> It is important for any AI platform to have the type inference for each stage and pipeline. We can have some help here for ML pipeline to support such kind of type inference (static type and compatibility check) for each stage and pipeline. 
>  
> That is, each stage shall declare which kind of input type and shape it can accept and it will output. Then, the framework will perform compatibility check to see whether they are compatible or not.
