Question

当我有形状[2,2,2]的数据时，例如：

a = np.array([[(1,2), (3,4)],
              [(5,6), (7,8)]
              ])

我希望图层输出[2,2]，例如：

b = np.array([[1,0],
              [0,1]])

如何构建图层？我当前的设置返回[2,2,1]的形状，我似乎无法在图层的单位变量中指定尺寸：

tf_x = tf.placeholder(tf.float32, [None, 2, 2]) 

output = tf.layers.dense(tf_x, 1, tf.nn.relu) 

with tf.Session() as sess:
    sess.run(tf.global_variables_initializer())    
    pred = sess.run(output, {tf_x: a})

Answer 1

您可以这样做：

b = tf.reshape(a, shape)

Answer 2

我当前的设置返回[2,2,1]的形状，我似乎无法在图层的单位变量中指定尺寸：

#include<windows.h>
#include <GL/glut.h>
float yRot=0.0;
void Render()
{
  //clear color and depth buffer
  glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
  glLoadIdentity();//load identity matrix

  glTranslatef(0.0f,0.0f,-4.0f);//move forward 4 units

  //rotate along the y-axis
  glRotatef(yRot,0.0f,1.0f,0.0f);

  glColor3f(0.0f,0.0f,1.0f); //blue color

  glBegin(GL_POLYGON);//begin drawing of polygon
    glVertex3f(-0.5f,0.5f,0.0f);//first vertex
    glVertex3f(0.5f,0.5f,0.0f);//second vertex
    glVertex3f(1.0f,0.0f,0.0f);//third vertex
    glVertex3f(0.5f,-0.5f,0.0f);//fourth vertex
    glVertex3f(-0.5f,-0.5f,0.0f);//fifth vertex
    glVertex3f(-1.0f,0.0f,0.0f);//sixth vertex
  glEnd();//end drawing of polygon

  yRot+=0.1f;//increment the yRot variable
}
//method the reshape the entire figure.
void reshape(int x, int h){
    glViewport(0,0,x,h);
}
void init()
{
    glClearColor(0.0,0.0,0.2,0.8);
}
int main(int argc, char** argv)
{
   glutCreateWindow("simple triangles");
   glutDisplayFunc(Render);
   glutReshapeFunc(reshape);
   init();

   glutMainLoop();
}

如何在张量流中形成重塑层？
