Solve the following python programming problem given the following code:
def bench_apply_async_nonblocking(ntimes, stop_io_loop = False) : 
    io_loop = ioloop.IOLoop.instance () 
    def publish() : 
        time_start = time.time () 
        for i in range (ntimes) : 
            echo.apply_async (args = [i]) 
print ('non blocking apply_async called {} times in {} seconds'.format (ntimes, (time.time () - time_start))) 
        if stop_io_loop : 
            io_loop.stop () 
import tcelery 
    tcelery.setup_nonblocking_producer (celery_app = celery2, io_loop = io_loop, on_ready = stop_io_loop) 
    io_loop.start () 

    
    

    Fix the buggy line: tcelery.setup_nonblocking_producer (celery_app = celery2, io_loop = io_loop, on_ready = stop_io_loop)
