bw2calc.utils.extract_uncertainty_fields(array)[source]#: Extract the core set of fields needed for uncertainty analysis from a parameter array

bw2calc.utils.get_seed(seed=None)[source]#: Get valid Numpy random seed value

bw2calc.utils.load_arrays(objs)[source]#

Load the numpy arrays from list of objects objs.

Currently accepts str filepaths, BytesIO,: numpy.ndarray arrays. Creates copies of objects

bw2calc.utils.load_calculation_package(fp)[source]#

Load a calculation package created by save_calculation_package.

NumPy arrays are saved to a temporary directory, and file paths are adjusted.

fp is the absolute file path of a calculation package file.

Returns a dictionary suitable for passing to an LCA object, e.g. LCA(**load_calculation_package(fp)).

bw2calc.utils.md5(filepath, blocksize=65536)[source]#: Generate MD5 hash for file at filepath

bw2calc.utils.wrap_functional_unit(dct)[source]#

Transform functional units for effective logging.

Turns Activity objects into their keys.
