Datasets allow you to store and reuse well-defined data for use in experiments. Datasets can be stored and versioned in Galileo, and available for experiments running both in the console as well as in code.

​
Dataset fields

Each record in a Galileo dataset can have three top-level fields:

  1. input - Input variables that can be passed to your application to recreate a test case.
  2. output - Reference outputs to evaluate your application. These can be the ground truth for BLEU, ROUGE, and Ground Truth Adherence metrics, or reference outputs for manual reference.
  3. metadata - Additional data you can use to filter or group your dataset.

​
Create Datasets

When you create a dataset, it is uploaded to Galileo and available to future experiments. Datasets need to have unique names, and are available to all projects across your organization.

from galileo.datasets import create_dataset

# Create a dataset with test data
test_data = [
    {
        "input": "Which continent is Spain in?",
        "output": "Europe",
    },
    {
        "input": "Which continent is Japan in?",
        "output": "Asia",
    },
]

dataset = create_dataset(
    name="countries",
    content=test_data
)

See the create_dataset Python SDK docs or createDataset TypeScript SDK docs for more details.

​
Get Existing Datasets

Once a dataset has been created in Galileo, you can retrieve it to use in your experiments by name or ID.

from galileo.datasets import get_dataset

# Get a dataset by name
dataset = get_dataset(
    name="countries"
)

# Get a dataset by ID
dataset = get_dataset(
    id="dataset-id"
)

# Get its content
dataset.get_content()

See the get_dataset Python SDK docs or getDataset TypeScript SDK docs for more details.

​
Add Rows to Existing Datasets

from galileo.datasets import get_dataset

# Get an existing dataset
dataset = get_dataset(
    name="countries"
)

# Add new rows to the dataset
dataset.add_rows([
    {
        "input": "Which continent is Morocco in?",
        "output": "Africa",
    },
    {
        "input": "Which continent is Australia in?",
        "output": "Oceania",
    },
])

See the add_rows Python SDK docs for more details.

​
List Datasets

You can retrieve all the datasets for a project.

from galileo.datasets import list_datasets

# List all datasets in a project
datasets = list_datasets()

# List datasets with a custom limit
datasets = list_datasets(
    limit=50,
)

See the list_datasets Python SDK docs or getDatasets TypeScript SDK docs for more details.

​
Delete Datasets

If a dataset is no longer needed, you can delete it by name or ID.

from galileo.datasets import delete_dataset

# Delete a dataset by name
delete_dataset(name="countries")

# Delete a dataset by ID
delete_dataset(id="dataset-id")

See the delete_dataset Python SDK docs or deleteDataset TypeScript SDK docs for more details.

​
Work with Dataset Versions

Galileo automatically creates new versions of datasets when they are modified. You can access different versions by getting the dataset history.

from galileo.datasets import get_dataset_version_history

# Get the version history
dataset = get_dataset_version_history(
    dataset_name="countries"
)

# List out the rows added with each version
for dataset in datasets.versions:
    print(f"""
    Version index: {dataset.version_index},
    rows added: {dataset.rows_added}
    """)

See the get_dataset_version_history Python SDK docs for more details.

​
Use Datasets in Experiments

Datasets are primarily used for running experiments to evaluate the performance of your LLM applications:

from galileo.datasets import get_dataset
from galileo.experiments import run_experiment
from galileo.prompts import get_prompt_template
from galileo.schema.metrics import GalileoScorers

# Get an existing dataset
dataset = get_dataset(
    name="countries"
)

# Get an existing prompt template
prompt_template = get_prompt_template(
    project="my-project",
    name="geography-prompt"
)

# Run an experiment with the dataset and prompt
results = run_experiment(
    "geography-experiment",
    dataset=dataset,
    prompt_template=prompt_template,
    metrics=[GalileoScorers.Completeness],
    project="my-project",
)
