Annotell OpenLABEL

Installation

Install the Annotell OpenLABEL package from pip with

pip install annotell-openlabel

Serialization and deserialization

Since all models inherit from pydantic's BaseModel, serialization and deserialization from dicts or json strings are relatively straight forward.

data = {
    "openlabel": {
        "metadata": {
            "schema_version": "1.0.0"
        }
    }
}

import annotell.openlabel.models as OLM

# Deserialize dict
openlabel_annotation = OLM.OpenLabelAnnotation.parse_obj(data)

# Serialize to json
json_data = openlabel_annotation.json(exclude_none=True)

# Deserialize json
openlabel_annotation = OLM.OpenLabelAnnotation.parse_raw(json_data)

# Serialize to dict
dict_data = openlabel_annotation.dict(exclude_none=True)
