__call__()

OpenAIEmbeddingFunction 中的此操作会接收一个文本字符串列表，并将其直接编码为向量嵌入。

OpenAIEmbeddingFunction 的 __call__() 方法与 encode_documents() 和 encode_queries() 具有相同的功能。

请求语法

python

# Instance created
openai_ef = OpenAIEmbeddingFunction()

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

参数：

• texts (List[str])

  字符串值列表，其中每个字符串都表示将传递给嵌入模型进行编码的文本。模型会为列表中的每个字符串生成一个嵌入向量。

返回类型：

List[np.array]

返回值：

一个列表，其中每个元素都是一个 NumPy 数组。

异常：

• ImportError

  当未安装 OpenAI 模块时，将引发此异常。

示例

python

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.
)
