依赖项
要使用 LangChain 中的 LaserEmbed，安装 laser_encoders Python 包。
%pip install laser_encoders
导入
from langchain_community.embeddings.laser import LaserEmbeddings
API 参考：LaserEmbeddings
实例化激光
参数
lang: Optional[str]If empty will default to using a multilingual LASER encoder model (called "laser2"). You can find the list of supported languages and lang_codes here and here .
# Ex Instantiationz
embeddings = LaserEmbeddings(lang="eng_Latn")
使用
生成文档嵌入
document_embeddings = embeddings.embed_documents(
["This is a sentence", "This is some other sentence"]
)
生成查询嵌入
query_embeddings = embeddings.embed_query("This is a query")
