can't import Amy

[steeley]

I have installed the library as per the readme instructions, and I can use make ./amy-example to compile and hear sound.

I can't run Amy in python- import Amy just says no module found. I'm on Intel MacBook osx Ventura 13.6.9, python 3.12

Try make test

If that works (you see test results) try running python3 and then importing libamy

[steeley]

thanks for the suggestion, but still no go. the test compile runs and produces the result below when run from the terminal.

In the terminal: python3 import amay Amy.drums()

this runs without error but produces no sound.

Also I cannot use the same python3 from within the Thonny editor to import amy. it just says 'module not found'

You need to start the audio:

$ python3 Python 3.12.4 (main, Jun 6 2024, 18:26:44) [Clang 15.0.0 (clang-1500.3.9.4)] on darwin Type "help", "copyright", "credits" or "license" for more information.

import amy amy.live() amy.drums()

If you have anything more than the default speakers attached, you might need:

amy.live(audio_device=1) or some other number.

Thonny IIUC is a front-end for micropython running on device, so its available libraries are unrelated to whatever you can get with python running on your host. It should be possible to get an amy library available on your target micropython device, but we haven't tried that. Instead, Tulip builds as a complete Micropython environment including Amy baked-in.

ok sort off got it working from terminal. I use Thonny with ESP etc and desktop Python stuff and it works well. Shame I can't get it to work with Amy. yes, aware of Tulip.

my goal is to get a DSP/sound/synth DSP lib that works easily on both desktop and embedded stuff.

thanks

We have plans to port AMY and the parts of tulip that interact with AMY to pure micropython for things like thonny. But for now you'll have to DIY or use tulip itself. https://github.com/shorepine/tulipcc/issues/309

Glad you got python AMY going on desktop!

[dpwe]

In my experience with Thonny running on an RP2040, installing a library involved dragging an mpy file onto the device when mounted as a mass storage device, then rebooting, and somehow the micropython on the target device was then able to find it (IIRC).

Figuring out how to compile Amy into such an mpy object file should be pretty easy. But to make it run on some arbitrary target device is more than just linking python functions: To run Amy, there needs to be an audio kernel running all the time as a separate thread, and that kernel needs to know where the audio interface is and how to send samples to it. That sounds like a lot more work, I'm not sure how you'd even get a separate thread running under Thonny/stock MicroPython.

[steeley]

got Thonny running with Amy and desktop Python3 - had to reset some paths. I'm just using the desktop python with amy to generate some automated tones and signals to auto test some audio hardware.

thanks again to all for the suggestions
