# Sample Data¶

Harmonica provides some sample data for testing through the harmonica.datasets module. The sample data are automatically downloaded from the Github repository to a folder on your computer the first time you use them. After that, the data are loaded from this folder. The download is managed by the pooch package.

## Where is my data?¶

The data files are downloaded to a folder ~/.harmonica/data/ by default. This is the base data directory. pooch will create a separate folder in the base directory for each version of Harmonica. For example, the base data dir for v0.1.0 is ~/.harmonica/data/v0.1.0. If you’re using the latest development version from Github, the version is master.

You can change the base data directory by setting the HARMONICA_DATA_DIR environment variable to a different path.
