encode_documents()

This operation takes in documents and encodes them into vector embeddings.

Request syntax

encode_documents(
    documents: List[str], 
) -> List[np.array]

PARAMETERS:

  • documents (List[str])

    A list of string values, where each string represents a document that will be passed to the embedding model for encoding. The model will generate an embedding vector for each string in the list.

RETURN TYPE:

List[np.array]

RETURNS:

A list where each element is a NumPy array.

Exceptions:

  • ImportError

    This exception will be raised when the OpenAI module is not installed.

Examples

from pymilvus import model

openai_ef = model.dense.OpenAIEmbeddingFunction(
    model_name='text-embedding-3-large', # Specify the model name
    dimensions=512 # Set the embedding dimensionality according to MRL feature.
)
