脚本模式下，用多进程跑策略报错：
找不到数据服务驱动vnpy_，使用默认的RQData数据服务

源代码如下：

import multiprocessing
from vnpy_scripttrader import init_cli_trading
from vnpy_ctp import CtpGateway

class Strategy:
    def __init__(self,engine = init_cli_trading([CtpGateway])) -> None:
        self.engine = engine

    def stratrgy(self):
        print('111')

def main():
    commodities = Strategy()

    p1 = multiprocessing.Process(target=commodities.stratrgy)
    p2 = multiprocessing.Process(target=commodities.stratrgy)
    p1.start()
    p2.start()

if __name__ == '__main__':
    main()

后面解决这个问题了吗 我也遇到了

开源版本没有提供多进程支持，目前只有elite版本提供了多进程支持
