InstructEmbeddings

让我们加载HuggingFace的InstructEmbeddings类。

from langchain.embeddings import HuggingFaceInstructEmbeddings

embeddings = HuggingFaceInstructEmbeddings(
    query_instruction="表示用于检索的查询："
)

    load INSTRUCTOR_Transformer
    max_seq_length  512

text = "这是一个测试文档。"

query_result = embeddings.embed_query(text)
