How can I fetch all the vectors of a namespace in pinecone, as the fetch method expects the ids of the vectors. Is there any method to get all the ids of the vectors.
ok I have struggled with this alot but finally I have found the solution, I was just trying to make my first hello world with pinecone and I added some data and to make sure it is really upserted I wanted to get all vectors back from a namespace
topK
to its maximum and you will all vectors no matter what is your queryfor example I have only 54 vectors in my pinecone index so if I set topK
to 100
it returns me all documents no matter what I give in query or I leave empty text in query,
here is my code for the reference sorry it is in ES Module (javascript) but I am sure it will work the same in python:
const queryPineconeIndex = async (queryText, numberOfResults) => {
const response = await openai.createEmbedding({
model: "text-embedding-ada-002",
input: queryText,
});
const vector = response?.data?.data[0]?.embedding
console.log("vector: ", vector);
// [ 0.0023063174, -0.009358601, 0.01578391, ... , 0.01678391, ]
const index = pinecone.Index(process.env.PINECONE_INDEX_NAME);
const queryResponse = await index.query({
queryRequest: {
vector: vector,
// id: "vec1",
topK: numberOfResults,
includeValues: true,
includeMetadata: true,
namespace: process.env.PINECONE_NAME_SPACE
}
});
queryResponse.matches.map(eachMatch => {
console.log(`score ${eachMatch.score.toFixed(1)} => ${JSON.stringify(eachMatch.metadata)}\n\n`);
})
console.log(`${queryResponse.matches.length} records found `);
}
queryPineconeIndex("any text or empty string", 100)
if you don't know how many vectors you have in an index you can also get it like this:
const getIndexStats = async () => {
const indexesList = await pinecone.listIndexes();
console.log("indexesList: ", indexesList);
const index = pinecone.Index(process.env.PINECONE_INDEX_NAME);
const indexStats = await index.describeIndexStats({
describeIndexStatsRequest: {
filter: {},
},
});
console.log("indexStats: ", indexStats);
}
// getIndexStats()
