但运行visualization.py时报错如下，原项目也有人提issue，但似乎没人解决。
root@raspberrypi:~/audio-reactive-led-strip/python# python visualization.py
Traceback (most recent call last):
File "visualization.py", line 9, in
import led
File "/root/audio-reactive-led-strip/python/led.py", line 15, in
strip = neopixel.Adafruit_NeoPixel(config.N_PIXELS, config.LED_PIN,
AttributeError: module 'neopixel' has no attribute 'Adafruit_NeoPixel'

查看led.py，确实调用了Adafruit_NeoPixel属性
import neopixel
strip = neopixel.Adafruit_NeoPixel(config.N_PIXELS, config.LED_PIN,
config.LED_FREQ_HZ, config.LED_DMA,
config.LED_INVERT, config.BRIGHTNESS)

不知是哪个lib有问题导致neopixel模块没有Adafruit_NeoPixel属性。
