后续讲解只会给出代码片段,完整的代码请参见https://github.com/SingleZombie/DL-Demos/tree/master/dldemos/ddpm。git clone 仓库并安装后,可以直接运行目录里的main.py训练模型并采样。 获取数据集 PyTorch的torchvision提供了获取了MNIST的接口,我们只需要用下面的函数就可以生成MNIST的Dataset实例。参数中,root为数...
Azula is a Python package that implements diffusion models in PyTorch. Its goal is to unify the different formalisms and notations of the generative diffusion models literature into a single, convenient and hackable interface. In the Avatar cartoon, Azula is a powerful fire and lightning bender ...

A PyTorch implementation of the paper "ZigMa: A DiT-Style Mamba-based Diffusion Model" - VisionMamba/zigma
This library provides the tools for training and sampling diffusion models in SE(3), implemented in PyTorch. We apply them to learn 6D grasp distributions. We use the learned distribution as cost function for grasp and motion optimization problems. See reference [1] for additional details. ...
