top-1 Accuracy on this set is not accurate due to small amount of data. Feedback are provided on this dry-run (validation) set only.

Winner Validation and Confirmation Process

Teams with Top-7 on the final testing Codalab leaderboard would be required to submit their code for the winner validation and confirmation process. Please follow the instructions below carefully to ensure smooth confirmation process of your results:

  1. Download the training/validation/testing datasets. The testing dataset would be available for download on April 30 (GMT+0, 00:00).
  2. Train or finetune your model. For obtaining the final testing result, run your trained model on the testing set.
  3. Pack your code into one single .zip file. By default we would be using raw video as the input to your code. If your algorithm requires the use of individual video frame, include you frame extraction code as well in the zip file.
  4. Include a detailed instruction of the placement of the training, validation and testing data (i.e. where to place the data to enable training and testing).
  5. You should contain at most three running scripts, one for data pre-processing (named run_preproc.sh), one for training (named run_train.sh) and one for testing (inference) (named run_test.sh). We will ONLY run the three scripts during the validation process.
  6. Including the trained weight of your algorithm that could lead to the result shown in the leaderboard is highly recommended.
  7. Each team must only submit ONLY ONE zip file with ONLY ONE SET of algorithm corresponding to the submission result in the testing leaderboard. The zip file should contain all dependencies and code required to perform the algorithm's operation.

Running with NVIDIA Container Toolkit (nvidia-docker)

To ensure a smooth validation and confirmation process, we strongly recommend participants to run or verify their code with Docker and NVIDIA Container Toolkit (nvidia-docker). Here we provide detailed instructions to install and run nvidia-docker.

  1. Install NVIDIA GPU Driver using .run file. To ensure that you could run the required docker image, please install the GPU Driver with version >= 440.33.
  2. For the convenience of all participants, you may run the script provided here. Alternatively, follow the following steps.
  3. Install docker and nvidia-docker following the instructions provided by NVIDIA here. You may also choose to install older docker version following the instructions provided by Docker here.
  4. Our default docker image is pulled from NVIDIA NGC Catelog, the details of the docker is provided below. Follow the following two steps to pull and run the default docker image (also provided here or here):
    Using Pytorch:
    • docker pull nvcr.io/nvidia/pytorch:20.02-py3
    • docker run --gpus all -it --rm -v {local_dir}:{container_dir} nvcr.io/nvidia/pytorch:20.02-py3 (Docker >= 19.03)
    • nvidia-docker run -it --rm -v {local_dir}:{container_dir} nvcr.io/nvidia/pytorch:20.02-py3 (Docker <= 19.02)
    Using TensorFlow2:
    • docker pull nvcr.io/nvidia/tensorflow:20.03-tf2-py3
    • docker run --gpus all -it --rm -v {local_dir}:{container_dir} nvcr.io/nvidia/tensorflow:20.03-tf2-py3 (Docker >= 19.03)
    • nvidia-docker run -it --rm -v {local_dir}:{container_dir} nvcr.io/nvidia/tensorflow:20.03-tf2-py3 (Docker <= 19.02)
    Using TensorFlow1:
    • docker pull nvcr.io/nvidia/tensorflow:20.03-tf1-py3
    • docker run --gpus all -it --rm -v {local_dir}:{container_dir} nvcr.io/nvidia/tensorflow:20.03-tf1-py3 (Docker >= 19.03)
    • nvidia-docker run -it --rm -v {local_dir}:{container_dir} nvcr.io/nvidia/tensorflow:20.03-tf1-py3 (Docker <= 19.02)
  5. Verify your algorithm using the running docker container. For more information on running docker containers, you may refer to the documentation here.

The use of Docker and nvidia-docker is NOT mandatory, but we would use the above docker images during the validation and confirmation process to ensure fair comparison between algorithms.

Rules

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.
  • 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-track of this 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.

Eligibility

  • 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.
