Assistance Required with Premise Implementation in Brightway

[nikhilsampathrao]

Dear Romain Sacchi,

I am currently learning to use Premise with Brightway and working on implementing future scenarios. My goal is to update the results back to the Activity Browser for verification. However, I am encountering an error in the process.

Could you please review my code and let me know if I am implementing it correctly? Below is the code I am using:

I would appreciate any guidance or suggestions to resolve this issue.

Thank you for your support.

Best regards,
Nikhil

Hi Nikhil,

I assume you're using premise 1.8.2, based on the cell output from the NewDatabase instance creation.

Please check the method in the NewDatabase class that exports the database to Brightway2. If it exported correctly, you can verify this visually in ActivityBrowser.

In that version, the method should be ndb.write_db_to_brightway()
