Error loading shared library libopenblas.so.3: No such file or directory

[sgr-smile2015]

my dockerfile :

FROM python:3.5-alpine
RUN echo "https://mirror.tuna.tsinghua.edu.cn/alpine/edge/community" >> /etc/apk/repositories
RUN apk add --update --no-cache \
	ca-certificates \	
RUN apk --no-cache  add --virtual .build-deps \
	gcc \
	g++ \
	openblas-dev \
        && ln -s /usr/include/locale.h /usr/include/xlocale.h \
        && pip3 install --no-cache-dir --disable-pip-version-check \
	numpy==1.11.0 \
	pandas==0.18.0 \ 
	scipy==0.13.3 \
	&& apk del .build-deps

in step 2: RUN apk add --update openblas-dev build sucessful,but image have 500MB,
Because alpine does not support dynamic libraries? how can i reduce image size, thank l lot!!

I didn't change much on your Dockerfile, and the resulting image is about 303 MB:

FROM python:3.5-alpine
RUN echo "https://mirror.tuna.tsinghua.edu.cn/alpine/edge/community" >> /etc/apk/repositories
RUN apk add --no-cache \
	ca-certificates \
	openblas

RUN apk add --no-cache --virtual .build-deps \
		gcc \
		g++ \
		openblas-dev \
	&& ln -s /usr/include/locale.h /usr/include/xlocale.h \
	&& pip3 install --no-cache-dir --disable-pip-version-check \
		numpy==1.11.0 \
		pandas==0.18.0 \
		scipy==0.13.3 \
	&& apk del .build-deps

I am getting the same error ImportError: Error loading shared library libopenblas.so.3: No such file or directory (needed by /usr/local/lib/python3.5/site-packages/numpy/core/multiarray.cpython-35m-x86_64-linux-gnu.so)
when running docker-compose up
python packages are installed in /home/user/.local/lib/python3.5/site-packages not in /usr/local/lib but tried by creating the symlink of ~/.local/lib in /usr/local/lib

ubuntu: 16.04
docker-compose: 1.18.0

my dockerfile is like below:

FROM python:3.5-alpine
RUN apk --update add --virtual scipy-runtime python3 py3-pip
&& apk add --virtual scipy-build
build-base python3-dev openblas-dev freetype-dev pkgconfig gfortran
&& ln -s /usr/include/locale.h /usr/include/xlocale.h
&& pip3 install --no-cache-dir numpy
&& pip3 install --no-cache-dir matplotlib
&& pip3 install --no-cache-dir scipy
&& apk del scipy-build
&& apk add --virtual scipy-runtime
freetype libgfortran libgcc libpng libstdc++ musl openblas tcl tk
&& rm -rf /var/cache/apk/*

COPY ./requirements.txt /app/requirements.txt

RUN pip3 --version
&& apk --no-cache --update add --virtual scipy-build

RUN apk --update add --virtual openssh-client

COPY ./webapp /app/webapp
COPY ./midi_match /app/midi_match
COPY ./run.py /app/run.py
COPY ./temp /app/temp
EXPOSE 5000

ENTRYPOINT ["python3"]
CMD ["run.py"]

please suggest something have been stuck for a long time

Because alpine does not support dynamic libraries, i suggest use FROM python:3.5 as base image

[gargayush341]

I have tried the above method but it's saying
/bin/sh: 1: apk: not found
and also If I use FROM python:3.5 as base image this will result in a large size image to reduce the size I used alpine
One more thing the above docker file is working fine on ubuntu 14 but throwing error on 16
