我想通过Pool.map()将关键字参数传递给我的worker-function.在搜索论坛时,我找不到一个明确的例子.

示例代码:

import multiprocessing as mp

def worker((x,y), **kwargs):
    kwarg_test = kwargs.get('kwarg_test', False)
    print("kwarg_test = {}".format(kwarg_test))     
    if kwarg_test:
        print("Success")
    return x*y

def wrapper_process(**kwargs):
    jobs = []
    pool=mp.Pool(4)
    for i, n in enumerate(range(4)):
        jobs.append((n,i))
    pool.map(worker, jobs) #works
    pool.map(worker, jobs, kwargs) #how to do this?   

def main(**kwargs):
    worker((1,2),kwarg_test=True) #accepts kwargs
    wrapper_process(kwarg_test=True)

if __name__ == "__main__":    
    main()

输出:

kwarg_test = True
Success
kwarg_test = False
kwarg_test = False
kwarg_test = False
kwarg_test = False
TypeError: unsupported operand type(s) for //: 'int' and 'dict' …
