Doing "import sklearn" resulted in breakage at runtime due to sklearn
0.20.3 not being compatible with python 3.8.
In addition:
- add WANTLIB
- rework the DEPs for the new version
- remove SKLEARN_NO_OPENMP which was dropped in commit 9876f748
Breakage initially reported by James Cook (who provided many pointers on
moving forward) and also tested the update.
scikit-learn is a BSD-licensed Python module for machine learning
and data mining built on top of SciPy.
Initially created by robert@, modified by me and kmos@.
This is not polished enough, but it can improved in the tree now.
Once the 21 branch rolls out a new version, we will probably update to that.
Currently it is broken for non-OpenMP builds.
OK robert@, kmos@
