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.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("sentence_transformers_model_id")
# Run inference
queries = [
    '保存搜索结果到缓存',
]
documents = [
    'private saveToCache(keyword: string, author: string | undefined, results: NovelSearchResult[], sourceResults: SourceSearchResult[]): void {\n    const cacheKey = this.getCacheKey(keyword, author);\n    const cache: SearchResultCache = {\n      keyword: keyword,\n      author: author,\n      timestamp: Date.now(),\n      results: results,\n      sourceResults: sourceResults\n    };\n    this.searchCache.set(cacheKey, cache);\n    logger.info(TAG, `保存搜索缓存: ${keyword}, ${sourceResults.length}个书源, ${results.length}本书`);\n  }',
    'public get isConnected(): boolean {\n    return this.client?.isConnected() ?? false;\n  }',
    'constructor(networkDataSource?: AuthNetworkDataSource) {\n    this.networkDataSource = networkDataSource ?? new AuthNetworkDataSourceImpl();\n  }',
]
query_embeddings = model.encode_query(queries)
document_embeddings = model.encode_document(documents)
print(query_embeddings.shape, document_embeddings.shape)
# [1, 1024] [3, 1024]

# Get the similarity scores for the embeddings
similarities = model.similarity(query_embeddings, document_embeddings)
print(similarities)
# tensor([[ 0.7422, -0.1270, -0.0065]], dtype=torch.bfloat16)
