From 44ef3ce6ca255467cb9099f8381a365fc1bab9c2 Mon Sep 17 00:00:00 2001 From: Calvin Pieters Date: Thu, 15 Jan 2026 15:05:40 +0200 Subject: [PATCH 1/2] Improve AutoTST dependency handling in job execution Replaces the import-time check for the AutoTST module with a runtime check for the configured AutoTST Python executable, providing a clearer error message if it is missing. Original code was attempting to import AutoTST scripts when in reality we use AutoTST as a subprocess, so it did not make sense to be importing the actual scripts. --- arc/job/adapters/ts/autotst_ts.py | 13 ++++--------- 1 file changed, 4 insertions(+), 9 deletions(-) diff --git a/arc/job/adapters/ts/autotst_ts.py b/arc/job/adapters/ts/autotst_ts.py index bd2aabea0f..6837064bb1 100644 --- a/arc/job/adapters/ts/autotst_ts.py +++ b/arc/job/adapters/ts/autotst_ts.py @@ -19,12 +19,6 @@ from arc.species.converter import xyz_from_data from arc.species.species import ARCSpecies, TSGuess, colliding_atoms -HAS_AUTOTST = True -try: - from autotst.reaction import Reaction as AutoTST_Reaction -except (ImportError, ModuleNotFoundError): - HAS_AUTOTST = False - if TYPE_CHECKING: from arc.level import Level @@ -218,9 +212,10 @@ def execute_incore(self): """ Execute a job incore.
