[SciPy-user] scipy on old CPU crashes
Tue Dec 2 01:36:12 CST 2008
sorry, but scipy-0.7.0b1-win32-superpack-python2.4.exe and
numpy-1.2.1-win32-superpack-python2.4.exe crash on my old pc too,
which uses duron 750MHz. So now I think it is not the problem with
is there any method to find out the real reason except to compile from
(I know Duron is too old, but currently I don't have the money to buy
a new PC or even update it :( so bad)
from scipy.integrate import quad
print quad(lambda x:x, 1, 2) #crash soon
