When running python code:

import spidev import ws2812 spi = spidev.SpiDev() spi.open(0,0)

write 4 WS2812's, with the following colors: red, green, blue, yellow

ws2812.write2812(spi, [[10,0,0], [0,10,0], [0,0,10], [10, 10, 0]])

I get an error on line 2:

Python 3.5.3 (default, Jan 19 2017, 14:11:04) [GCC 6.3.0 20170124] on linux Type "copyright", "credits" or "license()" for more information.

How do I install WS2812 library?

Sorry for the questions. I am a beginner with Raspberry Pi3 and trying to get some Addressable RGB LED's working.

Thank you, Paul
