Dear all,
I get the following memory error while running my program:
*Traceback (most recent call last):
File
"/home/nistl/Software/Netzbetreiber/FLOW/src/MemoryError_Debug.py", line
9, in <module>
correlation = corrcoef(data_records)
File "/usr/lib/python2.7/dist-packages/numpy/lib/function_base.py",
line 1992, in corrcoef
c = cov(x, y, rowvar, bias)
File "/usr/lib/python2.7/dist-packages/numpy/lib/function_base.py",
line 1973, in cov
return (dot(X, X.T.conj()) / fact).squeeze()
MemoryError*
Here an easy example how to reproduce the error:
*#!/usr/bin/env python2.7
from pybinsel import open
from numpy import *
if __name__ == '__main__':
data_records = random.random((459375, 24))
correlation = corrcoef(data_records)
*My real data has the same dimension. Is this a size problem of the
array or did I simply make a mistake in the application of corrcoef?
I hope that you can help me! Thanks!
Best regards,
Nicole Stoffels
