一个很简单的例子，使用c#调用tensorflow。

1.安装tensorflow

首先需要安装windows 版本的tensowflow，使用64位的python3.5，如果没有安装，需要首先安装python3.5

然后以管理员方式进入命令行，运行

pip install tensorflow

 2.c#调用代码

初始化cle和python35

      StarCoreFactory starcore = StarCoreFactory.GetFactory();

      StarServiceClass Service = starcore._InitSimple("test", "123", 0, 0, null);

      StarSrvGroupClass SrvGroup = (StarSrvGroupClass)Service._Get("_ServiceGroup");

      //--init python raw interface

      SrvGroup._InitRaw("python35", Service);

      StarObjectClass python = Service._ImportRawContext("python", "", false, "");

 调用tensorflow

     //--import tensorflow as tf

     python._Call("eval", "import tensorflow as tf");   

     StarObjectClass tf = python._GetObject("tf");

     Console.WriteLine(tf);

     //-- a = tf.add(2,5)

     StarObjectClass a = (StarObjectClass)tf._Call("add", 2, 5);

     //-- b = tf.multiply(a,5)

     StarObjectClass b = (StarObjectClass)tf._Call("multiply", a, 3);

     //-- c = tf.constant(2,name="Node_c")

     StarObjectClass c = (StarObjectClass)tf._Call("constant", 2, SrvGroup._NewParaPkg("name", "Node_c")._AsDict(true));

     Console.WriteLine(c);

     //-- sess = tf.Session()

     StarObjectClass Session = (StarObjectClass)tf._Get("Session");

     StarObjectClass sess = Session._New();

     //-- result = sess.run(b,feed_dict={a:25});

     StarParaPkgClass pkg = SrvGroup._NewParaPkg(a, 25)._AsDict(true);

     Object result = sess._Call("run", b, SrvGroup._NewParaPkg("feed_dict", pkg)._AsDict(true));

     Console.WriteLine(result);

如果使用dynamic关键字，上述代码简化如下：

     //--import tensorflow as tf

     python.eval("import tensorflow as tf");

     dynamic tf = python.tf;

     //-- a = tf.add(2,5)

     dynamic a = tf.add(2, 5);

     //-- b = tf.multiply(a,5)

     dynamic b = tf.multiply(a, 3);

     //-- c = tf.constant(2,name="Node_c")

     dynamic c = tf.constant(2, SrvGroup._NewParaPkg("name", "Node_c")._AsDict(true));

     //-- sess = tf.Session()

     dynamic Session = tf.Session;

     dynamic sess = Session._New();

     //-- result = sess.run(b,feed_dict={a:25});

     var pkg = SrvGroup._NewParaPkg(a, 25)._AsDict(true);

     dynamic result = sess.run(b, SrvGroup._NewParaPkg("feed_dict", pkg)._AsDict(true));

     Console.WriteLine(result);
