This dataset is derived from the Dominick’s OJ dataset and includes extra simulated data to simultaneously train thousands of models on Azure Machine Learning.

This dataset is provided under the original terms that Microsoft received source data. The dataset may include data sourced from Microsoft.

The data contains weekly sales of orange juice over 121 weeks. There are 3,991 stores included and three brands of orange juice per store so that 11,973 models can be trained.

Data access

Azure Notebooks

from azureml.core.workspace import Workspace
ws = Workspace.from_config()
datastore = ws.get_default_datastore()

from azureml.opendatasets import OjSalesSimulated

Read data from Azure Open Datasets

# Create a Data Directory in local path
import os

oj_sales_path = "oj_sales_data"

if not os.path.exists(oj_sales_path):
    os.mkdir(oj_sales_path)

# Pull all of the data
oj_sales_files = OjSalesSimulated.get_file_dataset()

# or pull a subset of the data
oj_sales_files = OjSalesSimulated.get_file_dataset(num_files=10)

oj_sales_files.download(oj_sales_path, overwrite=True)

Upload the individual datasets to Blob Storage

We upload the data to Blob and will create the FileDataset from this folder of csv files.

target_path = 'oj_sales_data'

datastore.upload(src_dir = oj_sales_path,
                target_path = target_path,
                overwrite = True, 
                show_progress = True)

Create the file dataset

We need to define the path of the data to create the FileDataset.

from azureml.core.dataset import Dataset

ds_name = 'oj_data'
path_on_datastore = datastore.path(target_path + '/')

input_ds = Dataset.File.from_files(path=path_on_datastore, validate=False)

Register the file dataset to the workspace

We want to register the dataset to our workspace so we can call it as an input into our Pipeline for forecasting.

registered_ds = input_ds.register(ws, ds_name, create_new_version=True)
named_ds = registered_ds.as_named_input(ds_name)
