swig错误c++；供python控制器使用 当构建工具：CRFSuff时，在构建Python模块时，从C++中的代码> SWIG/中出错： swig -c++ -python -I../../include -o export_wrap.cpp export.i

尝试将

%include“crfsuite\u api.hpp”

移动到第一行

%模板之前
 宾果！我想知道细节，为什么在之前使用注释“#”。
%module(directors="1") crfsuite
%{
#include "crfsuite_api.hpp"
%}

%include "std_string.i"
%include "std_vector.i"
%include "exception.i"

%template(Item) std::vector<CRFSuite::Attribute>;
%template(ItemSequence) std::vector<CRFSuite::Item>;
%template(StringList) std::vector<std::string>;

%feature("director") Trainer;

%exception {
    try {
        $action
    } catch(const std::invalid_argument& e) {
        SWIG_exception(SWIG_IOError, e.what());
    } catch(const std::runtime_error& e) {
        SWIG_exception(SWIG_RuntimeError, e.what());
    } catch (const std::exception& e) {
        SWIG_exception(SWIG_RuntimeError, e.what());
    } catch(...) {
        SWIG_exception(SWIG_RuntimeError,"Unknown exception");
    }
}

%include "crfsuite_api.hpp"
