I'm on a windows 7 64 bit machine with 8GB of memory and running a 32bit python program. The programs reads a 5,118 zipped numpy files (npz). Windows reports that the files take up
Python Max Heap Size
1.98 GB on disk Each npz file contains two pieces of data: 'arr_0' is of type np.float32 and 'arr_1' is of type np.uint8 The python script reads each file appends their data into two lists and then closes the file. Around file 4284/5118 the program throws a MemoryException However, the task manager says that the memory usage of python.exe *32 when the error occurs is 1,854,848K ~= 1.8GB. Much less than my 8 GB limit, or the supposed 4GB limit of a 32bit program. In the program I catch the memory error and it reports: Each list has length 4285. The first list contains a total of 1,928,588,480 float32's ~= 229.9 MB of data. The second list contains 12,342,966,272 uint8's ~= 1,471.3MB of data. So, everything seems to be checking out. Except for the part where I get a memory error. I absolutely have more memory, and the file which it crashes on is ~800KB, so its not failing on reading a huge file. Also, the file isn't corrupted. I can read it just fine, if I don't use up all that memo

It is similar to: why does arcpy function work in ArcMap python window but not from stand-alone script? except that the answer to that question does not apply to me. I also am not just running a function from my script in the python window. I am running python idle memory the exact same script. There is also Script runs in ArcMap Python window but not in stand alone Python win or IDLE but no great answer there. I suspect it has something to do with Geoprocessing Options (my specific hunch is "background processing"?) that may not apply when I'm using IDLE (see last screenshot) but I'd really like to know what specifically causes this so I can run scripts like this from IDLE (and not from ArcMap every time). Is there a way to set options like this in the script? I am using 10.3.1 so I assumed what I've read about needing to install background processing no longer applies. I wrote this script to process contours from a series of smoothed DEMs. I was surprised when it crashed when running it in IDLE after successfully testing on a small subsample. On the full-sized project data, it crashed before successfully creating the first set of contours (1/17) and the result was unfinished (big gaps of contour lines missing). Just for grins, I turned to the Python window in an open ArcMap session and ran it with the "execfile" command and lo and behold it is running as I write this up (appears now to be almost done). This screenshot shows that it crashed at the shell and also shows two successful sets of contours in the data frame in the backgroun
