manager.py  文件的 line 139, in wait_for_ack 相关语句注释掉

    def wait_for_ack(self):  # no cov
        misses = 0
        while not self._all_workers_ack():
            sleep(0.1)
            misses += 1
            # if misses > self.THRESHOLD:
            #     error_logger.error("Not all workers are ack. Shutting down.")
            #     self.kill()
