1.1

🎉 We are glad to release a new version of lca_algebraic : 1.1. 🍾

Main changes :

• Update to latest Brightway 2.4.X (not Brightway25 yet). Which itself enables the use of bw2io.import_ecoinvent_release for easier import of Ecoinvent
• 📚 Added full documentation of the API + example notebook
• Renamed multiLCAAlgebraic to compute_impacts
• Added functional_unit argument to compute_impacts (and other functions) : removing the need to manually build custom activities normalized by the functional units, and making it more flexible.
• Added returns_params argument to compute_impact, to include the values of all parameters in the result, as a tabbed dataframe that can be saved as multisheet Excel file.
• Added support for axis : Flag your activities with custom attributes (by phase, subsystem or whatever) and get the impacts split by those.
• Added computed parameters : Parameters whose default values are Sympy expressions, computed from other parameters. Their values can be overwritten.
• Added linear interpolation of several activities, based on the value of a parameter.
• Improved compatibility with ActivityBrowser : It is now possible to compute impacts / sankey diagrams, etc on a frozen database (=a given scenario of parameters). Full parametric computation of impact in ActivityBrowser works for simple cases only.
• No more conda package. Use pip instead
• Many bug fixes 🐜

👷‍♂️ Next to come .... stay tuned ! :

• Explicit declaration and automatic check of physical units in inventories (using Pint)
• Automatic creation of dynamic web app from a parametric model, (using streamlit)
• Migration to Brightway 2.5.

Also, we now have a dedicated mailing list for updates and discussions. Please register !

1.0.0

1.0.0

• Add multi-dataset support, replacing SET_USER_DB by setBackground(), setForeground()
• Added freezeParams() to freeze parametric dataset for specific scenario to be used by non parametric tools or other foreground datasets.
• Added dataset parameters : parameters scoped to a specific dataset, with scope / conflict resolution of parameters with same names.
• Added extended import / export of datasets with their parameters : export_db(), import_db()
• Added non regression tests

0.0.15

• Added explicit error when cycle is detected in activities.
  This usually means a Bg activity has been imported into User DB :
  lca_algebraic does not support cycles / recursion in User Db,
  since those are developped as litteral formulas.
• Added support for several background databases.
  User Db is guessed or can be specified using SET_USER_DB()
• Support coproducts in graphtraversal.
  See [PR #9] by @ntropy-esa
• Add support for loading / saving parameters into Brightway DB, with compatibility with Brightway2 and Activity Browser.
  See functions loadParams() and persistParams(). See also issue #8.
• Added new function exploreImpacts(), like printAct() but showing impact of each exchange.

0.0.14

0.0.14

• Internal change for generated webapp
• Add several display options to graphs()
• Fix overlapping graph bug

0.0.13

• Fixed bug in param extract_activities of multiLCAAlgebric

0.0.12

• Added a step of simplification of models in sobol_simplify_model by removing minor terms of sums
• Added support for alternate names for impact methods with the function set_custom_impact_labels
• Added parameter extract_activities to multiLCAAlgebric in order to compute contribution of a subset of activities to the global impact

0.0.11

Added BETA distribution type. See online doc

0.0.10

Fixed issue #4 : Added back handling of default params

0.0.9

0.0.9

• Removed cache for find{Bio/Tech}Act, in order to lower memory usage.
  Instead, we now use core Brightway capabilities for searching activities.
• Added function sobol_simplify_model for generating simplified models,
  and compare_simplified for comparing their distributions with the initial model.

0.0.8

Cleanup dependencies

0.0.7

• Added parameters 'var_params' for all stats tools, for providing list of parameters to vary.
  Other parameters will be set at their default value.
• Fixed typo in the function name incer_stochastic_dahboard => incer_stochastic_dashboard
• Fixed bug of int overload : convert everything to float

0.0.6

• Rename modelToExpr() to simplifiedModel()
• Improve performance of computation. Added multithread computation for LCA and Sobol.
• Added method sobol_simplify_model that computes list of most meaningful parameters,
  based on Sobol analysis, and then generates simplified models based on it.

0.0.5

• Add function modelToExpr(model, impacts), returning expression with background activities replaced
  by the value of each impact.

0.0.4

• Added button for exporting data as csv on any Dataframe in stats tools
• actToExpression now replaces fixed params by their default values, providing simplified models.
• newSwitchAct can take custom amounts (not only '1') by providing tuple (act, amount)

0.0.3

First released version

0.0.3

Finalize conda & pip packaging
