Unlinked exchanges when importing ecoinvent 3.8 ecospold 2

When I try to import ecoinvent 3.8 in the ecosplod_02 format I get:

19565 datasets 629959 exchanges 1655 unlinked exchanges Type biosphere: 15 unique unlinked exchanges

which is a bit odd as it worked with the same files 3 weeks ago. When importing ecoinvent 3.9 there are no problems.

I have found an open issue for this on github (https://github.com/brightway-lca/brightway2-io/issues/151) but sadly there are no workarounds yet. Until now I have tried using different versions of bw2, bw2io... as well as creating a fresh env but sadly nothing worked so far.

Help would be greatly appreciated :)

Solution

  • Check the readme of the package: https://github.com/brightway-lca/brightway2-io

    For importing ecoinvent 3.8 in a brightway2.5 project, you need bw2io 0.9.dev11.

    pip install bw2io==0.9.dev11

    And you have to use this version as well to setup your project before importing ecoinvent 3.8.

    bw2io.bw2setup()
