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 :)
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()
