Exporting and importing database within the same project

[muditchordia]

Hi

I am trying to export database (with activities) and editing flow quantities in excel and importing them back within the same project. When I do that, the system goes into an infinite loop without any results (Writing datasets to SQLite databse). I rename the database in the excel to avoid any naming conflicts.

I notice that in the terminal window i get a message: Can't find migration biosphere-2-3-categories. I am not sure why did would happen as I am still operating within the same project.

Any suggestions on how to deal with this?

Yes we had an error in a previous version which didn't correctly set some Brightway functionality when you would set up a project with that version.

The steps to solve are:

1. Update Activity Browser
2. Start Activity Browser (conda activate ab and then activity-browser)
3. Go to top left, Project > Migrations > Install default migrations
4. Restart your import.

Thanks this helped. I also had to remove the columns “clasifications” and “properties” from the excel for it to work as they have "nan" values.
