First add py-numpy, since directly installing with pip doesn't work.
RUN apk add py-numpy
In the next step install it with pip.
RUN python -m pip install numpy

pip install numpy fails ... tries to install it normally. And yet without this step Python gives module not found error. So how do you tell Python that the package was already installed via linux package manager?

I figured out how to make numpy package from Alpine repository to work. Actually py-numpy does not really install bumpy but py3-numpy does.

But even though, py3-numpy installs libraries into /usr/lib/python3.7/site-packagesdirectory but default Python module path does not use it :

$ docker run -it python:3-alpine sh
/ # apk add --update --no-cache py3-numpy
...
/ # python
>>> import numpy
>>> ... module not found ...
>>> import sys
>>> sys.path
['', '/usr/local/lib/python37.zip', '/usr/local/lib/python3.7', '/usr/local/lib/python3.7/lib-dynload', '/usr/local/lib/python3.7/site-packages']

I fixed the problem by settings $PYTHONPATH environment variable to /usr/liblocated site packages :

FROM python:3-alpine

RUN apk add --update --no-cache py3-numpy
ENV PYTHONPATH=/usr/lib/python3.7/site-packages

EDIT: you might also need to install py-numpy-dev to get Numpy C headers required by other Python compiled libraries.

I had various problems on the way starting FROM alpine, FROM python:alpine, but with the following I had a smooth docker build experience:

FROM python:slim
pip install numpy scipy

I assume you can add matplotlib and pandas as extra packages without problems.
See https://pythonspeed.com/articles/alpine-docker-python/ for my choice to start from python:slim.

@sanderzz91 Thanks!

Could anyone help/ advice me with these errors? I would really appreciate it. Thanks in advance.

rendorHaevyn · 2020-08-06T09:37:43Z

Thanks @orenitamar.

@mkdthanga: The following worked for me - I simply used python3-alpine build, and removed python, python-dev and py-pip from the apk command (line 5, OP):

FROM python:3-alpine
WORKDIR /usr/source/app
COPY requirements.txt ./

RUN apk update
RUN echo "http://dl-8.alpinelinux.org/alpine/edge/community" >> /etc/apk/repositories
RUN apk --no-cache --update-cache add gcc gfortran build-base wget freetype-dev libpng-dev openblas-dev
RUN ln -s /usr/include/locale.h /usr/include/xlocale.h
RUN pip install --no-cache-dir -r requirements.txt

Had the same issue... changed the repos from dl-8 to CDN and it worked!

Here's the new Dockerfile

FROM alpine:3.4
RUN echo "http://dl-cdn.alpinelinux.org/alpine/latest-stable/main" > /etc/apk/repositories
RUN echo "http://dl-cdn.alpinelinux.org/alpine/latest-stable/community" >> /etc/apk/repositories

RUN ln -s /usr/include/locale.h /usr/include/xlocale.h
RUN pip install numpy scipy pandas matplotlib

Thanks man your answers solved my problem!

Thanks - this is a great option for my use case

pPanda-beta · 2021-08-18T22:37:57Z

In case you cant move to slim-buster, the natural answer to this is
pip install --extra-index-url https://alpine-wheels.github.io/index ...

samanthahw21 · 2022-01-02T12:46:36Z

Hi, can anyone help. I tried to execute the line in the Docker file but it takes very long to run .
Can anyone can help and what should i do ?
i didn't include panda version in my requirements - i tried but it run error . should i include and what version ? thanks

This leads to ERROR: Failed building wheel for pyarrow for me

PaleNeutron · 2022-07-19T00:56:07Z

@Frikster If you are using python:3-alpine which means you prefer the latest python3.10 version, you could consider using package from alpine instead of from pip.

This way need python package from alpine!!!!

FROM alpine:3.16
RUN apk --no-cache --update-cache add  python3 py3-pip py3-arrow  py3-pandas # and py3-anything package need to be compiled
RUN pip install --no-cache-dir -r requirements.txt
