discrete_optimization.datasets.fetch_data_tsptw(data_home: str | None = None)[source]

discrete_optimization.datasets.fetch_data_weighted_tardiness_single_machine(data_home: str | None = None)[source]

discrete_optimization.datasets.fetch_datasets_from_repo(data_home: str | None = None, dataset_prefixes: list[str] | None = None) → None[source]: Fetch all datasets stored in g-poveda repo.

discrete_optimization.datasets.fetch_fjsp_from_repo(data_home: str | None = None) → None[source]: Fetch fjsp dataset stored in g-poveda repo.

discrete_optimization.datasets.fetch_mis_from_repo(data_home: str | None = None) → None[source]: Fetch mis dataset stored in g-poveda repo.

discrete_optimization.datasets.get_data_home(data_home: str | None = None) → str[source]

Return the path of the discrete-optimization data directory.

This folder is used by some large dataset loaders to avoid downloading the data several times. By default the data dir is set to a folder named ‘discrete_optimization_data’ in the user home folder. Alternatively, it can be set by the ‘DISCRETE_OPTIMIZATION_DATA’ environment variable or programmatically by giving an explicit folder path. The ‘~’ symbol is expanded to the user home folder. If the folder does not already exist, it is automatically created.

Params:: data_home : The path to discrete-optimization data directory. If None, the default path is ~/discrete_optimization_data.
