class bw2calc.fast_supply_arrays.FastSupplyArraysMixin[source]#

Mixin class for LCA which allows for fast calculations of multiple inventories.

Requires either scikits-umfpack or pypardiso. Must be mixed into an LCA class.

_calculate_pardiso(demands: list[numpy.ndarray]) → numpy.ndarray[source]#
_calculate_umfpack(demands: list[numpy.ndarray]) → numpy.ndarray[source]#
calculate_supply_arrays(demand_arrays: list[numpy.ndarray]) → numpy.ndarray[source]#

Calculate multiple supply arrays in a single calculation.

Much faster than individual calculations, especially when using PARDISO.

Returns a numpy array with dimensions [process scaling amounts, demands]. demands are given in the same order as demand_arrays.

set_chunk_size(chunk_size: int) → None[source]#
chunk_size = 50[source]#
