Running the model

Setting input and output directories

The input data files, config file, and output directory can all be in locations of your choice, and these locations are specified as command line arguments when you run the model. If they aren’t specified, defaults will be used.

Default input and output directories:

From the package’s root directory: * Input meteorological data: data/ * Input configuration file: model_config.yml * Model output and logs: output/

If using the default output directory, a directory output/ will be created if it doesn’t already exist.

Running the model from the command line

Run the model by running the fetch3 module.

Important

fetch3’s conda environment must be activated to run the model!

To specify an input config file, data directory, or output directory in a location other than the default, different directories can be specified as command line arguments, for example:

python -m fetch3 --config_path /Users/username/fetch3/user_model_config.yml
--data_path /Users/username/fetch3/user_data/ --output_path /Users/username/fetch3/output/

Note

Replace the paths and filenames in this example with the actual paths and files you are using.

If the arguments --config_path, --data_path, and --output_path are omitted when running the model from the command line, the defaults will be used.
