AttributeError: 'ProjectManager' object has no attribute 'migrate_project_25' #177

MMahdi97 commented 3 weeks ago

Hello everyone,

I am trying to use the Activity Browser for a simple model but when I want to calculate the impact I will have this error: bw2data.errors.Brightway2Project: Please useprojects.migrate_project_25before calculating using Brightway 2.5

According to the explanation here: https://github.com/brightway-lca/brightway25 , I understand I need to use this function bw2data.projects.migrate_project_25(), but I don't know where should I write this code!? I tried to use this code in my main code in Premise, but I get this error: image

Could someone please help me with this problem?

Hi @MMahdi97, this should be an issue for the bw2data GitHub repository. I suspect you have BW 2.5 in your environment. However, the databases in your active projects were created using BW 2. So, it's telling you to convert those databases if you want to open them using BW 2.5. However, note that this process is not reversible. Also, note that Activity Browser is not yet compatible with BW 2.5.
