lca_algebraic - 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.importecoinventrelease 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 ! 📧 lca_algebraic@groupes.mines-paristech.fr

lca_algebraic - 1.0.0

1.0.0

Add multi-dataset support, replacing SETUSERDB 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 SETUSERDB()
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.

lca_algebraic - 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 sobolsimplifymodel by removing minor terms of sums
Added support for alternate names for impact methods with the function setcustomimpact_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

lca_algebraic - 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 sobolsimplifymodel 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 incerstochasticdahboard => incerstochasticdashboard
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 sobolsimplifymodel 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
