kohakugbc-data
The data side of KohakuGBC (Graph-Based Captioning), without the captioning machine: GBC graphs (store, resolution, prompt rendering) and the GBC dataset format. Depends on numpy, pillow, pyarrow and kohakuvault only; one wheel per platform for CPython 3.11+.
pip install kohakugbc-data
Graphs
from kohakugbc_data import GbcGraph
g = GbcGraph.from_json(line) # one GBC graph (ml-gbc JSON), or from_msgpack
blob = g.to_msgpack() # typed msgpack + zstd: ~7.6x smaller than JSON
g = GbcGraph.from_msgpack(blob)
text = g.prompt(width=1024, height=1024) # the GBC prompt text (boxes in MOSS layout space)
GbcGraph.prompt / prompt_dag render natively; kohakugbc_data.prompt holds the Python
renderers (from_gbc, render, parse, to_moss for the MOSS-Image layout draft, detail
levels in kohakugbc_data.prompt.detail), equal to the native ones.
Datasets
A GBC dataset: images, graphs and a metadata dict per image, joined by a sample key, in self-contained shards.
<root>/dataset.json format, version, the shard list, the dataset header
<root>/shards/shard_XXXXX/
images.zip KohakuClip image shard: stored zip + __index__.bin
graphs.db KohakuVault "graphs": key -> GbcGraph msgpack (zstd)
meta.db KohakuVault "meta": key -> dict (any content)
manifest.parquet key, index, w, h, codec, sizes, extra columns
from kohakugbc_data.dataset import DatasetWriter, GbcDataset, read_info, split
ds = GbcDataset(root, image="pil") # or "bytes" / None; graphs=, meta=, shards=
s = ds[0] # or ds["<key>"]: key, w, h, codec, image, graph, meta
ds = GbcDataset(root, transform=lambda s: (s.image, s.graph.prompt(width=s.w, height=s.h)))
with DatasetWriter(out, shard_bytes=4 << 30, header={"name": "my-set"}) as w:
w.add(key, image_bytes, width, height, "webp", graph_line, {"tags": tags})
images.zip is byte-identical to what KohakuClip writes for the same images, so
kohakuclip.ImageReader reads it directly. Shards close at shard_bytes and / or
per_shard; distributed jobs take whole shards (split(names, rank, world)). The full format:
