我正在使用Model Builder训练值预测模型，但预测值始终为0

Question

训练完使用评估界面进行预测可以得到正常的预测值，但我将使用中的范例代码加入我的项目后，再次预测得到的结果始终为0，这是为什么?

我的代码如下:

public void button1_Click(object sender, EventArgs e)

{

//Load sample data

var sampleData = new TP2TP3_3T_Final_TXP.ModelInput()

{

    TXP = 0.92F,

    Outer_ER = 6.44F,

    Outer_OMA = 1.92F,

    TDECQ = 1.75F,

    RLM = 0.959F,

    Ceq = 0.77F,

    TDECQ_Ceq = 0.98F,

    Level0 = 491F,

    Level1 = 976F,

    Level2 = 1461F,

    Level3 = 2008F,

    MPDA_Setpoint = 280F,

    DMPD_Setpoint = 567F,

    MPDA_Setpoint_Final = 301F,

    DMPD_Setpoint_Final = 721F,

};

//Load model and predict output

var result = TP2TP3_3T_Final_TXP.Predict(sampleData);

textBox1.Text = result.TXP_Final.ToString();

}
