1. 安装Cython Cython可以通过pip进行安装,只需要在终端中运行如下命令即可: ``` pip install cython ``` 2. 编写扩展模块 Cython和Python代码的文件类型都是.py,因此,我们可以直接在Python文件中编写Cython代码。在Python文件中,我们需要添加如下行来表明这个文件中包含Cython代码: ``` # cython: language_level=...
from Cython.Buildimportcythonize setup( name ='Great Circle module v1', ext_modules = cythonize("great_circle_cy_v1.pyx", compiler_directives={'language_level':"3"} # or"2"or"3str" ), ) 不再报警告。
修改cython的setup.py编译文件内容: AI检测代码解析 from distutils.core import setup from Cython.Build import cythonize setup( name = 'Great Circle module v1', ext_modules = cythonize("great_circle_cy_v1.pyx", compiler_directives={'language_level' : "3"} # or "2" or "3str" ), ) 1...

from Cython.Build import cythonize setup( name = 'Great Circle module v1', ext_modules = cythonize("x2.pyx", #compiler_directives={'language_level' : "3"} # or "2" or "3str" ), ) 1. 2. 3. 4. 5. 6. 7. 8. 9.

cython编译工具存在两个命令行工具cython和cythonize,我们下面会这个示例代码和例子 #cython:language_level=3cdeflistsieveOfEratosthenes(longn):cdeflistpr=[Trueforiinrange(n+1)]cdeflongp=2while(p*p<=n):if(pr[p]==True):foriinrange(p*p,n+1,p):pr[i]=Falsep+=1# end-whilecdeflistres=list(...
其一是普通的.py文件中的Python代码调用Cython代码; 其二是Cython代码,位于.pyx文件中(后缀来自于其起源的项目Pyrex)。Python代码部分如下: importnumpyasnpfromPILimportImageimportpyximport;pyximport.install(language_level=3,setup_args={'include_dirs':np.get_include()})importcyfilterimage=Image.open("../...
Cython编译python为so代码加密⽰例 1. 编译出来的so⽐⽹上流传的其他⽅法⼩很多。2. language_level 是python的主版本号，如果python版本是2.x,⽬前的版本Cython需要⼈⼯指定language_level.3. python setup.py build_ext --inplace 执⾏脚本 4. 以下是代码⽚段 from distutils.core import ...
