Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

python

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("sentence_transformers_model_id")
# Run inference
queries = [
    '上学文具分享',
]
documents = [
    '准初三生的书包里有啥😉👉🏻💗\n都是一些很真实的东西哈哈哈 \n我就问有谁懂…？\n#笔袋[话题]# #笔袋介绍[话题]# #我的文具分享[话题]# \n#晒晒我的书桌[话题]# #我的日常[话题]# \n#whatsinmybag[话题]# #书包里面装什么[话题]# \n#书包[话题]# ',

]
query_embeddings = model.encode_query(queries)
document_embeddings = model.encode_document(documents)
print(query_embeddings.shape, document_embeddings.shape)
# [1, 1792] [3, 1792]

# Get the similarity scores for the embeddings
similarities = model.similarity(query_embeddings, document_embeddings)
print(similarities)
# tensor([[ 0.6374,  0.0472, -0.0356]])
