I try to build a docker container with a python script on a raspberry pi.
I' using the arm32v7/python latest image (3.12), but also tried it with 3.9 and 3.10 images.
In my Dockerfile I first update pip and then try to install my requirements. But when it tries to install PyWavelets or scipy it wont move further. I just get "installing build dependencies: still running".
Downloading PyWavelets-1.4.1.tar.gz (4.6 MB)
=> => # 4.6/4.6 MB 11.9 MB/s eta 0:00:00
=> => # Installing build dependencies: started
=> => # Installing build dependencies: still running...
After 30 mins it fails with
� Building wheel for ninja (pyproject.toml) did not run successfully.

I already tried to install them via their apt packages (python3-pywt, python3-scipy) and skip the ones in my requirements.txt, but then I get an error in the installer.
I also tried to use https://www.piwheels.org/simple as index url in my install command but then it wont find any scipy installation candidate.
My Dockerfile:
FROM arm32v7/python
RUN apt-get update && apt-get -y install vim python3-pywt python3-scipy
WORKDIR /app
COPY main.py /app/main.py
COPY requirements.txt /app/requirements.txt
RUN pip install --upgrade pip
#RUN pip install --index-url=https://www.piwheels.org/simple --no-cache-dir -r requirements.txt
RUN pip install -r requirements.txt
