Neopixel not working with Raspberry Pi Pico

Question

My neopixels aren't working when I run them, I am using curcuitpython and using all libraries required

import neopixel
from adafruit_led_animation.animation.solid import Solid
from adafruit_led_animation.color import RED
pixel_pin = board.GP0
pixel_num = 8
pixels = neopixel.NeoPixel(pixel_pin, pixel_num, brightness=0.2, auto_write=False)

I keep getting this in the console

TypeError: function missing required positional argument #3

The same thing happens when I try normal neopixel code

import time
import board
from rainbowio import colorwheel
import neopixel
# Update this to match the number of NeoPixel LEDs connected to your board.
num_pixels = 8
pixels = neopixel.NeoPixel(board.GP0, num_pixels, auto_write=False)
pixels.brightness = 0.5
def rainbow(speed):
 for j in range(255):
 for i in range(num_pixels):
 pixel_index = (i * 256 // num_pixels) + j
 pixels[i] = colorwheel(pixel_index & 255)
 pixels.show()
 time.sleep(speed)
while True:
 rainbow(0)

I would really appreciate if someone could help. PLEASE

• goldilocks: Quick guess -- this: neopixel.NeoPixel(pixel_pin, pixel_num, brightness=0.2, is missing an argument in between pixel_num and brightness=.
• WellActually...: Maybe, I only recently joined the python community and have very little experience with it.
• WellActually...: This is code from the adafruit website and I plan to modify it when it's fixed
• Bravo: which version of circuitpython are you running?
• WellActually...: I am running 7.1.1

Just check that you have the neopixel.py file installed in the lib folder of the circuitpy device, not the neopixel.mpy
