以下小节描述了构建扩展模块的几种方法,以及如何将指令传递给Cython编译器。 1. 从命令行编译 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...

3、编写gcn.py。注意添加# cython: language_level=3,不然默认用的是python2: 代码语言:javascript 复制 # cython:language_level=3importtorchimporttorch.nnasnnimporttorch.nn.functionalasFimportdgl from dgl.dataimportCoraGraphDataset from dgl.nnimportGraphConv ...

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 ...
