Okay, even better news. After a little bit of probing around, it
turns out that some of the errors, namely the one in the interpolator,
were due to intel's handling of floating point values at higher
optimization levels. Thus the two rather important flags, if you wish
to avoid difficult-to-expla

Backtrace would be useful here. It's probably best to recompile with
"-O0" and some debug flags enabled in the compiler to get something
reasonable out.
Okay, last update. I finally have got everything to work.
It turns out the problems that I had earlier with f2py were due to
intel's -ipo flag. So the only place this flag works is with the C++
code, not fortran or c.
Also, I forgot to mention -- the qhull_a.h method has a workaround for

I'm working on getting support for 16-bit floats into cython and have
run into what seems like a numpy bug (I'm a new contributor to both
projects, so bear with me ;).

Hi,
Here are some updated compile flags for HP-UX that were submitted on

By the way, what is the resonable array index for AMD64, where 32-bit is
the native offset size but size_t is 64 bit?

FFTs should keep the GIL locked, because sharing the interpreter is not
funny.
Array indices should be sizeof(void*), because following C standard and
Python C API is lame.
Median should be calculated in O(n log n) instead of O(n) time, because
redundant sorting is gymnatics for the CPU.

Dear sir,
I have a numpy array,,. in which i have to choose only different values
only,
For example
Let A= [ 20. 21. 22. 23. 24. 25. 20. 21. 22. 23. 24. 25.
20. 21. 22. 23. 24. 25. 20. 21. 22. 23. 24. 25. 20. 21. 22.
23. 24. 25.]
then
the answer is [20, 21. 22. 2

We do not decide what Ubuntu and/or debian are putting into their
release. You should send bug report to those distributions bug
trackers if you want to see things improve for those distributions.

Okay, so here's a follow up on my progress. Apologies in advance for
the long email here, but I'd like to be thorough about this before I
forget.
For the sake of completeness, here's my setup. I'm running python
