# use python3.11 on the Alpine Docker Image

Issue Description

Description

I get this error when trying to install Pandas using Python3.11 on the Alpine docker image.

Numpy is supported using version 1.24.1 for Python3.11.

Reproducible example:

• requirements.txt

pandas==1.5.3

• dockerfile

FROM python:alpine
RUN apk update
RUN apk add gcc
RUN pip install -U setuptools pip
COPY requirements.txt .
RUN pip install -r requirements.txt

Run docker command

docker build --tag=test .

Expected Behavior

See Issue Description

Installed Versions

pandas==1.5.3

Thanks for the report! I'm seeing 3.11 support for NumPy in 1.23.3:

https://github.com/numpy/numpy/blob/e47cbb69bebf36007c3ea009aee03e4bfe3b3f3d/setup.py#L115

I'm thinking we should update our setup.cfg to reflect this.

oldest-supported-numpy is saying that the min supported version is 1.23.2 (see https://github.com/scipy/oldest-supported-numpy/blob/b0b3376f6838abd91a9988b936f70939d4acb775/setup.cfg#L65), so it should be fine, I think.

cc @rgommers from numpy for clarification

Comment From: rgommers

There are cp311 wheels for the 1.23.2 release: https://pypi.org/project/numpy/1.23.2/#files. The OP is building on Alpine here, and given that there are no numpy musllinux wheels on PyPI, a build from source is triggered. What we need to see is the full build log with the actual error here. The "may not yet support 3.11" message is only a warning, and not the cause of the failed build.

@carlos-rian - as noted by @rgommers above, the warning you've highlighted isn't an error. Does the log show the error the caused the failure?

Comment From: carlos-rian

@rhshadrach I believe this error is caused when python tries to build the binary for alpine musllinux.

I tried to compile; I added the below lines in the dockefile, and it worked for me.

RUN apk update
RUN apk add \
    build-base \
    freetds-dev \
    g++ \
    gcc \
    tar \
    gfortran \
    gnupg \
    libffi-dev \
    libpng-dev \
    libsasl \
    openblas-dev \
    openssl-dev 

It would be interesting to create the binaries for Alpine; it would be good because the compilations take about 30 minutes. After all, when they fail, the error could be more intuitive.

I created this in a lib that I compiled from rust to python; It's a good idea to use GitHub Actions.
