Missing EXIOBASE importer, cannot import Exiobase3MonetaryImporter from bw2io

[nicolnt]

I am trying to make use of Exiobase3MonetaryImporter specified here https://docs.brightway.dev/en/latest/content/api/bw2io/importers/exiobase3_monetary/index.html

But using this code raises an error.

# Brightway packages
import bw2io
import bw2data
# Brightway type hints
from bw2io import Exiobase3MonetaryImporter

Code inspired from official documentation https://docs.brightway.dev/en/latest/content/examples/brightway-examples/data_import/ecoinvent_import.html#imports

Hello there! I will have a look at this next month. Feel free to ping me here if I have not updated the issue by then.

Hi @nicolnt and @michaelweinold

this import should work.

from bw2io.importers.exiobase3_monetary import Exiobase3MonetaryImporter

however, I think #254 is still a problem
