Jetson Nano - Developer Kit Library Access

[CatzCatzCatzCatz]

Hello there,

I’m working with a a group to program a jetson nano on a per-designed robot sold as “Jetbot”.
I don’t understand why a script ran in CLI works fine but then I try the same script in Jupyterlab and it fails, the same applies for scripts written in Jupyterlab and later tried in CLI. It’s also the same error which indicates the library isn’t there but how does one see it but not the other? Are they accessing different directories? If so is there a way to change this?

Example code below of one that works fine from CLI but not from the lab. The error indicates it doesn’t recognize the GPIO library.

#GPIO Library
#include <JetsonGPIO.h>
import Jetson.GPIO as GPIO
import time

#Pin Definition
trigPin = 11
echoPin = 12

#Setup GPIO Channel
GPIO.setmode(GPIO.BOARD);
GPIO.setwarnings(False);
GPIO.setup(trigPin,GPIO.OUT);
GPIO.setup(echoPin,GPIO.IN);

GPIO.output(trigPin,False)
time.sleep(2)

try:

    while True:

            GPIO.output(trigPin, True)
            time.sleep(1.0)
            GPIO.output(trigPin, False)

            while GPIO.input(echoPin)==0:
                    pulse_start = time.time()

            while GPIO.input(echoPin)==1:
                    pulse_end = time.time()

            pulse_duration = pulse_end - pulse_start


            distance = pulse_duration * 17150

            print ("Distance: ", distance,"cm")
