Research direction

Start with examples/flux2/model_training/special/dmd2/FLUX.2-klein-base-4B-DMD2.sh and reproduce the one-epoch run on the reported 8×80 GB H100 setup. Inspect the training configuration and memory behavior to determine the required compute resources; done means providing a supported resource estimate or identifying a reproducible out-of-memory problem.

Description

尝试用1*8 80G H100 运行最近更新的 https://github.com/modelscope/DiffSynth-Studio/blob/main/examples/flux2/model_training/special/dmd2/FLUX.2-klein-base-4B-DMD2.sh 代码，训练一个epoch就oom。想请教下大概需要多少计算资源呢？
