model2vec
概览
Model2Vec 是一种将任何句子转换器转化为非常小的静态模型的技术。 model2vec 可用于生成嵌入表示。
设置
pip install -U langchain-community
Instantiation
确保已安装 model2vec
pip install -U model2vec
索引与检索
from langchain_community.embeddings import Model2vecEmbeddings
API 参考:Model2vec嵌入
embeddings = Model2vecEmbeddings("minishlab/potion-base-8M")
query_text = "This is a test query."
query_result = embeddings.embed_query(query_text)
document_text = "This is a test document."
document_result = embeddings.embed_documents([document_text])
直接使用
您可以直接使用 model2vec 的方式如下
from model2vec import StaticModel
# Load a model from the HuggingFace hub (in this case the potion-base-8M model)
model = StaticModel.from_pretrained("minishlab/potion-base-8M")
# Make embeddings
embeddings = model.encode(["It's dangerous to go alone!", "It's a secret to everybody."])
# Make sequences of token embeddings
token_embeddings = model.encode_as_sequence(["It's dangerous to go alone!", "It's a secret to everybody."])
