Bug#918570: python3-sklearn-lib: dependency on libblas3 | libblas.so.3 instead of libatlas3-base?

[Jörg-Volker Peetz]

Hi Christian,

meanwhile the dependency on libatlas3-base is gone and I think the bug can be
closed.
Your second quotation was from an e-mail of Stuart Prescott. Maybe ask him about
his remarks also.

Thank you for caring.
Regrds,
Jörg.
