When I run a program to display an image, it errors because it can't find the pillow module which is required to display images.

 #!/usr/bin/env python

import time
from sys import exit

try:
    from PIL import Image
except ImportError:
    exit('This script requires the pillow module\nInstall with: sudo pip install pillow')

import unicornhathd as unicorn

def run(params):
	width, height = unicorn.get_shape()

	img = Image.open('doom.png')

	try:
		while True:
			for o_x in range(int(img.size[0] / width)):
				for o_y in range(int(img.size[1] / height)):

					valid = False
					for x in range(width):
						for y in range(height):
							pixel = img.getpixel(((o_x * width) + y, (o_y * height) + x))
							r, g, b = int(pixel[0]), int(pixel[1]), int(pixel[2])
							if r or g or b:
								valid = True
							unicorn.set_pixel(x, y, r, g, b)

					if valid:
						unicorn.show()
						time.sleep(0.5)

	except KeyboardInterrupt:
		unicorn.off()

That produces a "This script requirtes the pillow module | Install with: sudo pip install pillow" message. Thing is though, pillow is installed.

Running this .py by itself, without Unicorn Remote, works just fine:

#!/usr/bin/env python

import time
from sys import exit

try:
    from PIL import Image
except ImportError:
    exit('This script requires the pillow module\nInstall with: sudo pip install pillow')

import unicornhathd

unicornhathd.rotation(0)
unicornhathd.brightness(0.3)

width, height = unicornhathd.get_shape()

img = Image.open('doom.png')

try:
    while True:
        for o_x in range(int(img.size[0] / width)):
            for o_y in range(int(img.size[1] / height)):

                valid = False
                for x in range(width):
                    for y in range(height):
                        pixel = img.getpixel(((o_x * width) + y, (o_y * height) + x))
                        r, g, b = int(pixel[0]), int(pixel[1]), int(pixel[2])
                        if r or g or b:
                            valid = True
                        unicornhathd.set_pixel(x, y, r, g, b)

                if valid:
                    unicornhathd.show()
                    time.sleep(0.5)

except KeyboardInterrupt:
    unicornhathd.off()

Any ideas?

Can you advise on the best approach to starting unicorn-remote in the background on boot?
My use case is a headless pi set up as an access point.
Thanks

Hi. Can you help with this error on an original unicornhat (8x8). Thanks

I followed your instructions for your unicorn-remote and when running the command to start the program, i get the following error. I did try doing what it suggested with "sudo pip install numpy" but it says it was already installed. Any ideas? Thank you!

sudo pipenv run python run.py

Cool project. It needs to add https://github.com/giampaolo/psutil as a requirement since the CPU update.
👍

Title.

It would be awesome if we could set a program to automatically be started after Unicorn Remote is started.
CPU Utilization, for example. You boot up Unicorn Remote and CPU Utilization is started automatically. Maybe have a folder called "autostart" in which you copy/paste the program you want to start after the remote has been started.

Thank you for your time.
Cheers,

Me again :)
Looking to add more programs to the list.
I've put my .py file in /app/programs/original/
I tried to add it to the the list as per structure in /app/programs/__init__.py but I guess there might be more to it than that?
Sorry for basic question..I'm a tinkerer not a coder, but learning..Thanks!
