cprofilev runs and profiles a given python program and outputs a simple html view of the statistics collected.
See: http://ymichael.com/2014/03/08/profiling-python-with-cprofile.html on how to make sense of the profiled statistics.
on most UNIX-like systems, you'll probably need to run the following `install` command as root or by using sudo
pip install cprofilev
- Simply run your python program in with the -m cprofilev flag.
$ python -m cprofilev /path/to/python/program ...
- Navigate to http://localhost:4000 to view profile statistics of your python program (even while its still running!)
Alternatively you can output view cprofile output using the -f flag:
# NOTE this is cProfile not cprofilev $ python -m cProfile -o /path/to/save/output /path/to/python/program ... $ cprofilev -f /path/to/save/output
usage: cprofilev.py [--version] [-a ADDRESS] [-p PORT] scriptfile [arg] ... An easier way to use cProfile. positional arguments: scriptfile The python script file to run and profile. optional arguments: -h, --help show this help message and exit --version show program's version number and exit -a ADDRESS, --address ADDRESS The address to listen on. (defaults to 127.0.0.1). -p PORT, --port PORT The port to listen on. (defaults to 4000). -f FILE, --file FILE cProfile output to view. If specified, the scriptfile provided will be ignored.
bottle: used for serving the html page.
To quickly contribute to cprofilev, you can use this example as a means to profile things:
