RuntimeError: Freigabe entsperrt Sperre beim Training doc2vec

Question

Ich bekomme den folgenden Fehler beim Training eines Doc2vec-Modells in einem Jupyter Notebook auf OS X. Der Fehler ist reproduzierbar (obwohl der spezifische Thread, in dem es auftritt) für meine aktuelle Datenmenge , obwohl ich erfolgreich Modelle in anderen Datensätzen trainiert habe.

Höchstwahrscheinlich ein Numpy-Problem. Siehe Diskussion in gensim bug tracker.
