I don’t have an existing database. Which data should I use to run the examples?

To build up your own database, you can use the Activity browser. To become familiar with it, please refer to its documentation here.

Alternatively, you can find a dummy project within this package. Go to the test folder and download create_dummy_project.py. Once you have run this script, you will have created a dummy project to do first calculations. The project contains three different databases: “biosphere3”, “background” and “foreground”. The last one can be used as the demand activity for the examples. So set the values in Getting Started as you see below.

# your default project name
bw.projects.set_current("moca_test_project")

# your default database to work with
demand = {bw.Database("foreground").get("fg_activity_0"): 1}.

Now you can experiment and work with your new project. To get started, check out the Code Examples.
