   3. 根据token产生模型结构(token2arch函数)，根据搜索到的tokens列表产生模型结构。
      
 
      以新增reset block为例说明如何构造自己的search space。自定义的search space不能和已有的search space同名。

    注意事项
    
 
    在添加蒸馏loss时会引入新的variable，需要注意新引入的variable不要与student variables命名冲突。这里建议两种用法：
    
 
      
 
    1. 建议与student_program使用同一个命名空间，以避免一些未指定名称的variables(例如tmp_0, tmp_1...)多次定义为同一名称出现命名冲突
      2. 
 
    2. 建议在添加蒸馏loss时指定一个命名空间前缀，具体用法请参考Paddle官方文档fluid.name_scope
      3.
