Log Message:
py-joblib: updated to 0.15.0

Release 0.15.0

- Drop support for Python 2 and Python 3.5. All objects in
  ``joblib.my_exceptions`` and ``joblib.format_stack`` are now deprecated and
  will be removed in joblib 0.16. Note that no deprecation warning will be
  raised for these objects Python < 3.7.

- Fix many bugs related to the temporary files and folder generated when
  automatically memory mapping large numpy arrays for efficient inter-process
  communication. In particular, this would cause `PermissionError` exceptions
  to be raised under Windows and large leaked files in `/dev/shm` under Linux
  in case of crash.

- Make the dask backend collect results as soon as they complete
  leading to a performance improvement:

- Fix the number of jobs reported by ``effective_n_jobs`` when ``n_jobs=None``
  called in a parallel backend context.

- Upgraded vendored cloupickle to 1.4.1 and loky to 2.8.0. This allows for
  Parallel calls of dynamically defined functions with type annotations
  in particular.
