in datautils/README.md：
“Have a look at util/playdata.py”

in playdata.py：
“parser.add_argument('--dataset_path', type=str, default='../extract')”

[shiwanghua]

in playdata.py：

dataset = DataBaseCrossCompiler('../extractDataset/coreutils', ["coreutils-b2sum"], False, ['O0', 'Os'])

what's the “../extractDataset” directory ? Is it "../extract" ?
