__call__()

This operation in JinaEmbeddingFunction takes a list of text strings and directly encodes them into vector embeddings.

The __call__() method of JinaEmbeddingFunction shares the same functionality as encode_documents() and encode_queries().

Request syntax

# Instance created

jina_ef = JinaEmbeddingFunction()

# __call__ method will be called
jina_ef(
    texts: List[str]
) -> List[np.array]

PARAMETERS:

• texts (List[str])

  A list of string values, where each string represents text 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:

• RuntimeError

  This exception will be raised when the response from the Jina API does not contain the data key.

Examples

from pymilvus.model.dense import JinaEmbeddingFunction

jina_ef = JinaEmbeddingFunction(
    model_name="jina-embeddings-v2-base-en", # Defaults to `jina-embeddings-v2-base-en`
    api_key="YOUR_JINAAI_API_KEY" # Provide your Jina AI API key
)
