Unable to pip install

Version 3 of Python uses pip3. Use the following commands at the command line (the terminal):

pip3 install -U pinecone-client

Slow uploads or high latencies

To minimize latency when accessing Pinecone:

  • Switch to a cloud environment. For example: EC2, GCE, Google Colab, GCP AI Platform Notebook, or SageMaker Notebook. If you experience slow uploads or high query latencies, it might be because you are accessing Pinecone from your home network.
  • Consider deploying your application in the same environment as your Pinecone service. For users on the Starter (free) plan, the environment is GCP US-West (Oregon).
  • See performance tuning for more tips.

High query latencies with batching

If you're batching queries, try reducing the number of queries per call to 1 query vector. You can make these calls in parallel and expect roughly the same performance as with batching.

Upsert throttling when using the gRPC client

It's possible to get write-throttled sooner when upserting using the gRPC index. If you see this often, then we recommend using a backoff algorithm while upserting.

Pods are full

There is a limit to how much vector data a single pod can hold. Create an index with more pods to hold more data. Estimate the right index configuration and scale your index to increase capacity.

If your metadata has high cardinality, such as having a unique value for every vector in a large index, the index will take up more memory than estimated. This could result in the pods being full sooner than you expected. Consider only indexing metadata to be used for filtering, and storing the rest in a separate key-value store.

See the Manage Indexes documentation for information on how to specify the number of pods for your index.

Security concerns

We work hard to earn and maintain trust by treating security and reliability as a cornerstone of our company and product. Pinecone is SOC 2 Type II compliant and GDPR-ready. See the Trust & Security page for more information. Contact us to report any security concerns.

CORS errors

When sending requests to Pinecone, you may receive the following error:

No 'Access-Control-Allow-Origin' header is present on the requested resource.

This error occurs in response to cross-origin requests. Most commonly, it occurs when a user is running a local web server with the hostname 'localhost', which Pinecone's Same Origin Policy (SOP) treats as distinct from the IP address of the local machine.

To resolve this issue, host your web server on an external server with a public IP address and DNS name entry.
