This is the PyTorch implementation. The MegEngine version is at https://github.com/megvii-model/DiverseBranchBlock
Paper: https://arxiv.org/abs/2103.13425
Will update this whole repo very soon.
Update: released the code for building the block, transformations and verification.
Sometimes I call it ACNet v2 because 'DBB' is two bits larger than 'ACB' in ASCII. (lol)
