Error when installing Prophet in docker image


I am trying to install prophet, yet (only when trying to docker build by image) the following error is thrown:

The above issue does not appear on my local execution. I have installed prophet using the pip install prophet command and everything works properly. The issue arises only when trying to create the Docker image.

The Dockerfile I use is the following:

FROM ubuntu:18.04
RUN apt-get update
# To avoid the questions related to the geographic area
RUN ln -snf /usr/share/zoneinfo/$CONTAINER_TIMEZONE /etc/localtime && echo $CONTAINER_TIMEZONE > /etc/timezone

RUN apt-get install -y python3.10 python3-pip
RUN pip3 install flask pandas numpy cython
RUN python3 -m pip install prophet

COPY app.py app.py
COPY checks.py checks.py
COPY predict.py predict.py

EXPOSE 5000

CMD ["python3", "-u", "app.py"]

I've tried also to install ujson and then try to install prophet. The ujson is installed yet afterwards the same issue arises.


Solution

  • The error because you're using an old version of the import of __future__ annotations as shown here https://peps.python.org/pep-0563/#enabling-the-future-behavior-in-python-3-7.

    Since you're using Python10, try to upgrade pip, so your Dockerfile becomes:

    FROM ubuntu:18.04
    ...
    RUN apt-get install -y python3.10 python3-pip
    RUN pip3 install --upgrade pip
    RUN pip3 install flask pandas numpy cython prophet
    ...
