<br>
I was able to execute the following on my RH6 x64 system from a locally built SimpleITK:<br>
<br>
img = sitk.Image([2048]*3,sitk.sitkUInt16)<br>
a = sitk.GetArrayFromImage(img)<br>
<br>
Are you able to do a similar test?<br>
<br>
There are two things that I am suspicious of the first is the type of image you have. Please look at the following:<br>
<br>
print img.GetPixelIDTypeAsString()<br>
print img<br>
<br>
This should give you the details of the run-time image information.<br>
<br>
If happen to have a RGB image loaded as a Vector image, that is a bit different that just a scalar UInt16.<br>
<br>
The second possible issue is that there is a binary incompatibility issue with your OS and the version you download. So what are the specifics of the OS you are using and the python version?<br>
<br>
