I’m trying to install ecoinvent 11 via brightway25, here’s my code: from bw2data.parameters import ActivityParameter, DatabaseParameter, ProjectParameter, Group import bw2data as bd import bw2io as bi -> bd.projects.set_current(“Test”) -> bi.import_ecoinvent_release(“3.11”, “apos”, “username”, “password”). But I get the error message: please install ecoinvent_interface to use this function. What can I do to fix this or how can I install this function?

I copied an activity for electricity in ecoinvent and changed this activity and replaced it with more up-to-date data, now I want to replace the old activity in the entire ecoinvent database with my new one, how can I do this?

I want to duplicate the entire ecoinvent database in my brightway2.5 program, how can I do this? not just copy one activity, but copy the entire ecoinvent database -> all activities at once

Now I’m using Brightway2 and Activity browser on my MacBook Pro(M1 silicon). I built my own parameterized database with Ecoinvent-3.8 (apos). I found that the LCA results(score) are different via these two ways. Using Brightway2, I got 82439873.99596766, while in Activity Browser I got 65659359.41451239. Since I’ve already built the same model in Simapro, I think the smaller one(from Activity Browser) is better, though both are larger than that in simapro.

Importing a IO table in Brightway2.5 with IOTableBackend.

In Brightway2.5, I am having difficulties understanding the relation between datapackages and databases. Here I see examples where either a bw database is created or a bw datapackage. This is the only example I find where both are used, but the bw database is created first, and how they are coupled is unclear.

In brightway2 I am trying to understand how to use the IOTableBackend.write method

In a Brightway2 project, I would like to import several activities (e.g. production of a gas), for which I only have aggregated LCIA results according to the LCIA method CML. I therefore have data on their environmental impacts in the CML categories, but do not know the LCI data. The mentioned activities are again inputs of other activities in the project (e.g. the gas is used in another process). In the end I would like to analyse the LCIA results of different activities using the CML method. Does anyone know how I can best import the activities for which I only know the cumulative LCIA results (and not the LCI data) so that I can use them in the further calculations?
