有没有办法在 IPython notebook 中同时运行多个单元? [英] Is there a way to run multiple cells simultaneously in IPython notebook?

问题描述

我笔记本中的一个单元执行了很长时间，而机器中的其他 CPU 处于空闲状态.是否可以并行运行其他单元?

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

是的.这里是 ipyparallel(以前的IPython)的文档parallel) 将向您展示如何生成多个 IPython 内核.在您可以自由地跨内核分配工作后，您可以使用 %%px0 %%px1... %%px999 为单元格添加前缀(一旦设置)在特定引擎上执行单元，这实际上对应于单元的并行执行.我建议您也看看 Dask.

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 at Dask as well.
