比如过滤、索引、10 分钟内导入 10 亿数据、数据删除更新、多副本、资源隔离、易用的查询能力 (Restful,Python,SQL) 数据备份、监控、报警、流控、API & SDK、是否支持分布式横向扩展以满足大规模数据的查询和存储等等,这些场景该需要如何解决?以上便是向量数据库需要做的。 向量数据库让大模型有了"记忆"的功能,在...

cd ~/ann-benchmarks/ python install.py --algorithm pgvector 说明 您可以执行python install.py --help查看支持配置参数。 步骤四:获取数据集 执行测试脚本时,将自动下载指定的公开测试数据集。 本文以文本相似性检索为例,采用Angular距离类型的数据集nytimes-256-angular进行测试。更多公开的数据集请参见ann-ben...
在本文中,我们将演示如何在应用程序中使用 RAG 技术。为此,我们将使用 Langchain 为 LLM 框架创建一个Flutter应用程序,并使用 pgVector(一个用于向量相似性搜索的开源 Postgres 扩展)创建应用程序。 借助数据库,尤其是那些支持向量功能的数据库,如 Neon,我们可以使用 RAG 技术来帮助 LLM 向最终用户提供准确的答案。...

What if I want to index vectors with more than 2,000 dimensions? You’ll need to usedimensionality reductionat the moment. Can I store vectors with different dimensions in the same column? You can usevectoras the type (instead ofvector(3)). ...
postgresql Fastapi和pgvector：InvalidRequestError：未知PG数字类型将模型中vector列的定义更改为：
For example, use asyncpg in python. Records are sent to the remote index in batches. Therefore pgvector-remote performs a local scan of the unflushed records before every query. To disable this set pinecone.max_buffer_scan to 0. For example,...
