Mypy 2.0 Relased

Mypy 2.0이 릴리스되어 병렬 및 점진적 타입 검사, 기본 활성화된 --local-partial-types 및 --strict-bytes 옵션, 그리고 Python 3.9 지원 중단 등 주요 기능 개선과 성능 향상을 포함한다. 특히 병렬 타입 검사 기능은 대규모 프로젝트에서 최대 5배 속도 향상을 제공하며, 새로운 네이티브 파서와 함께 작동한다. 또한, 타입 재정의 동작 변경, 메모리 누수 수정, 오류 메시지 개선 등 다양한 버그 수정과 기능 개선이 포함되었다. 이번 릴리스는 Python 타입 검사 도구로서 실무에 즉시 적용 가능한 중요한 업데이트다.

很多 Python 加速的方法

#c #code #codon #compiler #cpython #cython #graalpy #jax #mojo #mypyc #native #numba #numpy #performance #pyo3 #pypy #python #rust #speed #taichi

So if I take ordinary #python (no math to speak of) and

#cythonize it
#mypyc it

No obvious pattern on if it is faster or not. I don't know where the 20% to 200x rule of thumb came from (that I've seen in various conference talks)

I've been trying every x months to speed up #python with native code. This weekend with half-assed effort I got a rust + python thing going.

The magic: #maturin + #pyo3

- c, go, c++, #cython - failed because the difficult level of dealing with the build scripts. And c, c++ are just nasty.
- #mypyc - Almost worked, but failed, the annotations have to be a perfect subset of what mypyc can handle.

Mypyc and cython need something like maturin if they want get widespread adoption.

People out here sleepin' on mypyc.

The lengths to which people go to squeeze a bit of #performance out of #Python 😰:
