✓ from pyperplan import search_plan

✗ from pyperplan import search_plan

Load a PDDL domain and problem file, ground the task, and find a plan using the hmax heuristic.

from pyperplan import search_plan from pyperplan.grounding import ground from pyperplan.heuristics import hmax from pyperplan.pddl import parse_domain, parse_problem domain = parse_domain('domain.pddl') problem = parse_problem('problem.pddl') task = ground(domain, problem) plan, _ = search_plan(task, hmax) print('; '.join(plan))

Debug

Known issues

gotchapyperplan only supports STRIPS (no ADL, no negative preconditions, no conditional effects). Using non-STRIPS PDDL will silently produce incorrect grounding.

fix

Ensure your domain and problem files are STRIPS-only.

affects: all

gotchaThe package is no longer actively maintained. The last release (2.1) is from January 2022. Python versions above 3.10 may have compatibility issues with outdated dependencies.

fix
