simpleaudio dependency breaks build with docker

[viac92]

Hi!

I'm trying to run a container with the SDK installed on but every time I tried to achieve this I get this error:

Running setup.py install for simpleaudio: finished with status 'error'
error: subprocess-exited-with-error

× Running setup.py install for simpleaudio did not run successfully.

This is my Dockerfile:

FROM python:3.9-slim

WORKDIR /app

# Copy the requirements file and install dependencies
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

COPY . .

EXPOSE 8765

CMD ["python", "server-script.py"]

I also see that is a common issue for this package:
hamiltron/py-simple-audio#75
hamiltron/py-simple-audio#70
hamiltron/py-simple-audio#62

maybe we should use a more stable and supported package for audio.

In the mean time any suggestions about this error?

Thank you!

I managed to compile the docker image adding gcc and portaudio for compatibility with simpleaudio.

So my Dockerfile is:

FROM python:3.9-slim

# Installa le dipendenze necessarie
RUN apt-get update && apt-get install -y \
    gcc \
    portaudio19-dev

WORKDIR /app

COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

COPY . .

CMD ["python", "server-script.py"]

I used simpleaudio because I thought it would be a simple, low dependency, low hassle solution. Looks like I was wrong. Technically you don’t need simpleaudio unless you’re going to be playing back the audio received from the Frame. It’s only used by the helper function that plays audio.

Does anyone with more Python audio experience have a recommendation for a different package?
