c#调用tensorflow的例子

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);
