Class ShapeSpec

detectron2/layers/shape_spec.py:6–20

A simple structure that contains basic shape specification about a tensor. It is often used as the auxiliary inputs/outputs of models, to complement the lack of shape inference ability among pytorch modules. Attributes: channels: height: width: strid
