🆕 Features

More serialization options for DocVec (#1562)

DocVec now has the same serialization interface as DocList. This means that that following methods are available for it:

• to_protobuf()/from_protobuf()
• to_base64()/from_base64()
• save_binary()/load_binary()
• to_bytes()/from_bytes()
• to_dataframe()/from_dataframe()

For example, you can now perform Base64 (de)serialization like this:

from docarray import BaseDoc, DocVec

class SimpleDoc(BaseDoc):
    text: str

dv = DocVec[SimpleDoc]([SimpleDoc(text=f'doc {i}') for i in range(2)])
base64_repr_dv = dv.to_base64(compress=None, protocol='pickle')

dl_from_base64 = DocVec[SimpleDoc].from_base64(
    base64_repr_dv, compress=None, protocol='pickle'
)

For further guidance, check out the documentation section on serialization.

Validate file formats in URL (#1606) (#1669)

Validate the file formats given in URL types such as AudioURL, TextURL, ImageURL to check they correspond to the expected mime type.

Add methods to create BaseDoc from schema (#1667)

Sometimes it can be useful to dynamically create a BaseDoc from a given schema of an original BaseDoc. Using the methods create_pure_python_type_model and create_base_doc_from_schema you can make sure to reconstruct the BaseDoc.

from docarray.utils.create_dynamic_doc_class import (
    create_base_doc_from_schema,
    create_pure_python_type_model,
)

from typing import Optional
from docarray import BaseDoc, DocList
from docarray.typing import AnyTensor
from docarray.documents import TextDoc

class MyDoc(BaseDoc):
    tensor: Optional[AnyTensor]
    texts: DocList[TextDoc]

MyDocPurePython = create_pure_python_type_model(MyDoc) # Due to limitation of DocList as Pydantic List, we need to have the MyDoc `DocList` converted to `List`.
NewMyDoc = create_base_doc_from_schema(
    MyDocPurePython.schema(), 'MyDoc', {}
)

new_doc = NewMyDoc(tensor=None, texts=[TextDoc(text='text')])

🐞 Bug Fixes

Cap Pydantic version (#1682)

Due to the breaking change in Pydantic v2, we have capped the version to avoid problems when installing DocArray.

Better error message when DocVec is unusable (#1675)

After calling doc_list = doc_vec.to_doc_list(), doc_vec ends up in an unusable state since its data has been transferred to doc_list. This fix gives users a more informative error message when they try to interact with doc_vec after it has been made unusable.

📗 Documentation Improvements

• Fix a reference in README (#1674)
