numpy.ma.sort failing with bus error
Hello,
Using numpy 1.2.1 on a mac os 10.5
I admit the user was sort of stretching the limits but (on his machine)
import numpy a=numpy.ones((16800,60,96),'f') numpy.sort(a,axis=0)
works
import numpy.ma a=numpy.ma.sort((16800,60,96),'f') numpy.ma.sort(a,axis=0)
failed with some malloc error: python(435) malloc: *** mmap(size=2097152) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug Bus error
Since there's no mask I don't really see how much more memory it's using. Beside changing 16800 to 15800 still fails (and now that should be using much less memory)
Anyhow I would expect i nicer error than a bus error :)
Thx,
C>
i mistyped the second line of the sample failing script it should obviously read: a=numpy.ma.ones((16800,60,96),'f') not numpy.ma.sort((16800,60,96),'f')

Charles, Confirmed on my machine... I gonna have to clean ma.sort, as there are indeed some temporaries that probably don't need to be created. I must warn you however that I won;t have a lot of time to spend on that in the next few days. In any case, of course, I'll keep you posted. Thx for reporting!

Thx Pierre,
don't worry about it it's not a show stopper at all
