FV3Config

FV3Config is used to configure and manipulate run directories for FV3GFS.

• Free software: BSD license

Basic usage

from fv3config import write_run_directory

with open("config.yml", 'r') as f:
    config = yaml.safe_load(f)
write_run_directory(config, './rundir')

config is a configuration dictionary which contains namelists, input data specifications, and other options. It can be edited just like any dictionary.

For more in-depth usage, please refer to the documentation. This can be generated with make docs.

History

v0.5.1

• Fix formatting of this changelog for PyPI

v0.5.0

Breaking changes:

• enable_restart function now requires an initial_conditions argument. It also sets force_date_from_namelist to False.

Major changes:

• a new public function fv3gfs.get_bytes_asset_dict

• a new command line interface write_run_directory

• removed integration tests for run_docker and run_native which actually executed the model

• all tests are now offline, using a mocked in-memory gcsfs to represent remote communication.

• add a Dockerfile to produce a lightweight image with fv3config installed

• Add new public functions fv3config.get_nudging_assets and fv3config.update_config_for_nudging.

• Add CLI entry points for enable_restart and update_config_for_nudging.

Minor changes:

• updated create_rundir example to accept external arguments

• refactor get_current_date function to not require the path to the INPUT directory.

v0.4.0 (2020-07-09)

Major changes:

• the old “default” data options are removed

• orographic_forcing is now a required configuration key

• get_default_config() is removed, with a placeholder which says it was removed

• ensure_data_is_downloaded is removed, with a placeholder which says it was removed

v0.3.2 (2020-04-16)

Major changes:

• filesystem operations now manually backoff with a 1-minute max time on RuntimeError (which gcsfs often raises when it shouldn’t) and gcsfs.utils.HttpError

• put_directory now makes use of a thread pool to copy items in parallel.

Minor changes:

• run_docker now works when supplying an outdir on google cloud storage

• put_directory is now marked as package-private instead of module-private

v0.3.1 (2020-04-08)

Major changes:

• Add get_timestep and config_from_yaml functions

Minor changes:

• Allow config_to_yaml to write to remote locations

• Control whether outputs are logged to console or not in run_kubernetes, run_native, and run_docker.

Breaking changes

• Print stderr and stdout to the console by default when using fv3run. Use the –capture-output command-line flag to enable the previous behavior.

v0.3.0 (2020-04-03)

Major changes:

• Added –kubernetes command-line flag to output a kubernetes config yaml to stdout

Minor changes:

• Added the flag --mca btl_vader_single_copy_mechanism none to mpirun in fv3run to mpirun in fv3run

• Add ReadTheDocs configuration file

• Do not require output dir and fv3config to be remote in run_kubernetes

• Fix bug when submitting k8s jobs with images that have an “_” in them

Breaking changes

• Refactored run_kubernetes and run_docker to call run_native via a new API serializing their args/kwargs as json strings. The fv3config version in a docker image must be greater than or equal inside a container to outside, or a silent error will occur.

• When output location is set to a local path, the job now runs in that output location instead of in a temporary directory which then gets copied. This is done both to reduce copying time for large jobs, and to improve visibility of model behavior while running.

0.2.0 (2020-01-27)

• Began tagging version commits

0.1.0 (2019-10-11)

• Initial pre-alpha release
