Repo: purediffusion

I created a repo, purediffusion.
It is also available through pip:

pip install purediffusion

purediffusion is a torch implementation I used for DDPM with DDIM sampling. This implementation is not restricted for Image data. It is a convinient start to build a diffusion model for arbitrary data type. One can just design the network structure and data format, without coping with the coefficients in the diffusion schedule and the generation process.
