  # cibuildwheels already manages multiple python versions automatically

  # and therefore in a serial manner. We build a matrix of operating systems
  # and python versions so that builds are ran in parallel.
  # The job matrix is basically copied from https://github.com/scikit-learn/scikit-learn/blob/main/.github/workflows/wheels.yml
