Is OpenCL enabled or disabled in the digiKam settings under Miscellaneous -> System? Can you disable it (restart digiKam) and test whether it no longer crashes? Maik
(In reply to Maik Qualmann from comment #1) > Is OpenCL enabled or disabled in the digiKam settings under Miscellaneous -> > System? Can you disable it (restart digiKam) and test whether it no longer > crashes? Yes, OpenCL was enabled. After disabling it, digiKam no longer crashes, and the retraining works as exptected until it is complete.
