Installing numpy, scipy, pandas and matplotlib in Alpine (Docker)

Dockerfile

# Below are the dependencies required for installing the common combination of numpy, scipy, pandas and matplotlib 
# in an Alpine based Docker image.
FROM alpine:3.4
RUN echo "http://dl-8.alpinelinux.org/alpine/edge/community" >> /etc/apk/repositories
RUN apk --no-cache --update-cache add gcc gfortran python python-dev py-pip build-base wget freetype-dev libpng-dev openblas-dev
RUN ln -s /usr/include/locale.h /usr/include/xlocale.h
RUN pip install numpy scipy pandas matplotlib

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

I'm getting

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 apk --no-cache --update-cache add gcc gfortran python python-dev py-pip build-base wget freetype-dev libpng-dev openblas-dev
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!

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.

Thanks - this is a great option for my use case

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 ...

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

Pull a pre-built alpine docker image with nginx and python3 installed

FROM tiangolo/uwsgi-nginx-flask:python3.6-alpine3.7
ENV LISTEN_PORT=8000
EXPOSE 8000
COPY /app /app
RUN echo "http://dl-8.alpinelinux.org/alpine/edge/community" >> /etc/apk/repositories
RUN apk --no-cache --update-cache add gcc gfortran python python-dev py-pip build-base wget freetype-dev libpng-dev openblas-dev
RUN ln -s /usr/include/locale.h /usr/include/xlocale.h
RUN pip install pandas

Thanks @orenitamar.

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

@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
