Creating and loading private datasets


This document explains how to create, upload, and list your dataset for use by other Pinecone users. This guide shows how to create your own dataset using your own storage; you cannot upload your own dataset to the Pinecone dataset directory.

To learn about using existing Pinecone datasets, see Working with datasets.

Creating a dataset


The Pinecone datasets project uses poetry for dependency management and supports python versions 3.8+.

To install poetry, run the following command from the project root directory:

poetry install --with dev

Dataset metadata

To create a public dataset, you may need to generate dataset metadata.


The following example creates a metadata object meta containing metadata for a dataset test_dataset.

from pinecone_datasets.catalog import DatasetMetadata

meta = DatasetMetadata(
    created_at="2023-02-17 14:17:01.481785",
    dense_model={"name": "bert", "dimension": 3},
    sparse_model={"name": "bm25"},

If you intend to list your dataset, you can save the dataset metadata using the following command. Write permission to location is needed.

dataset._save_metadata("non-listed-dataset", meta)

Viewing dataset schema

To see the complete schema, run the following command:


Running tests

To run tests locally, run the following command:

poetry run pytest --cov pinecone_datasets

Uploading and listing a dataset

Pinecone datasets can load a dataset from any storage bucket where it has access using the default access controls for s3, gcs or local permissions.

Pinecone datasets expects data to be uploaded with the following directory structure:

Figure 1: Expected directory structure for Pinecone datasets

├── base_path # path to where all datasets
│ ├── dataset_id # name of dataset
│ │ ├── metadata.json # dataset metadata (optional, only for listed)
│ │ ├── documents # datasets documents
│ │ │ ├── file1.parquet
│ │ │ └── file2.parquet
│ │ ├── queries # dataset queries
│ │ │ ├── file1.parquet
│ │ │ └── file2.parquet
└── ...

Pinecone datasets scans storage and lists every dataset with metadata file.


The following shows the format of an example s3 bucket address for a datasets metadata file:


Using your own dataset

By default, the Pinecone client uses Pinecone's public datasets bucket on GCS. You can use your own bucket by setting the PINECONE_DATASETS_ENDPOINT environment variable.


The following export command changes the default dataset storage endpoint to gs://my-bucket. Calling list_datasets or load_dataset now scans that bucket and list all datasets.

export PINECONE_DATASETS_ENDPOINT="gs://my-bucket"

You can also use s3:// as a prefix to your bucket to access an s3 bucket.

Authenticating to your own storage bucket

Pinecone Datasets supports GCS and S3 storage buckets, using default authentication as provided by the fsspec implementation: gcsfs for GCS and s3fs for AWS.

To authenticate to an AWS s3 bucket using the key/secret method, follow these steps:

  1. Set a new endpoint by setting the environment variable PINECONE_DATASETS_ENDPOINT to the s3 address for your bucket.


export PINECONE_DATASETS_ENDPOINT="s3://my-bucket"
  1. Use the key and secret parameters to pass your credentials to the list_datasets and load_dataset functions.


st = list_datasets(

ds = load_dataset(

Accessing a non-listed dataset

To access a non-listed dataset, load it directly using the Dataset constructor.


The following loads the dataset non-listed-dataset.

from pinecone_datasets import Dataset

dataset = Dataset("non-listed-dataset")
