Jupyter Notebook时间分析 [英] Jupyter Notebook time profiling

问题描述

所以我通过anaconda安装了jupyter笔记本，并且正在使用python 3内核.

So I installed jupyter notebook through anaconda and I am working on python 3 kernel.

我正在尝试使用%time魔术命令进行时间剖析，如show 在这里 问题在于它仅显示 Wall Time (挂墙时间)，而不显示 CPU时间

I am trying to do Time profiling using %time magic command as show here The problem is that it only prints the Wall Time not the CPU Time

使用%time或%%time没有帮助

• %time仅为第一行打印墙壁时间
• %%time打印整个单元格
的壁挂时间

• %time prints the wall time for the first line only
• %%time prints the wall time for the whole cell

我不确定是否有任何特定配置来打印CPU时间

I am not sure if there any specif config to print the CPU time

编辑

为明确起见，使用%%time应该为整个单元格

To clarify using %%time should print two metrics for the whole cell

• 指标1 :CPU时间
• 指标2 :挂墙时间

• Metric 1: CPU Times
• Metric 2: wall time

我的问题是我只得到墙壁时间而不是CPU时间.

my problem is that I only get wall time not CPU time.

您可以查看此链接以了解预期的输出是什么对于%%time

You may check this link on what is the expected output for %%time

推荐答案

所以我的问题似乎在环境本身中.

So it seems that my issue was in the environment itself.

从Windows切换到Ubuntu实际上帮助我打印了 CPU时间.

Switching from Windows to Ubuntu actually helped me print the CPU times.
