SaveDatasetUnit
Write the dataset back to the path it was loaded from.
Takes no configuration: the destination is dataset_path, published by
whichever unit loaded the dataset, so a save can never land somewhere the
load did not come from. Declares no outputs — its result is on disk, not in
the context.
The error message keeps the original exception's text. A failure here is an
infrastructure failure (out of space, permissions, a path the filesystem
rejects), and only the message of the outermost error reaches the user: the
job queue stores str(exc), never the __cause__ chain. Swallowing it
would drop the diagnosis exactly when it is needed.
Methods
execute(self, ctx: DashAI.back.units.context.ExecutionContext) -> None
SaveDatasetUnitDo the unit's work, reading from and writing to the context.
Parameters
- ctx : ExecutionContext
- The shared execution context.
get_credential(self, name: str)
ConfigObjectResolve a registered credential component by name.
Parameters
- name : str
- Credential component class name (e.g. "HuggingFaceCredential").
Returns
- BaseCredential
- An instance of the requested credential component.
get_schema(cls) -> dict
ConfigObjectGenerates the component related Json Schema.
Returns
- dict
- Dictionary representing the Json Schema of the component.
validate(self, ctx: DashAI.back.units.context.ExecutionContext) -> None
BaseUnitCheck preconditions without executing the unit.
Parameters
- ctx : ExecutionContext
- The shared execution context.
validate_and_transform(self, raw_data: dict) -> dict
ConfigObjectIt takes the data given by the user to initialize the model and returns it with all the objects that the model needs to work.
Parameters
- raw_data : dict
- A dictionary with the data provided by the user to initialize the model.
Returns
- dict
- A validated dictionary with the necessary objects.
