一般连续两个目录也就是差不错70张左右不用下载的时候,程序就崩溃了。报ValueError: Pool not running错误。 2、我用KeyboardInterrupt捕捉中断,但是用了Pool以后就不起作用了 except KeyboardInterrupt: print('运行中断ctrl+c') with open('didload.txt','w') as ff: ff.write(','.join(didload)) 可以捕...
而下个循环,即i=1时,该进程池对象又试图添加进程,所以会出错:pool not running,意味着你的进程池不在运行中,因为你的pool在i=0的循环中,已经关闭并且执行完毕所有的进程,该pool的生命周期已经结束了。 所以你的代码应当写为 pool = multiprocessing.Pool() for i in range(0, len(data()[0])): for j ...
