linux下Cython安装

Project description

The Cython language makes writing C extensions for the Python language as easy as Python itself. Cython is a source code translator based on Pyrex, but supports more cutting edge functionality and optimizations.

The Cython language is a superset of the Python language (almost all Python code is also valid Cython code), but Cython additionally supports optional static typing to natively call C functions, operate with C++ classes and declare fast C types on variables and class attributes. This allows the compiler to generate very efficient C code from Cython code.

This makes Cython the ideal language for writing glue code for external C/C++ libraries, and for fast C modules that speed up the execution of Python code.

Note that for one-time builds, e.g. for CI/testing, on platforms that are not covered by one of the wheel packages provided on PyPI, it is substantially faster than a full source build to install an uncompiled (slower) version of Cython with:

pip install Cython --install-option="--no-cython-compile"

有可能最新的cython版本和你的pip 不对应，这个时候要么升级pip"pip install --upgrade pip",或者安装对应的Cython版本。
