New submission from MattyG <[email protected]>:
from numpy import *
import cPickle
a = zeros((300000, 1000))
f = open("test.pkl", "w")
cPickle.dump(a, f)
------
SystemError: Traceback (most recent call last)
/home/kddcup/code/matt/svd-projection/take5/<ipython console> in <module>()
SystemError?: error return without exception set
Or using the .dump function:
a.dump("test.pkl")
SystemError? Traceback (most recent call last)
/home/kddcup/code/matt/svd-projection/take5/<ipython console> in <module>()
SystemError: NULL result without error in PyObject?_Call
I am not sure if this is a numpy or Pickle/cPickle glitch. In either case, even
if this is a semi-known behavior, a more instructive error message would
certainly help. I think the problem only happens for arrays larger than
2**(32-1) bytes but I would have to experiment more to be sure.
