When running Python model adapters within FEWS, Python should be installed on your system and the dependencies (Python packages) of your adapter as well. The proposed way to do this is to:

• work in virtual environment
• organize model adapter code as python package

• make sure that all dependencies are listed in the setup.py of the package, to allow straightforward installation
