LCI instead of unit process data imports of 3.2 causes huge CPU/memory issues #36

Closed aleksandra-kim closed 4 years ago

Original report by Niko Heeren (Bitbucket: nheeren, GitHub: nheeren).

When I try to do data = bw2.Database("ecoinvent 3.2 cutoff").load() my Mac is busy loading data for ages. I killed the process after it used 40+GB of RAM (!).

Is that the documentation that is contained in ecoinvent 3.2 now? Probably it would be smart to offer a way to load the database without the documentation.

Resolution is probably to make the correct choice of ecoinvent files much clearer in the documentation.

This is sufficiently explained in documentation for now.
