如何删除松果索引的命名空间中的所有向量?

Question

我正面临着一个挑战，当它涉及到在pinecone的命名空间中删除向量。我正在使用javascript并试图删除命名空间中的所有向量，我得到这个错误"[ErrorWithoutStackTrace:没有提供的id]"，有人知道为什么这是以及如何解决它吗?提前感谢

我已经尝试使用这段代码，" await index.delete1([]， true， " example-namespace "); "在松果文档的名称空间部分的删除向量中指定，但我得到上面提到的错误，

Answer 1

我找到了一个解决方案:

await index.delete1({
deleteAll: true,
namespace,
});

我从Pinecone GitHub repo得到了这个。

Answer 2

const index = pinecone.Index("your_index_name");
await index.delete1({
deleteAll: true,
namespace: "your_namespace_name"
});

Answer 3

这是我写的一个node.js脚本，用于删除所有命名空间中的所有向量:

(async () => {
// Import the PineconeClient
const { PineconeClient } = require('@pinecone-database/pinecone');
const axios = require('axios'); // Ensure axios is imported
// Declare your API key and environment
const PINECONE_API_KEY = process.env.PINECONE_API_KEY;
const PINECONE_ENVIRONMENT = 'asia-northeast-gcp'; // replace with your environment
// Create the client
const client = new PineconeClient();
// Initialize the client
await client.init({
apiKey: PINECONE_API_KEY,
environment: PINECONE_ENVIRONMENT,
});
// select my index
const index = client.Index('atheneum');
// get all of the namespaces using curl equivalent and parsing the response
let namespacesArr = [];
try {
// Make a GET request
const url = `${process.env.PINECONE_API_ENDPOINT}/describe_index_stats`;
const response = await axios.get(url, {
headers: {
'Api-Key': PINECONE_API_KEY,
},
});
// Parse the response
namespacesArr = Object.keys(response.data.namespaces);
console.log(namespaces);
} catch (error) {
console.error('error describing index', error);
}
// iterate through namespaces and delete all indexes
for (const namespace of namespacesArr) {
try {
await index.delete1({
deleteAll: true,
namespace,
});
console.log(`Deleted all vectors in namespace: ${namespace}`);
} catch (error) {
console.error(
`Error deleting vectors in namespace: ${namespace}`,
error
);
}
}
})();

如果你只想删除一个命名空间，你可以这样修改它:

let namespacesArr = ["your namespace that you want to delete"];
// iterate through namespaces and delete all indexes
for (const namespace of namespacesArr) {
try {
await index.delete1({
deleteAll: true,
namespace,
});
console.log(`Deleted all vectors in namespace: ${namespace}`);
} catch (error) {
console.error(
`Error deleting vectors in namespace: ${namespace}`,
error
);
}
}

你必须安装axios和pinecone客户端库:

npm install --save-dev axios
npm install --save-dev @pinecone-database/pinecone

然后你可以像这样运行脚本:

node ./path/to/script/node-delete-all-indexes.js

Answer 4

const deleteAllVectorsOfIndex = async () => {
const index = pinecone.Index(process.env.PINECONE_INDEX_NAME);
const deleteResponse = await index.delete1({
deleteAll: true,
namespace: process.env.PINECONE_NAME_SPACE
})
console.log("deleteResponse: ", deleteResponse);
}
deleteAllVectorsOfIndex();

Answer 5

pinecone库升级到版本1后，代码如下:

const pineconeClient = new Pinecone({
apiKey: PINECONE_API_KEY,
environment: PINECONE_ENVIRONMENT
})
const index = pineconeClient.Index(indexName)
const namespaceIndex = index.namespace(nameSpace);
const res = await namespaceIndex.deleteAll();
