GPIO.setmode() not working? Why?

Does the Jetson module library work at all?
In the examples you can only find the imported RPi library (import RPi.GPIO as GPIO), but no import Jetson.GPIO as GPIO

Try with GPIO.BOARD

# GPIO library
import Jetson.GPIO as GPIO

# define Pins
LED4 = 7
LED8 = 12
LED3 = 13
IN3 = 15
LED7 = 18
IN2 = 19
IN1 = 21
IN7 = 22
LED2 = 23
IN6 = 24
LED1 = 29
IN5 = 32
IN4 = 33
LED5 = 35
LED6 = 38
IN8 = 40

# Pin Definition
LED_IN = [IN1,IN2,IN3,IN4,IN5,IN6,IN7,IN8]

# Warning disable
#GPIO.setwarnings(False)

# Set up the GPIO channel
GPIO.setmode(GPIO.BOARD)
GPIO.setup(LED_IN, GPIO.OUT, initial=GPIO.LOW) 
 
# ON the LEDs
for led_pin in LED_IN:
	GPIO.output(led_pin, GPIO.HIGH)
	GPIO.cleanup()
print("all LED are ON")

hello a.phoenix,

here’s should be a bug in your for loop.
please revise the code as following for each of your GPIOs in the LED_IN.
for example,

for led_pin in range(len(LED_IN)) :
    GPIO.output(LED_IN[led_pin], GPIO.HIGH)

hello a.phoenix,

please do debug your python code to check whether the pin number has assign correctly.
how about assign the GPIO number directly through APIs, i.e. GPIO.output(<#>, GPIO.HIGH)
