Thanks to the development of the community over the past few months, I quickly learned that Dreambooth was a great algorithm (or model) for training faces. I started with https://github.com/TheLastBen/fast-stable-diffusion, the first available library I found on GitHub, but my graphics card was too small and could only train and run on Colab. As expected, it failed miserably, and I wasn't sure why. Now it seems that the captions I wrote were too poor (I'm not very good at English, and I used ChatGPT to write this post), and I didn't know what to upload for the regularized image.

Dreambooth-Stable-Diffusion
Implementation of Dreambooth (https://arxiv.org/abs/2208.12242) by way of Textual Inversion (https://arxiv.org/abs/2208.01618) for Stable Diffusion (https://arxiv.org/abs/2112.10752). Tweaks focused on training faces, objects, and styles. (by JoePenna)
I quickly turned to the second library, https://github.com/JoePenna/Dreambooth-Stable-Diffusion, because its readme was very encouraging, and its results were the best. Unfortunately, to use it on Colab, you need to sign up for Colab Pro to use advanced GPUs (at least 24GB of VRAM), and training a model requires at least 14 compute units. As a poor Chinese person, I could only buy Colab Pro from a proxy. The results from JoePenna/Dreambooth-Stable-Diffusion were fantastic, and the preparation was straightforward, requiring only <=20 512*512 photos without writing captions. I used it to create many beautiful photos.

Then I started thinking, was there a better way? So I searched on Google for a long time, read many posts, and learned that only text reversal, Dreambooth, and EveryDream had good results on real people, but Lora didn't work. Then I tried Dreambooth again, but it was always a disaster, always! I followed the instructions carefully, but it just didn't work for me, so I had to give up. Then I turned to EveryDream2.0 https://github.com/victorchall/EveryDream2trainer, which actually worked reasonably well, but...there was a high probability of showing my front teeth with an open mouth.
