- Generate a Brightway-compatible, custom foreground inventory database from a human-readable Excel workbook.
- Automatically validate the foreground database and connect to ecoinvent and biosphere.
- Under development, not yet implemented: automatically perform one or more impact assessment calculations.
- Install package dependencies using either requirements.txt with pip or autobw_conda.yml with conda
- It's recommended to also install Brightway's Activity Browser in a separate environment
- Ecoinvent must be imported into your Brightway project manually. Biosphere will be imported on running autoBW, if needed.
- The name of the ecoinvent database used in your project must match between the project, the config files and the foreground database import file.
- Detailed output is saved to a log file for every autoBW run.
- By default this file is named bwconfig.yaml.
create_new_projectdefaults to False. Because ecoinvent must be imported manually, autobw cannot currently be used to create a complete project with all background database.data_directoryis the full path to directory where the config files are located. This location will also be where output files and graphics will be saved.
- By default this file is named caseconfig.yaml.
- Use the provided file to specify the local Brightway projects, which (background) databases should be included in the project, and details about the foreground database to create.
fg_db_importshould the the name of the Excel file containing the foreground data. See the provided import_template.xlsx for guidance.- Set
generate_keysto False if you have provided unique activity and exchange keys for all newly created activities and exchanges in the foreground data. Otherwise UUIDs will be generated and assigned automatically.
- autoBW can be run from an IDE or from the command line. If using Visual Studio Code, the following launch.json structure can be used to set up runs:
{
"version": "0.2.0",
"configurations": [
{
"name": "Python: Current File",
"type": "python",
"request": "launch",
"program": "${file}",
"env": {
"PYTHONPATH": "${workspaceFolder};[location of autobw codebase]"
},
"console": "integratedTerminal",
"args": [
"--data","[path to data diectory]",
"--bwconfig", "bwconfig.yaml",
"--caseconfig", "caseconfig.yaml"
],
}
]
}
- Command line arguments are
--data, the path to the data directory,--bwconfig, the Brightway config file name with extension, and--caseconfig, the case study config file name with extension.
