brightway-lca / brightway-book Goto Github PK

Dear Brightway community,
I am currently investigating the feasibility of importing processes created in SimaPro directly into Brightway. While I have successfully managed to achieve this by manually creating Excel files containing the necessary information required by Brightway (e.g., name, reference product, location), I am curious to explore if there exists an automated method for this task.

Specifically, I am wondering if there is a function or tool within Brightway that facilitates the direct import of processes written in SP and exported in Ecospold v1 format. Despite attempting to follow the same procedure employed for importing the ecoinvent database, I have encountered difficulties in replicating the process.

I would appreciate any guidance or assistance someone could provide in this, I guess you might have encounter the same problems.

Thank you very much!

Souldn't ot be db1 = bd.Database('3D') ?

There are currently 3 different documentation websites (with 3 different logos!):

• https://2.docs.brightway.dev/

Notebooks from Brightway repos (https://github.com/brightway-lca/) can be used. If notebooks from other authors are included in this repo, the respective licenses need to be checked.

...this would allow to use the rudimentary metrics functionality (page visits, etc.).

...there is new and improved documentation on thebe-lite.

34d2de3 added draft of curated list of Brightway training notebooks originally created by @KarinTreyer et al. during the 2022 Brightcon Hackathon on Documentation.

Investigate the use of JupyterLite with either the Pyodide or the XEUS-Python kernel for use with the Jupyter Book site training.brightway.dev.

• Loading Brightway into the browser kernel
• Loading data (eg. subset of Ecoinvent) into the browser kernel

Currently, the third-party package ghp-import is used to automatically build the repository with GitHub Pages. It would be preferrable to use GitHub actions, as per the new documentation by the JupyterBooks team.

The interactive code execution on binder.org servers enabled by the Thebe service is currently timing out. This is likely related to the environment set up in jupyter-book-binder-environment.

Check out their homepage, their collaborative coWASM tool (including their demo). The project was recently featured on HackerNews.

Currently, the text sections in the bw25_for_beginners.ipynb are still written in a weird mix of html and markdown (eg.):

# Introductory note
<a id='section0'></a>

This means we can't use any of the nice functionality that JupyterBook offers.

Thank you for this precious Online Book.
In section 9 of BW25 for Beginners, I have issues running the code I copy below.

I think the problem is that in "brightway2" package there is the attribute "MonteCarloLCA", but I cannot find this attribute in any of the brightway 2.5 packages (bw2data,bw2io,bw2calc,bw2analyzer).
Since I do not want to install brightway2 in the same environment in which I have installed brightway 2.5 (that as I have understood is a good choice, but I am new into brightway so I might be wrong) I was wondering if the attribute MonteCarloLCA is already somewhere also in brightway 2.5 code and I don't find it.

Thank you very much
Giulia

CODE:
#MC simulation with 10 iterations for our banana production and the IPCC GWP100a method
mc = bw.MonteCarloLCA({banana_CO:1}, ('IPCC 2013', 'climate change', 'GWP 100a'))
scores = [next(mc) for _ in range(10)]
scores

Part of the existing notebooks still import packages using as "lazy" import statement

from brightway2 import *

which should be avoided as per PEP690.

Current

There is a section of the book for bw25 where we show how to import EI db using the ecospold single output importer, directly from ecoinvent downloaded files.

Expected

Illustrate also how to import ecoinvent using the ecoinvent_interface package.

In the collected BW2 tutorials, all notebooks either completely skip on the very first first steps of installing python, creating environments and installing packages, or they explain it in a way that is not appropriate for a first-time coder. Often, the reader is referred to external sources, but these are often a bit too generic and their broadness can be overwhelming ("...but what do I need?"). To make the training also accessible to first-time coders, it would be desirable to include clear instructions that also connect to requirements in subsequent notebooks (i.e. instructions to connect to relevant channels, installing required packages etc.).
