Apr 5, 2018 · There were the --abi tags cp27m and cp27mu for python 2 to distinguish between ucs2 and ucs4 unicode build flags. Those are no longer relevant in python 3 though. Use the new pip debug feature added in v19.2 to see more tag related info. Relevant github issue. –

Python packages are installed using the pipcommand, which downloads the package from pypi.org. These packages can be of two types: 1. Pure Python wheels, which may or may not be targeted to a specific Python version 2. Extension wheels, which use native code written in C/C++ All AI/ML Python packages are extension wheels that use native operating s...
AI/ML project maintainers who want to distribute the Python library with native code for Linux distros have the difficult task of ensuring ABI compatibility. The compiled code needs to run on a wide variety of Linux distributions. Fortunately, there is a way to make a binary compatible with most (though not all) Linux distributions. To do this, you...
Although the manylinux standard has helped deliver reliable and stable extension wheels, it does introduce two additional challenges: 1. Lifecycle At some point, the reference platforms for the ABI baselines will have end-of-life. The Python community must actively track the end-of-life support and CVEs for different system libraries used by the pr...
Nov 13, 2024 · ABI Tag# The ABI tag indicates which Python ABI is required by any included extension modules. For implementation-specific ABIs, the implementation is abbreviated in the same way as the Python Tag, e.g. cp33d would be the CPython 3.3 ABI with debugging. The CPython stable ABI is abi3 as in the shared library suffix.
Windows. C:\> py -m pip install quux C:\> py -m pip install bar. Prior to v6.1.0, pip made no commitments about install order. The decision to install topologically is based on the principle that installations should proceed in a way that leaves the environment usable at each step. This has two main practical benefits:
NumPy has a C API, which Cython, SciPy, and many other packages use. That ABI is forward but not backward compatible, meaning if you use it then you must build your wheels against the lowest NumPy version that you expect your users to use. So if you build against version 1.X.Y then the runtime requirement you get is numpy>=1.X.Y.
Jul 20, 2024 · Here is an example of how the Python ABI is used in CPython. Consider the following Python code: import math. result = math.sqrt(16.0) This code imports the math module and calls the sqrt() function to calculate the square root of 16.0. The math module is implemented as a C extension module, which is linked dynamically to the Python interpreter.

Feb 9, 2021 · PEP 384 and this document deal with the Limited API and the Stable ABI, two related but distinct concepts. In short: The Stable ABI is a promise that certain extensions compiled with CPython 3.x will be binary compatible with all subsequent versions of CPython 3.x. The Limited API is a subset of CPython’s C API that produces such extensions.
