sentence-transformers/msmarco-distilbert-base-dot-prod-v3

这是一个 sentence-transformers 模型：它将句子和段落映射到一个768维的稠密向量空间，可用于聚类或语义搜索等任务。

用法（Sentence-Transformers）

当你安装了 sentence-transformers 时，使用该模型变得很容易:

pip install -U sentence-transformers

然后你可以这样使用模型：

from sentence_transformers import SentenceTransformer
sentences = ["This is an example sentence", "Each sentence is converted"]

model = SentenceTransformer('sentence-transformers/msmarco-distilbert-base-dot-prod-v3')
embeddings = model.encode(sentences)
print(embeddings)
