# LSUN Bedroom 256x256 (LMDB) for DiffAE

This dataset repo hosts the LSUN Bedroom **train** split packaged as a single LMDB
(`bedroom256.lmdb`) compatible with DiffAE’s legacy LMDB reader and the new
HF-backed `bedroom_hf` wrapper.

**What’s inside**
- `bedroom256.lmdb/data.mdb`
- `bedroom256.lmdb/lock.mdb`

**Format**
- Keys: `256-0000000`, `256-0000001`, ... (7-digit zero-padded index)
- Values: RGB images encoded as WebP (quality ~90), resized to 256x256
- Total images: **3,033,042**
- Size: ~**49.1 GB** for `data.mdb` (plus small `lock.mdb`)

**How to download (raw LMDB)**
```python
from huggingface_hub import hf_hub_download

repo_id = "konpat/lsun-bedroom-256-lmdb"

data_path = hf_hub_download(
repo_id=repo_id,
repo_type="dataset",
filename="bedroom256.lmdb/data.mdb",
local_dir="./hf_lmdb",
)
lock_path = hf_hub_download(

**How to use in DiffAE**
In a YAML config:
```yaml
data:
name: bedroom_hf
hf:
bedroom_repo_id: konpat/lsun-bedroom-256-lmdb
