LabelSourceConfig#

Note

All Configs are derived from rastervision.pipeline.config.Config, which itself is a pydantic Model.

Config:
  • extra: str = forbid

  • validate_assignment: bool = True

Fields:
field type_hint: Literal['label_source'] = 'label_source'#
build(class_config: ClassConfig, crs_transformer: CRSTransformer, bbox: Box | None = None, tmp_dir: str | None = None) LabelSource[source]#

Build an instance of the corresponding type of object using this config.

For example, BackendConfig will build a Backend object. The arguments to this method will vary depending on the type of Config.

Parameters:
Return type:

LabelSource

classmethod deserialize(inp: str | dict | Config) Self#

Deserialize Config from a JSON file or dict, upgrading if possible.

If inp is already a Config, it is returned as is.

Parameters:

inp (str | dict | Config) – a URI to a JSON file or a dict.

Return type:

Self

classmethod from_dict(cfg_dict: dict) Self#

Deserialize Config from a dict.

Parameters:

cfg_dict (dict) – Dict to deserialize.

Return type:

Self

classmethod from_file(uri: str) Self#

Deserialize Config from a JSON file, upgrading if possible.

Parameters:

uri (str) – URI to load from.

Return type:

Self

recursive_validate_config()#

Recursively validate hierarchies of Configs.

This uses reflection to call validate_config on a hierarchy of Configs using a depth-first pre-order traversal.

revalidate()#

Re-validate an instantiated Config.

Runs all Pydantic validators plus self.validate_config().

to_file(uri: str, with_rv_metadata: bool = True) None#

Save a Config to a JSON file, optionally with RV metadata.

Parameters:
  • uri (str) – URI to save to.

  • with_rv_metadata (bool) – If True, inject Raster Vision metadata such as plugin_versions, so that the config can be upgraded when loaded.

Return type:

None

update(pipeline: RVPipelineConfig | None = None, scene: SceneConfig | None = None) None[source]#

Update any fields before validation.

Subclasses should override this to provide complex default behavior, for example, setting default values as a function of the values of other fields. The arguments to this method will vary depending on the type of Config.

Parameters:
Return type:

None

validate_config()#

Validate fields that should be checked after update is called.

This is to complement the builtin validation that Pydantic performs at the time of object construction.

validate_list(field: str, valid_options: list[str])#

Validate a list field.

Parameters:
  • field (str) – name of field to validate

  • valid_options (list[str]) – values that field is allowed to take

Raises:

ConfigError – if field is invalid
