text files. As I read in the lines and process them, I append(dataline) to a list. At some point the append() generates a Memory Error exception. However, watching the program run in the Windows Task Manager, at the point of the crash I see 4.3 GB available and 1.1 GB free. Thus, I do not understand the reason for the exception. Python version is 2.6.6. I guess, the only reason is that it is not able to use memory error pandas more of the available RAM. If this is so, is it possible to increase the allocation? python list memory share|improve this question asked Dec 14 '10 at 17:07 Pete 5,12062140 1 Try using a 64-bit build of Python. Though if you are using any extension modules, they'll then need to be built 64-bit as well. –Adam Vandenberg Dec 14 '10 at 17:08 Can you print the MemoryError exception string? That should give us more info. –chrisaycock Dec 14 '10 at 17:10 Are you appending before or after you process the lines? –nmichaels Dec 14 '10 at 17:15 @nmichaels- looks like this: data.append(processraw(raw)). each raw is one line. –Pete Dec 14 '10 at 17:36 Show us more code and maybe we will be able to show you how to improve your memory consumption. How big is your set of text files? @aix is right about 32-bit versus 64-bit. –kevpie Dec 14 '10 at 18:01 add a comment| 5 Answers 5 active oldest votes up vote 19 down vote accepted If you're using a 32-bit build of Python, you might want to try a 64-bit version. It is possible for a process to address at most 4GB of RAM using 32-bit addresses, but typically (depending on the OS), one gets much less. It sounds like your Python process may be hitting this limit. 64-

I perform calculus that I put in a list of 20301 elements (=one row of my matrix). I need all those data in memory to proceed next Markov step but i can store them elsewhere (eg http://stackoverflow.com/questions/5537618/memory-errors-and-list-limits file) if needed even if it will slow my Markov chain walk-through.

program using Python 2.5.4 in windows 32 OS. The amount of data it works with is huge. I have managed to keep memory footprint low, but have found that, independent of the physical RAM of the machine, python always gives the MemoryError message when it has occupied exactly only 2.2 GB. I have tested this in 4 different machines, all with memory of 3 to 4 GB... I'm amazed.Could any of you please help me to figure out how to change that limit? I typed help(MemoryError) and it is a class itself, but that help told me nothing I can use...Thanks,Angelica. reply Tweet Search Discussions Search All Groups Python python-list 17 responses Oldest Nested Chris Kaynor A 32 bit app can only use 4 GB of memory itself (regardless of the amount of system ram), the OS claims some of this for the system, dlls occupy some of it, etc. As such, the app can only really use a smaller subset (generally between 2 to 3 GB, depending upon the app and the OS).
