Problems with Scenario Difference File

[YuKa90]

Hi there,

I'm completely new to this, so hopefully it's not a noob question and at the right place.

I'm using
Activity-Browser: 2.10.3
bw2data: 3.6.6
bw2io: 1.8.2
bw2calc: 0.8.12
ecoinvent: 3.10 consequential

Problem 1: Each time I'm trying to create a superstructure, I get following error:

Created database: test_sup_ssp1-ndc_30_60
09:15:38 | ERROR | AttributeError: 'ABSignals' object has no attribute 'databases_changed'
Traceback (most recent call last):
  File "D:\Anaconda\envs\ab\Lib\site-packages\ab_plugin_scenariolink\layouts\tabs\right.py", line 76, in generate_database
    ab_signals.databases_changed.emit()
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'ABSignals' object has no attribute 'databases_changed'

I tried to cancel activity-browser and restarted it. The Scenario Difference File was created, but another error occured when I tried to use it with a simply test-dataset. (Since the CSV-file was created using comma as a seperator, I used chose comma as separator in AB).

Problem 2:

11:36:42 | INFO | Loading Scenario file. This may take a while for large files
11:36:45 | ERROR | SyntaxError: invalid syntax (<unknown>, line 0)

I would be thankful, if someone could help me.

I also face exactly same problem with you!

[romainsacchi]

Hi @YuKa90 @BaristaShaun do you confirm you have ab-plugin-scenariolink==0.1.2?

[YuKa90]

@romainsacchi , thanks for taking on this problem so fast. From my side I can confirm 0.1.2 . If you need further details/data, please let know. This superstructure approach is such an amazing and helpful tool

[romainsacchi]

Hi @marc-vdm, did not we fix the AttributeError: 'ABSignals' object has no attribute 'databases_changed' issue?

[romainsacchi]

As far as I know, the first issue does not prevent the completion of the process. This means the database, and the SDF are produced anyway, despite AB freezing. So you should see the database in the database list.

[romainsacchi]

Regarding Issue #2, I'm not sure. But could you try loading it anyway with ";" as a separator?

[BaristaShaun]

@romainsacchi
Hi!
I have 0.1.2 version and I also try it with ";" as a separator.
But it has this error.

[YuKa90]

@romainsacchi Hi! I have 0.1.2 version and I also try it with ";" as a separator. But it has this error.

same here

[YuKa90]

Problem #1: yes, database seems to be created and is accessible in AB

[romainsacchi]

@YuKa90 Any chance you could send me the SDF somehow? My email address is r_s at me.com

This is resolved in the next version of scenariolink. The other problems related to Activity Browser, so I will close this

[YuKa90]

@romainsacchi I sent you a link via WeTransfer, since the file was to large so send vie email

[romainsacchi]

@YuKa90 @BaristaShaun, I have uploaded a new version of ab-plugin-scenariolink, which hopefully fixes your issues.
Could you update it (conda update ab-plugin-scenariolink)?

After the update, conda list should give you:

ab-plugin-scenariolink   0.1.4
activity-browser   2.10.3 
unfold   2024-11-27 or 1.2.2

Can you then try again the database creation process?

[YuKa90]

@romainsacchi, thanks for keeping this alive. I tried after all mentioned packages were updated to the versions above:

• The SDF was generated and exported
• When writing the superstructure-database, following errer occured

Writing superstructure database... 11:47:28 | ERROR | Failed to unfold database: Exchange links to non-existent activity: {'amount': 1.0, 'categories': None, 'input': (' test_11_28_sup_rem_ssp1_ndc_50_60', 'ab7d8cb4310a4ed58148f897dcaf173f'), 'location': 'RoW', 'name': 'formaldehyde production, methanol oxidation', 'product': 'formaldehyde', 'type': 'production', 'unit': 'kilogram'}

[romainsacchi]

@YuKa90 ok, can you try to click here

and try again?

[YuKa90]

@romainsacchi woohoo, so far it's working! props to you , this saved me a lot of work, I'm happy :))
