.EmbaasEmbeddings¶
- class langchain_community.embeddings.embaas.EmbaasEmbeddings[source]¶
Bases:
BaseModel
,Embeddings
Embaas的嵌入式服务。
要使用,您应该设置环境变量``EMBAAS_API_KEY``并使用您的API密钥,或将其作为构造函数的命名参数传递。
- 示例:
# 使用默认模型和指令进行初始化 from langchain_community.embeddings import EmbaasEmbeddings emb = EmbaasEmbeddings() # 使用自定义模型和指令进行初始化 from langchain_community.embeddings import EmbaasEmbeddings emb_model = "instructor-large" emb_inst = "代表用于检索的维基百科文档" emb = EmbaasEmbeddings( model=emb_model, instruction=emb_inst )
Create a new model by parsing and validating input data from keyword arguments.
Raises ValidationError if the input data cannot be parsed to form a valid model.
- param api_url: str = 'https://api.embaas.io/v1/embeddings/'¶
embaas嵌入式API的URL。
- param embaas_api_key: Optional[pydantic.types.SecretStr] = None¶
请求的最大重试次数
- Constraints
type = string
writeOnly = True
format = password
- param instruction: Optional[str] = None¶
用于领域特定嵌入的指令。
- param max_retries: Optional[int] = 3¶
请求超时时间(秒)
- param model: str = 'e5-large-v2'¶
用于嵌入的模型。
- param timeout: Optional[int] = 30¶
- async aembed_documents(texts: List[str]) List[List[float]] ¶
Asynchronous 嵌入搜索文档。
- Parameters
texts (List[str]) –
- Return type
List[List[float]]
- async aembed_query(text: str) List[float] ¶
Asynchronous 嵌入查询文本。
- Parameters
text (str) –

List[float]
- classmethod construct(_fields_set: Optional[SetStr] = None, **values: Any) Model ¶
Creates a new model setting __dict__ and __fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed. Behaves as if Config.extra = ‘allow’ was set since it adds all passed values
- Parameters
_fields_set (Optional[SetStr]) –
values (Any) –
- Return type
Model
- copy(*, include: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, exclude: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, update: Optional[DictStrAny] = None, deep: bool = False) Model ¶
Duplicate a model, optionally choose which fields to include, exclude and change.
- Parameters
include (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) – fields to include in new model
exclude (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) – fields to exclude from new model, as with values this takes precedence over include
update (Optional[DictStrAny]) – values to change/add in the new model. Note: the data is not validated before creating the new model: you should trust this data
deep (bool) – set to True to make a deep copy of the model
self (Model) –
- Returns
new model instance
- Return type
Model
