Michael is the developer behind the super-cool tool, CprofileV.” Michael, known as ymichael on GitHub, a software engineer at Figma
“cprofilev” simplifies the usage of Python’s cProfile
module for profiling code and provides a web-based HTML view of the profiling statistics. Here’s a summary of the key points:
- Purpose: “cprofilev” makes it easier to use Python’s
cProfile
for profiling Python programs. Profiling is a technique used to measure code execution time and identify bottlenecks in the code for performance optimization. - Installation: You can install “cprofilev” using pip, a package manager for Python. On most UNIX-like systems, you’ll likely need to use sudo or run as root to install it:
pip install cprofilev
Code language: Python (python)
- Quickstart: To profile your Python program with “cprofilev,” you can run it using the
-m cprofilev
flag:
python -m cprofilev /path/to/python/program ...
Code language: Python (python)
This command starts profiling your program and makes the statistics available in a web-based interface. You can access this interface at http://localhost:4000 while your program is still running.
Alternatively, you can save the cProfile output to a file and later analyze it with “cprofilev” using the -f
flag:
python -m cProfile -o /path/to/save/output /path/to/python/program ...
cprofilev -f /path/to/save/output
Code language: Python (python)
- Usage: “cprofilev” provides a command-line interface with the following options:
scriptfile
: The Python script file to run and profile.-h
,--help
: Show 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
: Specify a cProfile output file to view. If specified, thescriptfile
provided will be ignored.
For more detailed information and examples on how to use “cprofilev,” you can refer to the documentation: http://ymichael.com/2014/03/08/profiling-python-with-cprofile.html.
