Changelog

[0.6] - 2024-11-01

  • New array mapping implementation using sparse matrices which is ~100x faster and allows for very large input values

[0.5] - 2024-08-20

  • Default is now 64 bit integers for indexing; compatible with bw_processing 1.0

[0.4.3] - 2024-06-04

  • Allow MappedMatrixDict to take extra kwargs for compatiblity with custom matrix classes

[0.4.2] - 2024-06-04

  • Fix diagonal MappedMatrixDict - col_mapper is not required
  • Unroll tuples when multiplying SparseMatrixDict
  • Switch from fs to fsspec (following bw_processing)

[0.4.1] - 2023-12-18

  • Allow passing MappedMatrix subclass to MappedMatrixDict

[0.4] - 2023-12-07

  • Add SparseMatrixDict
  • Defined matrix multiplication for MappedMatrixDict

[0.3] - 2023-10-25

  • Add MappedMatrixDict class for MultiLCA

[0.2.5] - 2022-05-21

  • Add functions to reset indexers directly and on MappedMatrix

[0.2.4] - 2022-05-15

  • Avoid StopIteration errors on empty combinatorial filtered datapackages

[0.2.3] - 2022-02-02

  • Fix an error where the previous attribute current_data was not consistently changed to data_current

[0.2.2] - 2021-11-26

  • Fix an error raised when a ResourceGroup was empty after masking

[0.2.1] - 2021-11-26

  • Add input_provenance function on showing from which datapackage and resource group data comes from

[0.2] - 2021-11-25

Added attributes in MappedMatrix for sensitivity analysis

Added the following attributes to MappedMatrix:

  • input_data_vector: The stacked data vector from all resource groups.
  • input_row_col_indices: The stacked indices structured array (with columns row and col) from all resource groups.
  • input_indexer_vector: A vector of values from the resource group indexers. This array flattens value from combinatorial indexers, be careful that you understand the values.
  • input_uncertainties: The stacked distributions structured array (dtype bw_processing.UNCERTAINTY_DTYPE) from all resource groups. See the documentation for how this works with arrays and interfaces.

Note that these values are before any aggregation policies are applied, i.e. values to be placed in the same matrix cell are not summed or overwritten.

Changed attributes in ResourceGroup

Rewrote basic functionality of ResourceGroup to make it clear what data was masked and was wasn't. Removed raw_indices, indices, raw_flip, row, col, and data. We now use a uniform naming convention for data, row, and col:

  • data_original: The data as it is present in the datapackage, before masking.
  • data_current: The data sample used (before aggregation) to build the matrix. It is both masked and flipped.
  • row|col_mapped: Mapped row and column indices. Has the same length as the datapackage resource, but uses -1 for values which weren't mapped.
  • row|col_masked: The data after the custom filter and mapping mask have been applied.
  • row|col_matrix: Row and column indices (but not data) for insertion into the matrix. These indices are after aggregation within the resource group (if any).

flip is always masked. current_data is now data_current (to be consistent with the naming convention), and is both masked and flipped, but not aggregated.

.indices are removed, use .get_indices_data().

[0.1.4] - 2021-10-20

  • Add transpose flag when creating matrices

[0.1.3] - 2021-06-16

  • Allow array data with use_distrbutions (instead of raising an error)

[0.1.2] - 2021-06-15

  • Fix bug in boolean logic order of operations in has_relevant_data

[0.1.1] - 2021-06-02

  • Add custom_filter argument to filter out some package data based on indices values.
  • Add indexer_override argument for custom indexers.
  • Respect existing indexers on datapackages.
  • filter_groups_for_packages as a separate utility function instead of in DataPackage class.
  • Allow creation of (0,0) matrices if no data arrays are present.

[0.1] - 2021-05-19

First complete public release.
