…cript It has not worked since the refactoring removed `train_util.load_tokenizer` (the only thing it needed to run again), and gen_img.py supports everything it did except the experimental CLIP / VGG16 guidance. No user has reported the breakage, so rather than keeping 4,000 lines of duplicated code alive, remove it. The file remains available in the previous releases. The remaining references in the docs (train_network_README-ja / -zh and train_ti_README-ja) now point to gen_img.py. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Summary
Removes
gen_img_diffusers.py, the old image generation script for SD1.x / SD2.x, and points the remaining doc references togen_img.py.train_util.load_tokenizer(it fails withAttributeErrorright after loading the models). This was found while checking the sampler fixes of Fix the dpmsolver / dpmsingle samplers and give a clear error for lms without scipy #2438.dpmsolverfix of Fix the dpmsolver / dpmsingle samplers and give a clear error for lms without scipy #2438), and with that patch applied txt2img, LoRA, SD2 v-prediction and Textual Inversion were confirmed to work locally. But no user has reported the breakage,gen_img.pysupports everything it did except the experimental CLIP / VGG16 guidance (--clip_guidance_scale,--clip_image_guidance_scale,--vgg16_guidance_scale,--vgg16_guidance_layer), and keeping 4,000 lines of duplicated code alive would only add maintenance cost. The file remains available in the previous releases.Changes
gen_img_diffusers.py.docs/train_network_README-ja.md,docs/train_network_README-zh.md,docs/train_ti_README-ja.md: the "generate with the script in this repository" sections now refer togen_img.py(and link togen_img_README). The English docs already did.library/sampling.py: a comment referring to the old script.🤖 Generated with Claude Code
