i'm using Google Cloud Vision API to detect a captured image taken from pi camera and if the picture detected as an animal, it will delete the picture and if it's not, it will running another function called: takePicture(image_name). My script works absolutely well, but most times i have a weird problem called Segmentation Fault and when this happened it doesn't interrupt my python program but my 4x4 keypad (connected to RPi) stop working and also automatically create another loop process of python program which is still running even with "keyboard interrupt".

def detectImage(self, image_name):
        path = '/home/pi/homesecurity/pictures/' + image_name
        max_results=1
        with open(path, 'rb') as image_file:
            content = image_file.read()
        image = vision.types.Image(content=content)
        objects = client.object_localization(image=image,max_results=max_results).localized_object_annotations
        for object_ in objects:
           if (object_.name == 'Animal' or object_.name == 'Cat' or object_.name == 'Dog' or object_.name == 'Bird' or object_.name == 'Insect'):
             print ('False Alarm: This is an animal!')
             os.remove('/home/pi/homesecurity/pictures/' + image_name) #Deletes the taken picture.
             print 'File', image_name, 'has beeen deleted'
             break
           else:
             Process(target=interact().takePicture(image_name)).start()
             print('Not an animal!')

Is it possible of the old hardware ? because i'm using Raspberry Pi Model B and python 2.7

Segmentation Faults happen when your python program tries to use memory that is out of reach. Meaning it doesn't have the resources requested.

Check out this answer and try to find out at what point that is happening. I think it might be due to the low computational power your raspberry pi is providing. Maybe you can allocate more with this.
