Hello! I've read your paper: 'Directed Diffusion: Direct Control of Object Placement through Attention Guidance'. I saw your method is to optim a learned weight vector 'a'∈ R_77−|P|−1. I'm interested about it , but I didn't find where it implemented in your code. I would like to know if you can provide your full code support. My email is mycf2286247133@gmail.com. Thanks a lot!
