Here are the commands as macro form, for easy cut and paste into pylab: import gc import matplotlib.cbook as cbook data = ones((1500,1500,3)) hold(False) imshow(data) gc.collect() cbook.report_memory() imshow(data) gc.collect() cbook.report_memory() imshow(data) gc.collect() cbook.report_memory() imshow(data) gc.collect() cbook.report_memory() > > > ------------------------------------------------------------------------------ > This SF.net email is sponsored by Sprint > What will you do first with EVO, the first 4G phone? > Visit sprint.com/first -- http://p.sf.net/sfu/sprint-com-first ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
