基于 sentence-transformers/all-MiniLM-L6-v2 的 SentenceTransformer

这是一个基于 sentence-transformers/all-MiniLM-L6-v2 微调的 sentence-transformers 模型。它将句子和段落映射到 384 维的稠密向量空间,可用于语义文本相似度、语义搜索、复述挖掘、文本分类、聚类等任务。

使用方法

直接使用(Sentence Transformers)

首先安装 Sentence Transformers 库:

pip install -U sentence-transformers

然后您可以加载此模型并运行推理。

from sentence_transformers import SentenceTransformer

# 从 🤗 Hub 下载
model = SentenceTransformer("sentence_transformers_model_id")
# 运行推理
sentences = [
    'The weather is lovely today.',
    "It's so sunny outside!",
    'He drove to the stadium.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 384]

# 获取嵌入的相似度分数
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
