Hugging Face 上的指令嵌入

Hugging Face sentence-transformers 是一个用于最先进句子、文本和图像嵌入的 Python 框架。 HuggingFaceInstructEmbeddings 类中使用了指令嵌入模型之一。

from langchain_community.embeddings import HuggingFaceInstructEmbeddings

API Reference:HuggingFaceInstructEmbeddings

embeddings = HuggingFaceInstructEmbeddings(
    query_instruction="Represent the query for retrieval: "
)

load INSTRUCTOR_Transformer
max_seq_length  512

text = "This is a test document."

query_result = embeddings.embed_query(text)
