TypeError: argument 3 of type 'unit32_t'

I get the following error i run the visualization.py on the raspberry pi: root@xyz:/home/pi/dancyPi-audio-reactive-led-master/python# python visualization.py energy Traceback (most recent call last): File "visualization.py", line 368, in led.update() File "/home/pi/dancyPi-audio-reactive-led-master/python/led.py", line 143, in update _update_pi() File "/home/pi/dancyPi-audio-reactive-led-master/python/led.py", line 107, in _update_pi strip._led_data[i] = rgb[i] File "build/bdist.linux-armv6l/egg/neopixel.py", line 49, in setitem TypeError: in method 'ws2811_led_set', argument 3 of type 'uint32_t'

I am able to run the rpi_ws281x examples and they work just fine....

change line 108: "strip._led_data[i] = rgb[i]" to "strip._led_data[i] = int(rgb[i])" it is passing the numpy int type instead I think

Thanks a lot for your response, now that error is gone: but I still get some error as shown below. The audio play well from the usb audio device and led.py test works fine, but running visualization.py on the raspberry pi gives below error

note: I have changed the file /etc/asound.conf and /usr/share/alsa/alsa.conf: as described here: https://github.com/naztronaut/dancyPi-audio-reactive-led

Any help would be highly appreciated :)

Sounds like this might be an issue with python interfacing with your microphone: https://github.com/Kitt-AI/snowboy/issues/45
