I have this simple NumPy/Python code below:
from numpy import zeros, float32
v = 3039345
d = 400
i = 354993
j = 0
var1 = zeros((v,d), dtype=float32)
var1[i, j] = 0 #the problem pops here
when the last line is interpreted, I have this:
Process finished with exit code -1073741819 (0xC0000005)
If i < 354993 the execution is fine. I am using Python 2.7 32-bit over Windows 8 64-bit. It is due to a limit in Memory? in this case what would be the best solution to have this working?
It is caused by the 32 bit version of numpy binaries. Numpy does calculate the size of the allocated memory region using platform-specific integers, and the size of the array measured in bytes does not fit in 2**32. It sounds like a bug, as it should raise an error at array creation in my opinion.
You can install 64 bit version of any python and numpy, and that will fix your problem.
