Question

我尝试通过 python setup.py install 为FANN编译python绑定（pyfann）。安装了Visual Studio 2010和SWIGWIN后，我遇到了几个错误。

在Windows 7和/或8下有没有人为Python 2.7编译python绑定的预编译版本？我也尝试了一个pyfann under windows，但是_libfann.pyd的构建中止了。

Answer 1

我为python 2.7编译了fann 您可以从此处下载：https://github.com/jacekm-git/pyfann_python2.7_windows

编译步骤：

1。 Swig安装：

下载：sourceforge.net/projects/swig/files/swigwin /
将文件解压缩到C：\ swigwin \
编辑系统路径变量
- rigth click MyComputer - ＆gt;特性
- “高级”标签 - ＆gt; “环境变量”
- 编辑“路径”变量 - ＆gt;在行尾添加“; C：\ swigwin \; C：\ python27 \; C：\ python27 \ Scripts \”。

2。 Microsoft Visual C ++ Studio 2008 Express：

下载并安装：go.microsoft.com/?linkid=7729279

3。 Fann 2.1

下载：http://sourceforge.net/projects/fann/files/fann/2.1.0beta/fann-2.1.0beta.zip/download
将文件解压缩到：C：\ fann \

4。编译fanndoubled.dll

在Visual C ++ Studio 2008中打开C：\ fann \ MicrosoftWindowsDll \ windll.vcproj
构建 - ＆gt;建立windll
将文件fanndoubled.dll，fanndoubled.lib复制到C：\ fann \ python \ pyfann

5。痛饮

打开命令提示符


    cd c:\fann\python\pyfann\
    swig -c++ -python pyfann.i

在Visual C ++ Studio 2008 C：\ fann \ python \ pyfann.wrap.cxx中打开
- 查找行（ctrl + f）：SWIGINTERN PyObject * _wrap_training_data_parent_create_train_from_callback



    SWIGINTERN PyObject *_wrap_training_data_parent_create_train_from_callback(PyObject*SWIGUNUSEDPARM(self), PyObject *args) {
      PyObject *resultobj = 0;
      FANN::training_data *arg1 = (FANN::training_data *) 0 ;
      unsigned int arg2 ;
      unsigned int arg3 ;
      unsigned int arg4 ;
      void (*arg5)(unsigned int,unsigned int,unsigned int,fann_type *,fann_type *) = (void (*)(unsigned int,unsigned int,unsigned int,fann_type *,fann_type *)) 0 ;
      // .... rest of file ...

更改为：



    typedef void (__stdcall *arg5_fn)(unsigned int, unsigned int, unsigned int, fann_type*, fann_type*); // added line 
    SWIGINTERN PyObject *_wrap_training_data_parent_create_train_from_callback(PyObject *SWIGUNUSEDPARM(self), PyObject *args) {
      PyObject *resultobj = 0;
      FANN::training_data *arg1 = (FANN::training_data *) 0 ;
      unsigned int arg2 ;
      unsigned int arg3 ;
      unsigned int arg4 ;
      /* void (*arg5)(unsigned int,unsigned int,unsigned int,fann_type *,fann_type *) = (void (*)(unsigned int,unsigned int,unsigned int,fann_type *,fann_type *)) 0 ;*/
      arg5_fn arg5= (arg5_fn)NULL; // added line
      // ....

6。 setup.py

在编辑器C：\ fann \ python \ pyfann \ setup.py
查找和评论专栏：



    # swig_cmd = 'swig -c++ -python pyfann/pyfann.i'
    # print 'Running SWIG before:', swig_cmd
    # os.system(swig_cmd)

将设置行更改为：



    ext_modules=[Extension('pyfann._libfann',['pyfann/pyfann_wrap.cxx'], 
                            include_dirs=['../src/include'], 
                            # extra_objects=['../src/doublefann.o'], 
                            libraries = ['pyfann/fanndoubled'],
                            define_macros=[("SWIG_COMPILE",None)]
                                ),

7。安装



    cd C:\fann\python\
    python setup.py install
    copy C:\fann\python\pyfann\fanndoubled.dll C:\Python27\Lib\site-packages\pyfann\
