PDDL parsing #59

Open bellerifabio opened 7 years ago

bellerifabio commented 7 years ago

I launched the planning system and the knowledge base nodes, providing my PDDL domain and problem. The system says:

`The supplied domain/problem file appear to violate part of the PDDL language specification. Specifically:

The planner will continue, but you may wish to fix your files accordingly.`

I don't understand what's the problem because the specification of the problem is empty; furthermore I used the PDDL files with another planner and it worked. Can you help me please?

We need more information to help you:

Which planner are you using? Are you using POPF as it is default planner of ROSPlan?
What domain and problem files are you using?

Hello,

It could also be that you are intending to use an existing PDDL problem instance, but ROSPlan is generating a new (empty) problem from the knowledge base. If that is the case then you will need to check the launch parameters here: http://kcl-planning.github.io/ROSPlan/documentation/planning_system_launch.html#pa

In particular "generate_default_problem" should be false. Its function is described in the link.
