I found the problem. tensorflow.python.keras.layers .UpSampling2D , just like this:

 node {
      name: "up_sampling2d_3/mul"
        op: "Mul"
        input: "up_sampling2d_3/strided_slice"
       input: "up_sampling2d_3/Const"
     }

the op "Mul" assert "scaleMat.type() == CV_32FC1", when i removed the Upsample2D layer, it works.But now, i do not know how to fix it.
