use the following line in requirements.txt
--index-url https://gitlab-ci-token:<MY_TOKEN>@gitlab.com/api/v4/projects/<PROJECT_ID>/packages/pypi/simple
- <MY_TOKEN> should be the token that you generate on gitlab | preferences | access tokens , you only need the api scope to be activated for that token
- <PROJECT_ID> should be the id (numeric) of the project and can be found on the home page of the repo directly under the project name
once you setup this line you can now add packages that are part of that repo
