A note on the version number

Alfred3 is currently at version 1.x.x, because it is already in use for research. However, it does currently lack comprehensive documentation and automatic unit testing. Also, some of its most powerful extensions are not currently publicly available. Currently, we lack the resources to upgrade our documentation and testing capacities, focusing mainly on maintaining the current state of the library.

If you want to use alfred3, please contact us via


If you have Python 3 installed, you can install alfred3 via pip with the follwoing command. It is best practice to install Alfred3 in a new virtual environment for every project (see virtualenv package).

pip install alfred3
