Hello @YIN-Renlong! Good to see you here again. I hope you're having a great day.
The error you're encountering is due to the size of the data being ingested exceeding the limit set by Pinecone. This is likely happening because the chunkSize
parameter in the RecursiveCharacterTextSplitter
function is set too high for the size of your PDF files.
The chunkSize
parameter determines the size of the text chunks that are being processed. If the message length is too large, reducing the chunkSize
should help. Currently, the chunkSize
is set to 1000 in the ingest-data.ts
script:
const textSplitter = new RecursiveCharacterTextSplitter({
chunkSize: 1000,
chunkOverlap: 200,
});
You can try reducing the chunkSize
to a smaller value, for example, 500:
const textSplitter = new RecursiveCharacterTextSplitter({
chunkSize: 500, // reduce chunkSize from 1000 to 500
chunkOverlap: 200,
});
Please note that reducing the chunkSize
will increase the number of chunks and may affect the performance of the ingestion process. It's important to find a balance between the chunk size and the performance that suits your specific use case.
You can find the ingest-data.ts
script in the repository here.
Let me know if this helps or if you need further assistance.

@dosubot thanks. According to your plan, I changed the value from 1000 to 500 (chunkSize: 1000 to chunkSize: 500). However, the problem still arises and I got this error:

This means that your solution may not be successful in solving the problem. So, do you have a better opinion?

Based on the error message you're encountering, it seems that the size of the data you're trying to upsert into Pinecone is exceeding its limit. Even though you've reduced the chunkSize
parameter in the RecursiveCharacterTextSplitter
function, the data size might still be too large due to the size of the embeddings created by the OpenAIEmbeddings
class.
One solution could be to further reduce the chunkSize
parameter. However, this might not be the most efficient solution as it could lead to a large number of very small chunks.
Another solution could be to modify the OpenAIEmbeddings
class to produce smaller embeddings. This could involve using a different model or reducing the dimensionality of the embeddings. However, this might affect the quality of the embeddings and therefore the performance of your chatbot.
A third solution could be to implement a check in the PineconeStore.fromDocuments
method to ensure that the size of the data being upserted does not exceed Pinecone's limit. If the data size is too large, you could split the data into smaller batches and upsert them separately. Here's a rough example of how you could implement this:
const BATCH_SIZE = 100; // Adjust this value as needed
// ...
const docs = await textSplitter.splitDocuments(rawDocs);
// ...
const embeddings = new OpenAIEmbeddings();
const index = pinecone.Index(PINECONE_INDEX_NAME);
// Split docs into batches
for (let i = 0; i < docs.length; i += BATCH_SIZE) {
const batch = docs.slice(i, i + BATCH_SIZE);
// Embed and upsert each batch separately
await PineconeStore.fromDocuments(batch, embeddings, {
pineconeIndex: index,
namespace: PINECONE_NAME_SPACE,
textKey: 'text',
});
}
This code splits the documents into batches and upserts each batch separately, which should help to avoid exceeding Pinecone's data size limit. Please adjust the BATCH_SIZE
as needed to fit your specific use case.
In addition to the above, you might want to check the following points based on similar issues in the repository:
You can find more details about these points in the following issues: npm run ingest / Pinecone error, Pinecone Ingest Error, and Error: Failed to ingest your data.
I hope this helps! If you have any other questions or need further clarification, feel free to ask.

Hi, @YIN-Renlong
I'm helping the gpt4-pdf-chatbot-langchain team manage their backlog and am marking this issue as stale. It looks like you encountered the "PineconeError: Error, message length too large" issue during the ingest process for certain PDF files, and you were seeking a solution to fix this issue when running npm run ingest
. Despite attempting to reduce the chunkSize
parameter in the RecursiveCharacterTextSplitter
function as a suggested solution, the error persisted, and you requested further debugging steps.
Could you please confirm if this issue is still relevant to the latest version of the gpt4-pdf-chatbot-langchain repository? If it is, please let the gpt4-pdf-chatbot-langchain team know by commenting on this issue. Otherwise, feel free to close the issue yourself, or it will be automatically closed in 7 days. Thank you!
Hi everyone, for some pdf files, I get the following error during ingest process
