li-js/line_profiler_example

A simple example of performing line-by-line time profiling in python

Install the profiler

The line profiler is from https://github.com/rkern/line_profiler.git.

pip install line_profiler

Note that it will install a binary command ''kernprof'' and a python library module ''line_profiler''.

Run and convert the original python file

kernprof -l example.py 

Note that @profile decorator is used to define the functions we want to perform profiling in the python script. The output file after the execution is example.py.lprof.

Get the profiled results

python -m line_profiler example.py.lprof
