Version: joblib==1.0.1 Pandas: pandas==1.3.0 Numpy: numpy==1.21.0 Dask: dask==2021.6.2, distributed==2021.6.2 I have the following code, which works fine when there's only 1 worker in my Dask cluster: with parallel_backend("dask"): results = Parallel(n_jobs=-1, verbose=10)( de...

parallel_obj = Parallel(n_jobs=-1, verbose=0, backend='loky', timeout=10) 1. 使用时的问题: 问题1:接口在处理时 会出现 耗时不稳定的情况(10%概率) 原因:在使用 backend='loky'时,其自动生成loky的worker进程,消费任务;但其机制 在最后一次消费后 如果300s内没有消费为了节省系统资源,会自动杀掉wo...
n_jobs:并行运行的任务数量,设为-1会使用所有可用的处理器核心。 backend:指定并行方式,可以选择进程(multiprocessing)或线程(threading)。 verbose:控制输出的详细程度,值越高输出越详细。 Mermaid旅行图 接下来,我们用Mermaid语法展示一个简单的旅行图,表示进行并行计算的步骤。
