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: http://stackoverflow.com/questions/23963997/python-child-process-crashes-on-... I have Numpy 1.9.1 on Ubuntu 12.04. How can I fix this? Is this a known problem? Kind Regards, Albert
