Wow! This video was chock-full of all kinds of amazing info and tools 🤩🙌🏼 Loved the part about .har files and the yelp-gprof2dot, as well as your quick explanation of how to strip the formatting/style info and just understand the general form of the dot files (for the graph). 🙌🏼 Thank you

Awesome stuff. I imagine this is also what the pycharm integrated profiler is based on, they look really similar. Learning a lot by the way. cheers mate

very helpful - thanks

Thanks. I think it will help me a lot. I'm trying to repeat the steps you did in the video but it fails on calling dot. There is no "dot" in my $PATH. I've installed graphviz to my venv but still no dot =(

@anthonywritescode 3 года назад

the pypi `graphviz` project is not associated with the actual graphviz project -- dot comes from the core graphviz project (for example from apt-get install graphviz): $ dpkg -S $(which dot) graphviz: /usr/bin/dot

@horseinthesky 3 года назад

@@anthonywritescode Thanks again. Works great =)

Have you tried snakeviz?

@anthonywritescode 4 года назад

yeah I have, it has a lot of viz modes but I find they're harder to drill into :shrugs:

@TarunSharma-ml3ih 2 года назад

hey , i executed this command in my rhel 7 : "gprof log.pstats | babi -" and I am getting this error,please help me with this : "gprof: log.pstats: not in executable format babi: Command not found."

@anthonywritescode 2 года назад

I didn't use `gprof` -- I used `gprof2dot`. also if you don't have `babi` installed you won't be able to run `babi` of course!

@con-f-use Год назад

To do a bit of grave-digging: Are you still using gprof2dot and dot or what would you recommend today? I've been using evanhempel's python-flamegraph a bit, but not really settled on any performance vis tool for python yet. SnakeViz sounds promising too or KCacheGrind (with pyprof2calltree).

@anthonywritescode Год назад

I still use this same toolset yes
