Models Definition module

The basic network (supernet) is defined by the unified framework with the structure info list. CnnNet is the overall backbone network, which is composed of differet downsample stages with structure info list. A stage is composed of several blocks, such as Resnet bottleneck block, MobileV2 Depthwise block. Basic block is composed of 2D convolutions.

SuperModel

  • cnnnet.py: Define the backbone network for CnnNet, such as classification and detection.
