***** Beginning of the instructions ****

The image did not pass 'pip check' verification. This means that there are some conflicting dependencies
in the image.

It can mean one of those:

1) The main is currently broken (other PRs will fail with the same error)
2) You changed some dependencies in pyproject.toml (either manually or automatically by pre-commit)
   and they are conflicting.


In case 1) - apologies for the trouble.Please let committers know and they will fix it. You might
be asked to rebase to the latest main after the problem is fixed.

In case 2) - Follow the steps below:

* try to build CI and then PROD image locally with breeze, adding --upgrade-to-newer-dependencies flag
  (repeat it for all python versions)

CI image:

     breeze ci-image build --upgrade-to-newer-dependencies --python 3.8

Production image:

     breeze ci-image build --production-image --upgrade-to-newer-dependencies --python 3.8

* You will see error messages there telling which requirements are conflicting and which packages caused the
  conflict. Add the limitation that caused the conflict to EAGER_UPGRADE_ADDITIONAL_REQUIREMENTS
  variable in Dockerfile.ci. Note that the limitations might be different for Dockerfile.ci and Dockerfile
  because not all packages are installed by default in the PROD Dockerfile. So you might find that you
  only need to add the limitation to the Dockerfile.ci

***** End of the instructions ****
