ZeroDivisionError: float division by zero

[cpys]

when i try to render the svg file by myself, i got exception like this

  File "profmiddleware.py", line 37, in post_prof
    flameprof.render(pr.stats, flameprof.get_out(svg_file_name))

flameprof.render(pr.stats, flameprof.get_out(svg_file_name))

flameprof==0.4

[cpys]

if r equals ('python3.8/site-packages/urllib3/util/wait.py', 127, 'wait_for_socket'), to equals ('python3.8/site-packages/urllib3/util/wait.py', 114, '_have_working_pll'), then calls[(r, to)] equals (0, 0, 0.0, 0.0)

I have the same problem, have you solved it?

[maccinza]

I am facing the same issue. Any solutions or is it a matter of the file not being usable by flameprof?

[rudin-jiang]

same issue...

[roversch]

Every time I use flameprof, I get this error. Did anyone find out what is causing this?

[dev0Guy]

I've the same problem.
Will update on fix

I encountered the same issue, but I think it might not be a problem with flameprof. It could be related to the solver environment. This issue occurs in the py312 environment, but it works fine when I switch back to the 311 environment.
Additionally, I found that using py-spy for performance analysis also works abnormally in py312. It cannot capture the Python process.

I also have the same problem. Any advices here?

[imk-asyk]

same problem (3.12.4) solved by adding a small float after sum

same problem (3.12.4) solved by adding a small float after sum

This is the way!
