[Numpy-discussion] Hang in numpy.zeros

[Albert Zeyer]

Hi,

I have a multithreaded multiprocessing Python 2.7 project with Theano.

In my main proc, I recognized a hang in numpy.zeros. It deadlocks with
the Python GIL and other native threads will lock on the Python GIL.

I found a somewhat related problem described here about such a
deadlock in numpy.dot:

I have Numpy 1.9.1 on Ubuntu 12.04.

How can I fix this? Is this a known problem?

Kind Regards,
Albert
