 [FlowVision](https://github.com/Oneflow-Inc/vision) is a tool library matching with OneFlow, specific to computer vision tasks. It contains a number of models, data augmentation methods, data transformation operations and datasets. Here we import and use the data transformation module `transforms` and datasets module `datasets` provided by FlowVision.

-Its specialty is that when Sequential propagates forward, Sequential automatically "concatenates" the layers contained in the container. Specifically, the output of the previous layer will be automatically transferred as the input of the next layer according to the sequence of Sequential added to each layer until the output of the last layer of the whole Moudle is obtained.
