SEVERE ERROR

[Rafael Martinez]

Hi there.

I'm forced to use Learnlib 0.13.0 version, and therefore bound to Autoamtalib 0.7.0 (right?)

I could print graphs with earlier versions, but with Automatalib 0.7.0 I get the next error:

Sep 27, 2018 6:40:18 PM net.automatalib.visualization.DummyVP visualize

SEVERE: Attempted to visualize graph with 1 nodes, but no usable visualization provider configured

Almost the same message when I run examples package under automatalib branch 0.7.0

Could you show me an example program to print graphs with 0.7.0 ?

Thanks!

Hi Rafael,


the error sounds like, you are missing a visualization implementation on your classpath. Normally, these should be picked up automatically, if available. (If both -- the JUNG and DOT visualizers -- are available, the DOT one is preferred, but even this can be configured).

Are you using maven or the standalone distribution jar? If you are using maven, it should simply suffice to specify the proper dependency (see [0] for reference).


Kind regards,
Markus
