i installed a self driving car project from superdatascience site , when i open the map using terminal after a while the map window close up or it closes directly after i maximize the map window and it gives me this error :

    [INFO   ] [Base        ] Leaving application in progress...

 IndexError: index 620 is out of bounds for axis 1 with size 600

the code i have in the brain ( ai.py file ) is

    class Dqn():



    def select_action(self, state):

            probs = F.softmax(self.model(Variable(state, volatile = True))*100) # T=100

        action = probs.multinomial(num_samples=1)

            return action.data[0,0]

the code i have in the map ( map.py file ) is

class MyPaintWidget(Widget):



    def on_touch_down(self, touch):

        global length, n_points, last_x, last_y

        with self.canvas:

            Color(0.8,0.7,0)

            d = 10.

            touch.ud['line'] = Line(points = (touch.x, touch.y), width = 10)

            last_x = int(touch.x)

            last_y = int(touch.y)

            n_points = 0

            length = 0

            sand[int(touch.x),int(touch.y)] = 1

what should i do or change ??

One of the values being returned by touch.x or touch.y are bigger than the dimensions of the sand array.

You could try adding a try/except block around it and print a useful message - just as an example, as I have no idea what this programme is doing (in the on_touch_down function):

def on_touch_down(self, touch)

...

...

    try:

        sand[int(touch.x), int(touch.y)] = 1

    except IndexError:

        print("Touchdown did not occur within the end-zone! No goal!")
