## Overview

This repository hosts fine-tuned **Stage 1 (PGF)** checkpoints across multiple training paradigms:
1. **`from_text_baseline/`**: Trained directly from the `pgf_text` checkpoint on realistic images without prior synthetic image cross-attention.
2. **`pgf_image_realistic_step*/`**: Fine-tuned from the pretrained `pgf_image` baseline.
3. **`edge/`**: Pretrained Stage 2 Edge Model for 2D sewing pattern reconstruction.
4. **`test_images/`**: 200 evaluation garment test images (`eval_set_40_prompt5`).

## Quickstart & Inference

Download a specific checkpoint:

```bash
# Example: Download step 1000 from from_text_baseline along with edge model and test images
hf download image2garment/GarmentParticles-Realistic   --include "from_text_baseline/pgf_image_realistic_step1000/*" "edge/*" "test_images/*"   --local-dir checkpoints_hub/realistic
```

Run two-stage image-conditioned inference:

```bash
torchrun --standalone --nproc_per_node=1 inference/infer_twostage.py \
  eval.sample_per_batch=1 eval.n_samples=0 eval.evaluate=False \
  train.exp_name=realistic_img_samples sample.num_sampling_steps=100 \
  gpf_ckpt=null \
  dataset.front_only=True dataset.use_all_captions=True \
  dataset.img_drop_prob=0 dataset.text_drop_prob=1 \
  model.use_qknorm=True model.use_rope=False model.in_channels=6 model.freeze_everything=False \
  edge_model.use_qknorm=True \
  edge_model_ckpt=checkpoints_hub/realistic/edge \
  model=sparse_lightningdit_v3_xl1_w_img_text_v2 \
  pgf_weight_init=checkpoints_hub/realistic/from_text_baseline/pgf_image_realistic_step1000 \
  --config-name sparselightningdit_xl_garment_particle_inference
