Usage

Multiprocessing SyncManager

Open server first:

$ spr start-server

The defualt port 50001.

(Process1) productor:

from sparrow.multiprocess.client import Client

client = Client(port=50001)
client.update_dict({'a': 1, 'b': 2})

(Process2) consumer:

from sparrow.multiprocess.client import Client

client = Client(port=50001)
print(client.get_dict_data())

>> > {'a': 1, 'b': 2}

Common tools

• Kill process by port

$ spr kill {port}

• pack & unpack
  support archive format: "zip", "tar", "gztar", "bztar", or "xztar".

$ spr pack pack_dir

$ spr unpack filename extract_dir

• Scaffold

$ spr create awosome-project

Some useful functions

sparrow.relp

sparrow.performance.MeasureTime
For measuring time (including gpu time)

sparrow.performance.get_process_memory
Get the memory size occupied by the process

Safe logger in multiprocessing

from sparrow.log import Logger
import numpy as np

logger = Logger(name='train-log', log_dir='./logs', )
logger.info("hello", "numpy:", np.arange(10))

logger2 = Logger.get_logger('train-log')
print(id(logger2) == id(logger))
>> > True
