AttributeError: 'DocChunk' object has no attribute 'from_data'

[AdityaMannu1709]

Was running example notebook "advanced_chunking_with_merging.ipynb" but encountered couple of errors......

1. Import Cell -- ImportError: cannot import name 'DocChunk' from 'docling_core.transforms.chunker' as missing in "init.py"

from docling_core.transforms.chunker import (
    BaseChunk,
    BaseChunker,
    DocChunk,
    DocMeta,
    HierarchicalChunker,
)

Fixed by adding below import line -

from docling_core.transforms.chunker.hierarchical_chunker import DocChunk

2. AttributeError: 'DocChunk' object has no attribute 'from_data'

new_chunk = DocChunk.from_data(text=window_text, meta=meta, delim=self.delim)

~\AppData\Local\Programs\Python\Python312\Lib\site-packages\pydantic\_internal\_model_construction.py:320, in ModelMetaclass.__getattr__(self, item)
    318 if private_attributes and item in private_attributes:
    319     return private_attributes[item]
--> 320 raise AttributeError(item)

@AdityaMannu1709 the example "advanced_chunking_with_merging.ipynb" you are referring to is not part of the main branch.
It is still in development and undergoing changes in a separate branch, so it would not be advised to build around it yet.
That said, we expect to have a stable version of these capabilities soon, so stay tuned!
