How can I view how much time each cell took to run in a Jupyter notebook?

Question

After I select run all, run all above, or run all below in a Jupyter notebook, how can I view how much time each cell took to run?

My question is different from Simple way to measure cell execution time in ipython notebook as I want the running times for all cells, not just one. I.e., if the notebook contains 10 cells I want 10 running times.

Answer 1

Install and enable ExecuteTime nbextension: "Display when each cell has been executed and how long it took".

Installation and configuration details are here.

Answer 2

I believe only by putting magic function %%time
