My (second-hand) understanding is that this is a problem with having multiple CPython interpreters, which both Jepp and numpy utilize, incompatibly - is that right? I.e., if either one were restricted to using a single CPython interpreter, we wouldn't see this problem? I'm curious how to disable threads in numpy (not an ideal solution). Googling seems to point me to setting NPY_ALLOW_THREADS to 0....somewhere. > > Cheers > > Robin > > [1] https://github.com/kw/pymex > >> >> http://stackoverflow.com/questions/7592565/when-embedding-cpython-in-java-why-does-this-hang/7630992#7630992 >> http://mail.scipy.org/pipermail/numpy-discussion/2009-July/044046.html >> Is there any fix or workaround for this?
