python - How to limit memory usage ofPython _ pandas -

-

currently using panda operation merge 2 csv file take around 4.6 gb ram want limit ram usage 2 gb java -xmax , -xmin

is way so

thanks in advance

use setrlimit:

import resource  rsrc = resource.rlimit_data soft, hard = resource.getrlimit(rsrc) print 'soft limit starts  :', soft  resource.setrlimit(rsrc, (1024, hard)) #limit 1 kilobyte  soft, hard = resource.getrlimit(rsrc) print 'soft limit changed :', soft

edit: actually, i'm not sure if setrlimit controls cpu or ram usage. shell, make use of ulimit:

ulimit -v 128k python script.py ulimit -v unlimited

edit: please note linux systems, , i'm not sure how this, or if it's possible on windows.
