issue getting it to fully work

[ChaseA4280]

I got everything installed but it says failed after running visualization.py and it also is either really laggy and or its just not hearing the music at all so any advice would help thank you

Which Pi are you using and are you supplying enough power? And if you can share the output that says failed, that would be helpful.

im using RPi 3B+ and im plugged into the wall so i would assume power is fine and another question would the version of scipy pip and numpy and all the other installs matter as I kinda restarted and am doing everything by hand to see whats going wrong and the sudo pip3 install numpy scipy==1.4.1 pyaudio pyqtgraph line wont work the preparing metadata (pyproject.toml) part errors and when i did get the lights to turn on this pops up (linked image) https://mail.google.com/mail/u/0?ui=2&ik=038fe8bdf7&attid=0.1&permmsgid=msg-a:r1051267117548864159&th=18492e20b2d621e1&view=fimg&fur=ip&sz=s0-l75-ft&attbid=ANGjdJ9JIW4dUqBKkBOiu-hvjtjsqWXfL0UdustKUzB1nudPR6idUZXYUSk25jCdcLatAVq9S8y4z2-cyZoc9VO1qpJPPjze5RDSrtbzJ0ACBJ-cR997uk_z-S_as30&disp=emb&realattid=18492e1f0144cce3e671

to be honest after messing with it for a bit i think it may be power related any suggestions with that?

[naztronaut]

You should try to use at least a 3 amp power source. Even if you're plugged into the wall, you should check the power adapter you're using and see what the "output" is. Depending on how many LEDs your strip has, I'd say 2 amp is the minimum you should do but I'd recommend 3 amps.

[ChaseA4280]

ok sounds goog im using a 2.5 amps source with 300 leds so would that not be enough
and i got the lights on again but its just flickering so based off that do you think power is my problem?

[naztronaut]

I think you do need more power for 300 LEDs. And you should check the connections too, make sure nothing is loose.

If you're powering the lights through the PI, the other thing you can do is provide power to the LEDs separately and let the Pi just do the processing. It will put less strain on the Pi that way.

how would i go about doing that?

[ChaseA4280]

what would be my best option as I am doing this as a school project i would like to get this done as fast as possible in the easiest way possible

[ChaseA4280]

I fixed it and here are my recommendations to anyone else trying this project

1. before running install.py go though and download scipy numpy and all of those things seperatly using commands like sudo apt-get install python3-scipy sense scipy doesnt like to install right in the install.py
2. write a code and implement it in to the dancipi file that is called on.py and follow the instructions located here => https://www.thegeekpub.com/16187/controlling-ws2812b-leds-with-a-raspberry-pi/
3. run the visualization after running on.py
4. sudo pip3 install rpi_ws281x adafruit-circuitpython-neopixel this installation also seemed to help for me
