Unhandled exit code when loading Nifti with SimpleITK in python

Question

I am trying to load .nii.gz files using SimpleITK in python using PyCharm. Ideally, ITK has a NIFTI class and I followed these tutorials, so I presume SimpleITK has a wrapper for NIFTI class in ITK. The issue is I get a weird exit code which has no documentation (as per google) like this

Process finished with exit code -1073741819 (0xC0000005)

The code is as simple as it gets :

import numpy as np
import SimpleITK as sitk

image = sitk.ReadImage(filename)
imageSize = image.GetSize()

I also tried using nibabel library to load the same image format but I always get a MemoryError, even though, TaskManager (not the best approach) says I have sufficient memory.

The file is ~123 Mb. Any help would be appreciated!

Can you share your file? What other applications are you able to open your file with? Please try slicer3D or ITKsnap. — blowekamp
Unfortunately, due to research purposes I can't share the file. I can open it with slicer3D and ITKsnap but I want to load it with python for automatic segmentation. It is around ~123 Mb as I said. I also want to point out that I am using python 32 bit on a 64 bit machine. This is because I couldn't load sitk in 64. — Rick M.

So to anyone who might land onto this problem, it was an issue with the version of python. I was using 32 bit Python on a 64 bit Windows PC, when I changed it to 64 bit Python and installed the wheels files here, the strange exit code was gone. I would also recommend following this.
