[issue21162] code in multiprocessing.pool freeze if inside some code from scikit-learn (and probably liblinear) executed on ubuntu 12.04 64 Bit

[Richard Oudkerk]

Richard Oudkerk added the comment:

I would guess that the problem is simply that LogisticRegression objects are 
not picklable.  Does the problem still occur if you do not use freeze?
