- Fixed a bug that the value of timestep embedding during SDXL training was incorrect.
- Please update for SDXL training.
- The inference with the generation script is also fixed.
- The impact is unknown, but please update for SDXL training.
- This fix appears to resolve an issue where unintended artifacts occurred in trained models under certain conditions.
We would like to express our deep gratitude to Mark Saint (cacoe) from leonardo.ai, for reporting the issue and cooperating with the verification, and to gcem156 for the advice provided in identifying the part of the code that needed to be fixed.
