Re: [Numpy-discussion] Problem introduced after 1.0rc2 on AIX with xlc
So, I have figured out the problem and have a solution. I have submitted a ticket for this: http://projects.scipy.org/scipy/numpy/ticket/362 That describes the problem and solution. Thanks for everyones ideas on this. Brian On 10/21/06, Travis Oliphant [EMAIL PROTECTED] wrote: Brian Granger wrote: Hi, i am running numpy on aix compiling with xlc.

Brian Granger wrote: Tim, I just tried everything with r3375. I set seterr(all='warn') and the tests passed. But all the floating point warning are still there. With seterr(all='ignore') the warnings go away and all the tests pass. should I worry about the warnings? Maybe. I just sent you some email on this. But my guess is that the code that checks for FP errors is broken on your particular system. Mainly I suspect this because I think you would have noticed by now if everything was as broken as the warnings seem to indicate. Assuming that's the case, and this will probably become clear if you test a bunch of computations that give correct (and non INF/NAN) results, but still spit out warnings, you have two choices: try to fix the warnings code or disable the warnings. The former would be preferable since then you could actually use the warnings code, but it may be a pain in the neck unless you can find some place to steal the relevant code from. -tim thanks Brian On 10/20/06, Tim Hochberg [EMAIL PROTECTED] wrote: Brian Granger wrote: Also, when I use seterr(all='ignore') the the tests fail: == FAIL: Ticket #112 -- Traceback (most recent call last): File /usr/common/homes/g/granger/usr/local/lib/python/numpy/core/tests/test_regression.py, line 219, in check_longfloat_repr assert(str(a)[1:9] == str(a[0])[:8]) AssertionError -- Ran 516 tests in 0.823s FAILED (failures=1) Thanks for helping out on this.

Thanks, I will investigate more on these things and get back to you early in the week. But for now numpy seems to be functioning pretty normally (log(2) gives the correct answer). thanks again. It would be great to figure this stuff out before 1.0, but we might not have time.
