Profilers are extremely helpful tools. They help us dig deep into code, find and understand performance bottlenecks. But sometimes we just want to lay back, relax and still get a gist of the hot zones in our code.
A picture is worth a thousand words.
So, instead of presenting the data in tabular form, if presented as a heatmap visualization, it makes comprehending the time distribution in the given program much easier and quicker. That is exactly what is being done here !
- Simple CLI interface.
- No complicated setup.
- Heatmap visualization to view hot zones in code.
- Ability to export the heatmap as an image file.
- Ability to scroll, to help view heatmap of large py files.
pip install py-heat
Directly from the repository
git clone https://github.com/csurfer/pyheat.git python pyheat/setup.py install
As a command
# To view the heatmap. pyheat <path_to_python_file> # To output the heatmap as a file. pyheat <path_to_python_file> --out image_file.png pyheat --help
As a module
from pyheat import PyHeat ph = PyHeat(<file_path>) ph.create_heatmap() # To view the heatmap. ph.show_heatmap() # To output the heatmap as a file. ph.show_heatmap('image_file.png')
