sklearn.utils.parallel_backend(backend, n_jobs=-1, inner_max_num_threads=None, **backend_params) 在with 块中更改 Parallel 使用的默认后端。 如果backend是一个字符串,它必须与先前使用register_parallel_backend函数注册的实现相匹配。 默认情况下,以下后端可用: ‘loky’:单主机、基于进程的并行性(默认使...
result = Parallel(n_jobs=-1, backend="loky")(delayed(process_data)(d) for d in data) ``` 在上述示例中,首先定义了一个 process_data 函数,用来处理数据。然后将待处理的数据放入一个列表中,并使用 Parallel 函数以及 delayed 函数将 process_data 函数应用于每个数据。最后,将 parallel 参数设置为 "...
backend:选择的后台并发类型(建议使用loky) loky: 默认值,第一次程序运行时会创建 n_jobs个loky进程(每次并发时都是这些loky进程进行消费),要多耗费一些时间(1-2s左右),后续不会耗费; 每个loky进程的生命周期在 最后一个请求进来后没有消费的300s后自动被杀死; multiprocessing:多进程,基于进程池(multiprocessing.P...
Hello, Thank you for your very good libs :-) In association with Celery Task Queue and MongoDB it is pure happiness! Describe the bug When I use the parameter n_jobs = 10, I get a warning message from joblib and the job is only done in o...

n_jobs below -1, (n_cpus + 1 + n_jobs) are used. Thus for n_jobs = -2, all CPUs but one are used. None is a marker for 'unset' that will be interpreted as n_jobs=1 (sequential execution) unless the call is performed under a parallel_backend context manager that sets another...
Parallel参数众多,但常用的基本只有n_jobs和backend参数。 3.2.2 n_jobs: int, default: None —— 设置并行执行任务的最大数量。 当backend="multiprocessing"时指python工作进程的数量,或者backend="threading"时指线程池大小。当n_jobs=-1时,使用所有的CPU执行并行计算。当n_jobs=1时,就不会使用并行代码,即...
