Field type modifiers (depending on the type, you can influence behaviour)

For all queries, you can use:
~foo for negation

For string queries, you can use:
^foo to anchor to start of term
foo$ to anchor to end of term
foo*bar for fuzzy matching

For number/date or version queries, you can use:
>foo for values greater than
>=foo for values greater / equal
<foo for values less than
<=foo for values less / equal

Description

Brightway2 calculations

bw2calc appveyor build status Test coverage report

This package provides the calculation engine for the Brightway2 life cycle assessment framework. Online documentation is available, and the source code is hosted on Bitucket.

The emphasis here has been on speed of solving the linear systems, for normal LCA calculations, graph traversal, or Monte Carlo uncertainty analysis.

The Monte Carlo LCA class can do about 30 iterations a second (on a 2011 MacBook Pro). Instead of doing LU factorization, it uses an initial guess and the conjugant gradient squared algorithm.

The multiprocessing Monte Carlo class (ParallelMonteCarlo) can do about 100 iterations a second, using 7 virtual cores. The MultiMonteCarlo class, which does Monte Carlo for many processes (and hence can re-use the factorized technosphere matrix), can do about 500 iterations a second, using 7 virtual cores. Both these algorithms perform best when the initial setup for each worker job is minimized, e.g. by dispatching big chunks.

These instructions assume you have setup the repository first (or read it).

To install/use bw2calc @ version 1.7.7 ...

pip install 'bw2calc==1.7.7'

You can also install the latest version of this package:

pip install --upgrade 'bw2calc'

If necessary, you can specify the repository directly:

pip install \
  --index-url=https://dl.cloudsmith.io/public/demo-docs/awesome-repo/python/simple/ \
  bw2calc==1.7.7

If you've got a project requirements.txt file, you can specify this as a dependency:

--index-url=https://dl.cloudsmith.io/public/demo-docs/awesome-repo/python/simple/
bw2calc==1.7.7

In addition, you can use this repository as an extra index url. However, please read our documentation on this parameter before using it. For example in a requirements.txt file:

--extra-index-url=https://dl.cloudsmith.io/public/demo-docs/awesome-repo/python/simple/
bw2calc==1.7.7
Warning: We highly recommend using pip (or similar) rather than installing directly.
