I have a code running on a Mac mini M2 that requires torch and torch audio, and that works as expected when testing it in VSCode but when compiling into Docker I get this error, any idea how to fix it? I've found some other posts online regarding the python versions, I did try changing versions (3.10, 3.11) and even using a lower version of torch (1.8.0) but none of that made any difference.
Thank you.

The problem is that you are using the Alpine base image, which is not ideal for installing Torch.
There are a couple of options:
Option 1: Use Debian base image
FROM python:3.9
WORKDIR /code
ADD . .
RUN pip install -r requirements.txt
EXPOSE 80
CMD python app.py
Minimal requirements.txt:
torch==2.0.0
torchaudio==2.0.1
Option 2: Use a PyTorch base image
Here requirements.txt need not include either torch or torchaudio since they are already in the base image.
FROM pytorch/pytorch:2.0.0-cuda11.7-cudnn8-runtime
WORKDIR /code
ADD . .
RUN pip install -r requirements.txt
EXPOSE 80
CMD python app.py
