我可以在 Jupyter 笔记本中运行一个单元，而另一个单元正在运行吗？

Question

As the title says, is there a way to run a Jupyter Notebook cell in the background (in Python)?

For example, is there a hypothetical magic command %%run_in_background that allows me to kick off a cell to execute in the background without blocking other cells from executing.

Answer 1

Technically you can't do that, each kernel is like an instance of python, you can only run a script at a time.

You could run the cell, then refresh the browser and run the notebook fresh. The previous command will continue running but there is no way of accessing it in the notebook anymore. You won't get the result you want, the output from the previous run won't appear in this new instance.

Your best bet is to use 2 different notebooks, or 2 python scripts or use multiprocessing modules.
