调研方向
Start with the linked LoboForge-LensTrainer repository, especially train.py, configs/train_lora_lens_base_24gb.yaml, and the Sebastian/Jessica v2 writeup. The issue demonstrates an external config-driven LoRA workflow but does not identify an in-repository change or acceptance criteria, so a maintainer must first decide whether any integration, documentation, or follow-up is wanted.

描述
Hi Lens team,
We've built and validated a standalone LoRA trainer for microsoft/Lens-Base and wanted to share it in case it's useful to the community or future official tooling.
Trainer repo: https://github.com/LoboForge/LoboForge-LensTrainer
Hugging Face Space: https://huggingface.co/spaces/LoboForge/LoboForge-LensTrainer
HF collection: https://huggingface.co/collections/LoboForge/lens-training-loboforge
What works today
- Config-driven training:
python train.py configs/train_lora_lens_base_24gb.yaml - Flow-match loss aligned with
LensPipeline(latents[B, H×W, 128], GPT-OSS multi-layer text,timestep/1000) - PEFT LoRA on
LensTransformer2DModel; TE/VAE frozen - ComfyUI-compatible export (
diffusion_model.*key remap) - 24GB preset: CPU offload, TE + latent cache,
disable_mxfp4, grad checkpointing, AdamW 8-bit - Checkpoint resume, mid-training samples,
loss.json
Example result (community LoRA, not Microsoft-endorsed)
- Writeup: https://github.com/LoboForge/LoboForge-LensTrainer/blob/main/docs/loras/sebastian-jessica-v2.md
- Weights (HF): https://huggingface.co/LoboForge/lens-lora-sebastian-jessica-v2
Environment
- Lens installed from
vendor/Lens(git clone; upstream has nopyproject.toml) - Tested on consumer/datacenter GPUs with Lens-Base local or HF hub
We're not asking for an immediate merge — mainly flagging that Lens-Base LoRA training is practical with the public inference package, and happy to answer questions or share configs/logs if helpful.
Thanks for open-sourcing Lens!
