pip install joblib 1. Step 2: 创建并启动并行任务 接下来,你需要创建并启动你的并行任务。以下是一个简单的例子: from joblib import Parallel, delayed#定义一个简单的函数def square(x): return x*x#创建一个并行任务results = Parallel(n_jobs=-1)(delayed(square)(i) for i in range(10)) print(r...
在脚本开始处添加以下代码: fromjoblibimportParallel,delayed 1. 3. 创建并行任务 接下来,我们需要创建需要并行执行的任务。可以使用 Parallel 和 delayed 函数来定义并行任务。例如: defsquare(x):returnx*x inputs=[1,2,3,4,5]results=Parallel(n_jobs=-1)(delayed(square)(i)foriininputs) 1. 2. 3....

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 "...
Parallel(n_jobs=32)是什么用法 讲的相当不错 delayed(score_model) 相当于什么? 相当于score_model 因此,后边必须跟函数的参数 (data, n_test, cfg) delay干的事儿就是,保留了要执行的函数,以及函数对应的参数; 请复习,**kwargs的用法。 装饰器

Hello, I'm trying to parallelize an operation on the columns of pandas dataframe using joblib, using this logic: parallel = Parallel(n_jobs=-1, backend='multiprocessing', verbose=12); joblist = [delayed(myfunc)( df[col] ) for col in colu...
