Hallo wieder,
ich habe einen Bug entdeckt. Erstmal funktioniert das .hdf5 Datei Hochladen gut. Hier ist ein normales Ergebnis vom Terminal:

Ich habe da zwei Bilder hinzugefügt und das Programm hat geklappt. Ich habe das Programm beendet und dann habe ich Programm etwa fünf mal mehr laufen lassen (also Bilder in den Ordner tun, und testen, ob ich noch Bilder sehen kann und dann das Programm beendet). Aber dann nach etwa fünf Mal funktioniert das Programm nicht mehr. Jetzt bekomme ich das gleiche, jedes mal, das ich das Programm laufen lasse und neue Bilder hinzufüge:

try to connect to event service ...
Also es geht nicht mehr in die while-Schleife uzw. Weißt jemand woran es liegen kann. Vielleicht muss ich genau den Thread schließen? Oder vielleicht ist es wohl das Problem wie __blackjack__ erwähnt hat?
Hier ist der Code bzgl. dieses Problemes:

print('try to connect to event service ...')
worker = watchdog_search.Worker("/home/test_image_analyzer_files/Test_Data/")

thread.started.connect(worker.work)
thread.start()
worker.new_file.connect(self.on_finished_run)
