Some GPIO pins don't work. Using python-rpi.gpio

Hi,
I'm following the example "Blink an LED on a GPIO output pin"
in this document: https://up-community.org/wiki/RPi.GPIO

The example uses pin 4 (in the arragement of GPIO.BCM) to control LED.
No problem with that.

But if I changed to pin 27, 22, 23, 24; then the LED won't blink.

If I changed to pin 2, 3, 14; the LED will blink.

Why?
