Она никогда здесь не падала. Могу хоть 10000x10000 задать
In [1]: from numpy.linalg import *
In [2]: from numpy.random import *
In [3]: from numpy import dot
In [4]: m1=randn(5000,5000)
In [5]: %time m2=randn(5000,5000)
CPU times: user 1.90 s, sys: 0.33 s, total: 2.23 s
Wall time: 6.11 s
In [7]: %time m3=dot(m1,m2)
CPU times: user 104.00 s, sys: 0.67 s, total: 104.67 s
Wall time: 114.83 s
а 10000x10000 долго ждать в сизифе ;-)
А вот как EPD справляется:
Python 2.7.1 |EPD 7.0-2 (64-bit)| (r271:86832, Nov 29 2010, 13:51:37)
Type "copyright", "credits" or "license" for more information.
IPython 0.10.1 -- An enhanced Interactive Python.
? -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help -> Python's own help system.
object? -> Details about 'object'. ?object also works, ?? prints more.
In [1]: from numpy.linalg import *
In [2]: from numpy.random import *
In [3]: from numpy import dot
In [4]: m1=randn(5000,5000)
In [5]: %time m2=randn(5000,5000)
CPU times: user 1.86 s, sys: 0.07 s, total: 1.93 s
Wall time: 1.93 s
In [7]: %time m3=dot(m1,m2)
CPU times: user 27.88 s, sys: 0.08 s, total: 27.95 s
Wall time: 16.12 s
Как говорится почувствуйте разницу ;-).
