Cannot load brightway2 after clean install: bw2_calc has not attribute...

[Loisel]

After a clean install in a fresh environment via conda install -c romainsacchi premise (conda 4.13.0) I end up with the following error message when trying to load brightway2 as part of the example notebook:

module 'bw2calc' has no attribute 'ComparativeMonteCarlo'

Steps to reproduce:

conda create -n test -c romainsacchi premise -y
conda activate test
python -c "import brightway2"

conda log: log.txt

Hi, try to update bw2calc to the latest release version. You can look it up on pypi.

Hi, thanks for the quick reply (as always). From the github page I'd say the most recent version is 2.0.dev12. This is the version that is also installed by conda (see log.txt in the issue desc).

Installing bw2 directly via

conda create -n bw2 -c conda-forge -c cmutel brightway2

works, however.

Right, so that is the development version. Try instead installing v. 1.8.1 https://pypi.org/project/bw2calc/ https://pypi.org/project/bw2calc/

This works, thanks. It might be worth adding a note to the installation instructions.
