I've been using a python script to calculate the average values http://stackoverflow.com/questions/4285185/upper-memory-limit from a file which is a minimum of 150mb big. Depending on the size of the file I sometimes encounter a MemoryError. Can more memory be assigned to the python so I don't encounter the error? EDIT: Code now below NOTE: The file sizes can vary greatly (up to 20GB) the minimum size of the a file is 150mb file_A1_B1 = open("A1_B1_100000.txt", "r") file_A2_B2 = open("A2_B2_100000.txt", "r") file_A1_B2 = open("A1_B2_100000.txt", "r") file_A2_B1 = open("A2_B1_100000.txt", "r") file_write = open ("average_generations.txt", "w") mutation_average = open("mutation_average", "w") files = [file_A2_B2,file_A2_B2,file_A1_B2,file_A2_B1] for u in files: line = u.readlines() list_of_lines = [] for i in line: values = i.split('\t') list_of_lines.append(values) count = 0 for j in list_of_lines: count +=1 for k in range(0,count): list_of_lines[k].remove('\n') length = len(list_of_lines[0]) print_counter = 4 for o in range(0,length): total = 0 for p in range(0,count): number = float(list_of_lines[p][o]) total = total + number average = total/count print average if print_counter == 4: file_write.write(str(averag
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] I was amazed by the response of the Python community. Hats off to all. https://mail.python.org/pipermail/tutor/2008-July/063364.html I stopped using the lists and got the issue resolved using just the variables. Nevertheless, i learned a lot by starting this thread. Thanks a million to Alan, Chris, John for spending your https://geonet.esri.com/thread/96491 quality time in helping this newbie. Hope i havent spoiled Alan's sleep much. On 7/29/08, tutor-request at python.org

I have rasters representing monthly rainfall and evapo-transpiration going back over 4 decades, together with information on soil properties etc.My script loops over all of my time-series data and writes the output rasters to a folder on my hard disk. It works fine when I use only a sub-set of the data, but with the whole lot I get a "Memory error" (nothing more helpful unfortunately). I can't easily run my code in chunks as the output from each loop is fed into the next loop as the input; it'd be nice to do it all in one go.When I watch my code run in the task manager it clearly releases most of the memory that has been used at the end of each loop, but a small amount is not released and the memory usage grows over time. I'm trying to pin this down, but I'm fairly new to all this and the deeper I dig the more confused I get! As far as I can tell from the forums, there are three main possibilities (feel free to add more!):1. The geoprocessor is leaking memory,2. My python code (lots of numpy algebra) is leaking memory,3. I'm trying to write too many rasters into a workspace and there's some kind of limit I don't know about.For 1, I've read on the forums that the geoprocessor can leak memory. Most of these posts relate to older versions of the gp - have all of these problems been solved for version 9.3? My code actually makes very little use of the geoprocessor anyway: within each loop, I use gp.Resample_management twice and gp.AddMessage once. Is this enough to cause a serious memory leak over many iterations? Some of the forum posts give me the impression that gp memory leaks are characterised by continuously increasing memory consumption and a decrease in processing speed - is this right? My code memory usage oscillates and grows slowly, the processing speed only decreases slightly during runtime.For 2, I don't really know where to start. My code uses the excellent M
