When creating an empty HnswDocumentIndex, if there were no files indexed (.index called) then the next time the object is instantiated with the same work_dir it will fail.
Python version: 3.11.2
Docarray version: 0.30.0
Reproducible Example:
from docarray import BaseDoc
from docarray.typing import NdArray
from docarray.index import HnswDocumentIndex
class Text(BaseDoc):
embedding: NdArray[128]
text: str
index = HnswDocumentIndex[Text](work_dir="./index")Output:
Traceback (most recent call last):
