Datasets library is used to load datasets in Pharo. The datasets are loaded as DataFrame objects.

Installation

To install Datasets, go to the Playground (Ctrl+OW) in your Pharo image and execute the following Metacello script (select it and press Do-it button or Ctrl+D):

Metacello new
  baseline: 'AIDatasets';
  repository: 'github://pharo-ai/datasets';
  load.

If you want to depend on it

spec 
   baseline: 'AIDatasets' 
   with: [ spec repository: 'github://pharo-ai/datasets' ].

Usage

To load a dataset, using AIDataSets loadXYZ. For example:

AIDatasets loadBostonHousing.
AIDatasets loadBreastCancer.
AIDatasets loadWine.
AIDatasets loadDiabetes.
AIDatasets loadDigits.
AIDatasets loadMnistTest.
AIDatasets loadIris.
AIDatasets loadOldFaithful.

Loading a new dataset involves downloading the CSV file into the data/ directory in the local folder of your image. Then the data is read from the file and returned to you as a DataFrame object.
