Got error {OSError: [Errno 12] Cannot allocate memory} in python program?

Question

Programmer recommended to use 24GB RAM, 24processor system and 64bit OS to run the program. But I have only 4GB RAM and intel i5 3rd gen processor, and hence i got following error. So can anybody help me to solve this problem.?

"Programmer recommended to use 24GB RAM, 24 processor system and 64bit OS"



Yet you have 4GB RAM, 1 CPU and (probably) 32-bit Windows XP.



As @Francesco said buy more RAM, but also lots of CPUs, and 64-bit OS.

Answer 2

No, that link explains that there is just one issue, which is "not enough memory".



Really, I don't see the point of this question. Those who wrote the program say, "use 24 GB of memory". You neverthless choose to run with a fraction of that. Now you complain that you do not have enough memory. Please tell me what answer do you expect besides "buy more RAM".

There are several possible issues. See http://stackoverflow.com/questions/20111242/how-to-avoid-errno-12-cannot-allocate-memory-errors-caused-by-using-subprocess
