## Description

A meta package to load all related Machine Learning libraries in Pharo.

For more information about the naming convention or the requirement to be integrated in Pharo-AI, refere to the [Contribution file](CONTRIBUTION.md).

## Installation

You can load all the Artificial Intelligence packages from the pharo-ai project into a fresh Pharo image by going to the Playground (Ctrl + OW/Cmd + OW) and executing the following expression (select it and press Do-it button or Ctrl+D/Cmd+D):

```smalltalk
EpMonitor disableDuring: [
    Metacello new
        baseline: 'AIPharo';
        repository: 'github://pharo-ai/ai/src';
	onWarningLog;
	onConflictUseIncoming;
        load ]
```

This should load the default version of the AIPharo (you can also specify another version or branch).

To add it to your Baseline:

```smalltalk
    spec
	    baseline: 'AIPharo'
	    with: [ spec repository: 'github://pharo-ai/ai/src' ]
```

If you are new to baselines and Metacello, check out the [Baselines](https://github.com/pharo-open-documentation/pharo-wiki/blob/master/General/Baselines.md) tutorial on Pharo Wiki.
