   @Hzfengsy in the example below:
   
   ```python
   buf = tir.decl_buffer((1,), name='buf')
   ```
   
   which actually indicates:
   
   ```python
   buf = tir.decl_buffer(data=None, shape=(1,), name='buf')
   ```
   
   I suppose it won't happen in our common workflow, but is an adversarial case 
when using our APIs in an arbitrary way
