Error when loading scenario files

[OliverLyon]

Updating AB

• Yes, I have updated AB and still experience this issue

What happened?

Hi,

Today when I tried to do a scenario LCA I received this error when I try to load the scenario files: SyntaxError: invalid syntax. I pasted the error below from the terminal.
Anyone know how to solve this issue.
Thank you

Oliver

This is a screen shot inside the superstructure file output by scenario link

Now I tried with another laptop for a newly built environment and installations then started another project, the problem presist.

@OliverLyon do you think you can try to migrate to AB3? It should probably work there. Unfortunately, scenarioLink is not available there... but if you create the superstructure in AB2 and then migrate the project to bw2.5 (from within the AB) it should work. I suggest you only migrate a copy of your project as the migration from bw2 to bw2.5 is a one-way direction.

Hi, @bsteubing
Thank you for your reply. For the migration of project, can I do it directly in AB3? Since I created the project in AB2 (not in Brightway).

Hi, @bsteubing, I tried to load the scenario files to AB3 and the same issue persist. I tried with the superstructure I created from last year with the same scenarios and it works. But all the superstructure created recently can not be loaded.

[OliverLyon]

@bsteubing the error might be that in the superstructure database file there are a number of rows that are missing the "to key" values in the generated superstructure file generated by scenario link. An empty to key becomes '', and ast.literal_eval('') raises:
SyntaxError: invalid syntax (, line 0)
Is there any way to solve this issue?

[bsteubing]

@OliverLyon could you try two things please:

• run a normal LCA calculation on your superstructure database (not in scenario mode)
• delete the rows where keys are missing from the scenario file and see if that runs? (you can also try to run it with just the first 5 rows or so) - it sounds like the issue is in your scenario file;

Also, how did you create the superstructure database and scenario file? Did you use premise for that? Or scenariolink?

Hi, @bsteubing, I created the superstructure and scenario files from scenario link. So it could be a problem of this plugin. I found the "to key" section of "formaldehyde production, methanol oxidation" and "hydrocarbons purification, molecular sieve separation of naphtha" are missing (54 rows in total, I did not try all scenarios but for SSP1,2,5 PKGUDG1150 they all missed 54 rows for "to key"), compared to the file generated by scenario last year (which works). So I filled them back manually, then it works.
So yes, it should be a problem of scenariolink, but I have not check if the superstructure database missed these two flows as well.
I hope it is a easy bug to fix.
