Hi Jaonary,
All you have to do is to provide a "competition Docker image" which contains the desired packages.
By default, the scoring program runs inside a container of the Docker image "codalab/codalab-legacy:py37". You can fork it and edit it, or provide your own image.
Just put the DockerHub ID of the image in the right field in the "EDIT" menu, or in the bundle's competition.yaml file (competition_docker_image argument).
I hope this helps.
Best regards,
Adrien
