pip install pinecone-datasetsYou can use Pinecone Datasets to load our public datasets or with your own datasets. Datasets library can be used in 2 main ways: ad-hoc loading of datasets from a path or as a catalog loader for datasets.
Pinecone hosts a public datasets catalog, you can load a dataset by name using list_datasets and load_dataset functions. This will use the default catalog endpoint (currently GCS) to list and load datasets.
from pinecone_datasets import list_datasets, load_dataset
list_datasets()
# ["quora_all-MiniLM-L6-bm25", ... ]
dataset = load_dataset("quora_all-MiniLM-L6-bm25")
dataset.head()

we expect data to be uploaded to the following directory structure:
├── my-subdir # path to where all datasets
│ ├── my-dataset # 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
└── ...
The data schema is expected to be as follows:
documentsdirectory contains parquet files with the following schema:- Mandatory:
id: str, values: list[float] - Optional:
sparse_values: Dict: indices: List[int], values: List[float],metadata: Dict,blob: dict- note: blob is a dict that can contain any data, it is not returned when iterating over the dataset and is inteded to be used for storing additional data that is not part of the dataset schema. however, it is sometime useful to store additional data in the dataset, for example, a document text. In future version this may become a first class citizen in the dataset schema.
- Mandatory:
queriesdirectory contains parquet files with the following schema:- Mandatory:
vector: list[float], top_k: int - Optional:
sparse_vector: Dict: indices: List[int], values: List[float],filter: Dict- note: filter is a dict that contain pinecone filters, for more information see here
- Mandatory:
in addition, a metadata file is expected to be in the dataset directory, for example: s3://my-bucket/my-dataset/metadata.json
from pinecone_datasets.catalog import DatasetMetadata
meta = DatasetMetadata(
name="test_dataset",
created_at="2023-02-17 14:17:01.481785",
documents=2,
queries=2,
source="manual",
bucket="LOCAL",
task="unittests",
dense_model={"name": "bert", "dimension": 3},
sparse_model={"name": "bm25"},
)full metadata schema can be found in pinecone_datasets.catalog.DatasetMetadata.schema
To set you own catalog endpoint, set the environment variable DATASETS_CATALOG_BASEPATH to your bucket. Note that pinecone uses the default authentication method for the storage type (gcsfs for GCS and s3fs for S3).
export DATASETS_CATALOG_BASEPATH="s3://my-bucket/my-subdir"from pinecone_datasets import list_datasets, load_dataset
list_datasets()
# ["my-dataset", ... ]
dataset = load_dataset("my-dataset")additionally, you can load a dataset from the Dataset class
from pinecone_datasets import Dataset
dataset = Dataset.from_catalog("my-dataset")You can load your own dataset from a local path or a remote path (GCS or S3). Note that pinecone uses the default authentication method for the storage type (gcsfs for GCS and s3fs for S3).
from pinecone_datasets import Dataset
dataset = Dataset.from_path("s3://my-bucket/my-subdir/my-dataset")This assumes that the path is structured as described in the Expected dataset structure section
Pinecone Datasets enables you to load a dataset from a pandas dataframe. This is useful for loading a dataset from a local file and saving it to a remote storage.
The minimal required data is a documents dataset, and the minimal required columns are id and values. The id column is a unique identifier for the document, and the values column is a list of floats representing the document vector.
import pandas as pd
df = pd.read_parquet("my-dataset.parquet")
metadata = DatasetMetadata(**metadata_dict)
dataset = Dataset.from_pandas(documents = df, queries = None, metadata = metadata)Please check the documentation for more information on the expected dataframe schema. There's also a column mapping variable that can be used to map the dataframe columns to the expected schema.
Pinecone Datasets is build on top of pandas. This means that you can use all the pandas API to access the data. In addition, we provide some helper functions to access the data in a more convenient way.
accessing the documents and queries dataframes is done using the documents and queries properties. These properties are lazy and will only load the data when accessed.
document_df: pd.DataFrame = dataset.documents
query_df: pd.DataFrame = dataset.queriesOne of the main use cases for Pinecone Datasets is iterating over a dataset. This is useful for upserting a dataset to an index, or for benchmarking. It is also useful for iterating over large datasets - as of today, datasets are not yet lazy, however we are working on it.
# List Iterator, where every list of size N Dicts with ("id", "values", "sparse_values", "metadata")
dataset.iter_documents(batch_size=n)
# Dict Iterator, where every dict has ("vector", "sparse_vector", "filter", "top_k")
dataset.iter_queries()Pinecone dataset ship with a blob column which is inteneded to be used for storing additional data that is not part of the dataset schema. however, it is sometime useful to store additional data in the dataset, for example, a document text. We added a utility function to move data from the blob column to the metadata column. This is useful for example when upserting a dataset to an index and want to use the metadata to store text data.
from pinecone_datasets import import_documents_keys_from_blob_to_metadata
new_dataset = import_documents_keys_from_blob_to_metadata(dataset, keys=["text"])you can save your dataset to a catalog managed by you or to a local path or a remote path (GCS or S3).
To set you own catalog endpoint, set the environment variable DATASETS_CATALOG_BASEPATH to your bucket. Note that pinecone uses the default authentication method for the storage type (gcsfs for GCS and s3fs for S3).
After this environment variable is set you can save your dataset to the catalog using the save function
from pinecone_datasets import Dataset
metadata = DatasetMetadata(**{"name": "my-dataset", ...})🚨 NOTE Dataset name in the metadata must match the dataset_id parameter you pass to the catalog, in this example 'my-dataset'
dataset = Dataset.from_pandas(documents, queries, metadata)
dataset.to_catalog("my-dataset")You can save your dataset to a local path or a remote path (GCS or S3). Note that pinecone uses the default authentication method for the storage type (gcsfs for GCS and s3fs for S3).
dataset = Dataset.from_pandas(documents, queries, metadata)
dataset.to_path("s3://my-bucket/my-subdir/my-dataset")When upserting a Dataset to an Index, only the document data will be upserted to the index. The queries data will be ignored.
TODO: add example for API Key adn Environment Variables
ds = load_dataset("dataset_name")
ds.to_pinecone_index("index_name")
# or, if you run in notebook environment
await ds.to_pinecone_index_async("index_name")the to_pinecone_index function also accepts additional parameters:
batch_sizefor controlling the upserting processapi_keyfor passing your API key, otherwise you cankwargs- for passing additional parameters to the index creation process
