How can I analyze a file created with pstats.dump_stats(filename) off line?

Question

I have essentially done the following:

import cProfile, pstats, StringIO
pr = cProfile.Profile()
pr.enable()
# ... my code did something ...
pr.disable()
s = Str

You can try snakeviz https://jiffyclub.github.io/snakeviz

It is a browser based graphical viewer for the output of Python’s cProfile module and an alternative to using the standard library pstats module.

# to install it with pip
pip install snakeviz

# once installed, you can use snakeviz to view the file
snakeviz /path/to/your/dump/pstat/file

Here is a sample image for a visualized pstat file you can dump like above.
