RETURN TYPE:

np.ndarray

RETURNS:

A flattened NumPy array containing all vector embeddings concatenated.

EXCEPTIONS:

• ValueError:

  This exception will be raised if the current EmbeddingList instance is empty.

Examples

from pymilvus import EmbeddingList

# create an empty embedding list
embeddingList = EmbeddingList()

# add multiple vector embeddings in a batch
embeddingList.add_batch(
    embeddings=[[0.1, 0.2, 0.3, 0.4, 0.5], [0.5, 0.4, 0.3, 0.2, 0.1]]
)
