Шпаргалка по инференсу на С++

Если ты только погружаешься в работу с инференсом на C++ и тебе интересно получить представление о том, как можно собирать и запускать популярные ML-библиотеки, то я рад поделиться базой, которую я использую в своих проектах. Здесь ты найдёшь простые проекты, решающие основные ML-задачи, и немного теории к этому коду. Надеюсь, что приведённый код может стать первой рабочей версией для новых фич в твоих проектах.

Are you one of the 10'000s of #CXX #Python developers using #pybind11? Do you care about great #autodocs and #autocompletion in #interactive workflows?

The pybind11-stubgen project seeks support in #maintaining it! We #pybind11 maintainers would move it to the #pybind mainline org, but we need a community to help support the .pyi stub generator <3

Does anyone know of a good overview how much overhead using ctypes to call functions from a dynamic library adds to #python code instead of building a native extension e.g via #cython #pybind11 or #nanobind ?

A blog post with some statistics would be perfect but just ballpark figures from anyone who knows what they are talking about is fine

專注在學習的時候，
我們常會為了紀錄與分享而書寫，
不帶其它目的。
學到一項新事物，找到一個新工具，
覺得好方便、好有趣，
趕快寫一篇推文脆文，讓大家都知道。
這是很多程式員的心情寫照。

寫了幾十年程式以後，雖然這種分享的心情還在，
但不得不承認淡了一點。

最近被問到一個 #pybind11 caster 的問題，
比手畫腳地講了半天以後，
才猛然想起三年多前有寫過一篇筆記：
https://yyc.solvcon.net/en/latest/writing/2021/pyboost11/pyboost11.html
這或許是最近一次稍微基於分享的心態寫的紀錄，
雖然分享只佔了一小部分的目的。

寫下來的主要原因是怕自己忘記。
當時為了研究 pybind11 和 boost.python 的四向轉換，
追了不少程式，
我有自信不寫下來的話，一定會忘記細節。
現在一看，果不其然，
還好當年未雨綢繆，有寫清楚範例程式。

活得愈久，生活愈忙碌。
需要毅力才能找回單純為了書寫而作的書寫。

Pybind11 is pretty cool. If you need to use a Python library a lot for like finding icons or something, you can just start the interpreter when your program starts and not have it restart every time that code runs.

@cdavies I really really want to hate #python sometimes but can't. The darn thing is so useful. Nothing beats it for anything <1k loc! And no matter what you want to do, it is second or third best choice available.

But as a language for developing systems, it sucks! C-API is terrible (shoutout to #pybind11 and #maturin). Dynamic typing becomes a bane (#mypy helps). For last two days, I am tweaking a #fastapi, I miss rust type safety when refactoring.

#FOSDEM Could anyone recommend a useful resource for learning pybind11, in complement of the docs (https://pybind11.readthedocs.io/en/stable/index.html) :blobcatheart: ?

I am once again delving into the world of #meta-meta #programming..

Generate a #Python binding (#pybind11) for a C++ #binding which you generate from a #WSDL/ #XSD #SOAP service definition given you have only the WSDL at hand to start with.

I was aware this project wasn't exactly small but it's growing further. Glad my boss nodded it off as a “that's quick and easy and cheaper than licensing gSOAP!” thing.

Fun adventure profiling showed strange overhead in #pybind11.

Did a dig in and found https://github.com/pybind/pybind11/blob/48949222c637da9fc72b0ed6526ae1b40bb55237/include/pybind11/detail/internals.h#L111-L142

They are hashing and comparing strings from type_index's name if you use libc++ !?!?!

Changing to libstdc++ removed this overhead.
