  # Experimental CPython branch without the Global Interpreter Lock:
  # https://github.com/colesbury/nogil/
  #
  # The nogil build relies on a dedicated PyPI-style index to install patched
  # versions of NumPy, SciPy and Cython maintained by @colesbury and that
  # include specifc fixes to make them run correctly without relying on the GIL.
  #
  # The goal of this CI entry is to make sure that we do not introduce any
  # dependency on the GIL in scikit-learn itself. An auxiliary goal is to early
  # detect any regression in the patched build dependencies to report them
  # upstream. The long-term goal is to be able to stop having to maintain
  # multiprocessing based workaround / hacks in joblib / loky to make multi-CPU
  # computing in scikit-learn efficient by default using regular threads.
  #
  # If this experimental entry becomes too unstable, feel free to disable it.
