Description

For my research I need to be able to perform dimensionality reduction in parallel and then plot
the results for analysis. In order to perform experiments more efficiently is use joblib for local
parallel computing. However, every time i try to perform SVD in a spawned process, that process
unexpectedly crashes inside a call to some routine in BLAS. The strangest thing is that the crashes
happen only when I specifically import matplotlib.pyplot.

I managed to produce a what seems to be the bare minimum script required to reproduce
the fault. I also prepared an archive with the crash report and a frozen list of pip packages.

I did some searching and found an issue similar to this one in scikit-image.
