构建 docker 映像时无法安装 sklearn

Question

When I try to install sklearn (scikit-learn) when building a docker image, it fails.

These are the processed lines of the Dockerfile:

FROM amancevice/pandas:0.25.0-alpine

RUN apk update
RUN apk add build-base
RUN apk add gcc musl-dev libc-dev util-linux-dev linux-headers python3-dev postgresql-libs postgresql-dev git libffi-dev libmemcached-dev zlib-dev ca-certificates zlib-dev jpeg-dev freetype-dev libpng

RUN pip3 install --upgrade pip
RUN pip3 install scikit-learn

Everything goes smoothly, right until the last line. There, it first of all takes forever, then an error occurs. This is the log:

Step 6/13 : RUN pip3 install scikit-learn

The command '/bin/sh -c pip3 install scikit-learn' returned a non-zero code: 1

Answer 1

Try to downgrade your Python version, because Scikit Learn don't support Python 3.9 yet.

Answer 2

I have the same problem. This guy was using python 3.7 and I'm using 3.8 Python Version should not be the problem here.

Try to use other Docker image such as slim ones.

FROM python:3.8-slim
...
