问题描述
我的笔记本中的一个单元格执行了很长时间,而机器中的另一个单元格处于空闲状态。是否有可能并行运行其他单元格?
One cell in my notebook executes for a long time, while the other CPU's in the machine are idle. Is it possible to run other cells in parallel?
推荐答案
不是神奇的,可能不是你的想法但是是的。 ipyparallel
的文档(以前 IPython parallel
),它将向您展示如何生成多个IPython内核。在您可以跨核心分发工作后,您可以使用 %% px0
%% px1
为单元格添加前缀。 .. %% px999
(一旦设置)执行特定引擎上的单元格,这实际上对应于单元格的并行执行。我建议你看看。
Not magically, and probably not what you think but yes. Here is the documentation for ipyparallel
(formerly IPython parallel
) that will show you how to spawn multiple IPython kernel. After you are free to distribute the work across cores, and you can prefix cells with %%px0
%%px1
... %%px999
(once set up) to execute a cell on a specific engine, which in practice correspond to parallel execution of cell. I woudl suggest having a look as Dask as well.
