class gluonts.dataset.util.DataLoadingBounds(lower, upper)[source]

Bases: tuple

property lower

Alias for field number 0

Alias for field number 1

class gluonts.dataset.util.MPWorkerInfo[source]

Bases: object

Contains the current worker information.

num_workers = None
classmethod set_worker_info(num_workers: int, worker_id: int)[source]
worker_id = None
worker_process = False
gluonts.dataset.util.dct_reduce(reduce_fn, dcts)[source]

Similar to reduce, but applies reduce_fn to fields of dicts with the same name.

>>> dct_reduce(sum, [{"a": 1}, {"a": 2}])
{'a': 3}
gluonts.dataset.util.find_files(data_dir: pathlib.Path, predicate: Callable[[pathlib.Path], bool] = <function true_predicate>) → List[pathlib.Path][source]
gluonts.dataset.util.get_bounds_for_mp_data_loading(dataset_len: int) → gluonts.dataset.util.DataLoadingBounds[source]

Utility function that returns the bounds for which part of the dataset should be loaded in this worker.

gluonts.dataset.util.to_pandas(instance: dict, freq: str = None) → pandas.core.series.Series[source]

Transform a dictionary into a pandas.Series object, using its “start” and “target” fields.

  • instance – Dictionary containing the time series data.

  • freq – Frequency to use in the pandas.Series index.


Pandas time series object.
