This repository hosts Raster2Seq's PyTorch checkpoints for floorplan reconstruction. Each checkpoint is stored in its own subfolder so users can download all checkpoints or only the subfolder they need.

Available Checkpoints

Checkpoint key	Dataset	RoomF1	Subfolder
s3d-bw	Structured3D-B	99.6	s3d-bw/
cubicasa5k	CubiCasa5K	88.7	cubicasa5k/
raster2graph	Raster2Graph	97.0	raster2graph/
raster2graph-512	Raster2Graph-512	98.1	Raster2Graph-512/
s3d-density	Structured3D-DensityMap	99.1	s3d-density/

Download All Checkpoints

from huggingface_hub import snapshot_download

local_repo = snapshot_download(repo_id="haopt/Raster2Seq")

Download One Checkpoint Subfolder

from huggingface_hub import snapshot_download

local_repo = snapshot_download(
    repo_id="haopt/Raster2Seq",
    allow_patterns="Raster2Graph-512/*",
)

Raster2Seq Helper

With the Raster2Seq codebase, users can load by alias:

python eval.py --checkpoint hf:cubicasa5k ...

or download directly:

from raster2seq_hub import download_checkpoint

ckpt_path = download_checkpoint("cubicasa5k")
