Control.py broken?

[ZimneJonas]

I seem to have problems with control.py.
I expect to have done some mistake while installing.

1. This is an Error i get for running something like 'ctl.ground([("step",[42])])' in the python API:

File "/home/zimne/anaconda3/envs/tel/lib/python3.9/site-packages/clingo/control.py", line 335, in ground
c_part.params[i] = sym._rep
AttributeError: 'int' object has no attribute '_rep'

2. And this is an error if I am running the Asprilo Visualizer:

File "/home/zimne/anaconda3/envs/tel/lib/python3.9/site-packages/visualizer-0.2.2-py3.7.egg/visualizer/parser.py", line 206, in parse
AttributeError: 'Control' object has no attribute 'builder'

*The same programs do run on 5.4 though

I think the API interface has slightly changed in the latest update. Wrap the 42 inside Clingo.Number().-------- Originalnachricht --------Betreff: Re: [potassco/clingo] Control.py broken?

Thank you, that works.
If you look at the "How to build your own ASP-based system ?!" section 4 (pp.24-27). Schaub/Romero et. al.
https://www.cs.uni-potsdam.de/wv/publications/DBLP_journals/corr/abs-2008-06692.pdf
The examples do not run either on 5.5.1 nor 5.4 as far as I tested (for different reasons).
5.5.1 has the the different Control class.
5.4 has no accessible Aplication class

Making the new clingo versions not backwards compatible, seems bad for educational papers like this.
As well as for programs like the asprilo visualizer.

However, if this is necessary it is no longer a problem.

Hi @ZimneJonas ! Thanks for pointing this out to us! In fact, the paper at archive will ultimately align with 5.5 (have you checked the recent version ?), once it is published. We just pre-published its preliminary version that only ran with an intermediate version. Sorry for any inconvenience!

I am going to open an issue for the asprilo visualizer.

Hi, I tried to run the examples published in 'Multi-shot ASP solving with clingo' section 5.1, Listing 5, 6 and 7 https://arxiv.org/abs/1705.09811 and encountered the same error as Jonas. I followed the advice to wrap the parameters inside the number method and now I'm getting :
File "/home/niko/anaconda3/lib/python3.9/site-packages/clingo/symbol.py", line 248, in Number
_lib.clingo_symbol_create_number(number, p_rep)
TypeError: an integer is required
Did I make a mistake or is there also an updated version for this paper?

Please do not comment on long closed issues and rather use a new one. Please open a new one and also show us the code you are trying to run.
