模型保存代码:

def save_model(path):
    if not os.path.exists(path):
        os.makedirs(path)
    print ('save models to %s' % (path))
    fluid.io.save_inference_model(path,   #保存推理model的路径
                                      ['team_a', 'team_b'],     #推理（inference）需要 feed 的数据
                                      [predict],                #保存推理（inference）结果的 Variables
                                      exe,                      #executor 保存 inference model
                                      train_prog)

    print('训练模型保存完成！')
