python - how to optimize multiprocessing in this code? -


results big variable , do:

results = sum(results, []) print 'writing results json %s' % res_file open(res_file, 'w') f:     json.dump(results, f, sort_keys=true, indent=4)

for it. how store big variable in generate process?

pool = mp.pool(8) results = pool.map(coco_results_one_category_kernel, data_pack) pool.close() pool.join()

this code cannot allocation memory multiprocessing:

oserror: [errno 12] cannot allocate memory

results = [] in range(len(data_pack)):      print i,'/',len(data_pack)      results.append(coco_results_one_category_kernel(data_pack[i])) results = sum(results, [])

this code kiilled when i=36 because of result big. how can this? donot care time, result variable..

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
