- class langchain_community.embeddings.anyscale.AnyscaleEmbeddings[source]¶
Bases:
OpenAIEmbeddings
Anyscale 嵌入式 API。
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.

任何规模的端点 API 密钥。
- Constraints
type = string
writeOnly = True
format = password
- param chunk_size: int = 1000¶
每个批次中嵌入的最大文本数量
- param default_headers: Union[Mapping[str, str], None] = None¶
- param default_query: Union[Mapping[str, object], None] = None¶
- param deployment: Optional[str] = 'text-embedding-ada-002'¶
- param disallowed_special: Union[Literal['all'], Set[str], Sequence[str]] = 'all'¶
- param embedding_ctx_length: int = 500¶

- param headers: Any = None¶
- param http_client: Union[Any, None] = None¶
可选的 httpx.Client。
- param max_retries: int = 2¶
生成时最大的重试次数。
- param model: str = 'thenlper/gte-large'¶
要使用的模型名称。
- param model_kwargs: Dict[str, Any] [Optional]¶
保存任何在`create`调用中有效但未明确指定的模型参数。
- param openai_api_base: Optional[str] = None (alias 'base_url')¶
API请求的基本URL路径,如果不使用代理或服务模拟器,请留空。
- param openai_api_key: Optional[str] = None (alias 'api_key')¶
如果未提供,将自动从环境变量`OPENAI_API_KEY`中推断。
- param openai_api_type: Optional[str] = None¶
- param openai_api_version: Optional[str] = None (alias 'api_version')¶
如果未提供,将自动从环境变量`OPENAI_API_VERSION`中推断。
- param openai_organization: Optional[str] = None (alias 'organization')¶
如果未提供,将自环境变量`OPENAI_ORG_ID`自动推断。
- param openai_proxy: Optional[str] = None¶
- param request_timeout: Optional[Union[float, Tuple[float, float], Any]] = None (alias 'timeout')¶
请求到OpenAI完成API的超时时间。可以是浮点数、httpx.Timeout或None。
- param retry_max_seconds: int = 20¶
重试之间等待的最大秒数
- param retry_min_seconds: int = 4¶
重试之间等待的最短秒数
- param show_progress_bar: bool = False¶
在嵌入时是否显示进度条。
- param skip_empty: bool = False¶
是否在嵌入时跳过空字符串或引发错误。 默认情况下不跳过。
- param tiktoken_enabled: bool = False¶
将此设置为False,用于嵌入API的非OpenAI实现。
- param tiktoken_model_name: Optional[str] = None¶
在使用这个类时,传递给tiktoken的模型名称。 Tiktoken用于计算文档中令牌的数量,以限制它们在某个特定限制之下。默认情况下,当设置为None时,这将与嵌入模型名称相同。然而,在一些情况下,您可能希望使用这个嵌入类与tiktoken不支持的模型名称一起使用。这可能包括使用Azure嵌入或使用许多提供类似OpenAI API但具有不同模型的模型提供商之一。在这些情况下,为了避免在调用tiktoken时出错,您可以在这里指定要使用的模型名称。

- 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

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
