Can you expand a bit? Are you trying to disable threads at
compile-time or at run-time? Which threaded functionality are you
trying to disable? Are you using numpy as a computational library
with multiple threads making calls into its functions? I think
NPY_ALLOW_THREADS is for interacting with

It's appearing to me I had to face this very issue,
which I reported @Numpy TRAC : http://p
Hi Peter,
The obsolete link was not deliberate. It was the first reference I
found via google.

Hi Armando,
No comment on the Java thing ;-)
However,
http://www.opengda.org/documentation/manuals/Diamond_SciSoft_Python_Guide/8.18/contents.html
is more up-to-date and we are on github too:

I recently got interested in multiprocessing computation with numpy and
now I get scare by your statement !
Please don't tell me it

Just wanted to make the point for reference that in general Numpy does
work fine in (non-threaded) embedded CPython s
As far as a workaround in concerned, that scipy archive post says you can
disable threads in numpy.
Sorry can't help more, I don't know much about how to bypass such GIL
issues.

It turns out that there's a long-standing problem in numpy that
prevents it from being used in embedded CPython environments:
