Getting an error in docker while building an image

[shivamjolly]

Hi, everyone, I am new to docker and as I was building my first image in docker by the following command -

docker build -t money_api .

I got this error:

#9 77.84 Collecting pyarrow; python_version < "3.9" (from streamlit->-r requirements.txt (line 13))

I tried commands to upgrade my pip but nothing happened.

In my requirements file these are the elements-

Flask==1.1.1
gunicorn==19.9.0
itsdangerous==1.1.0
Jinja2==2.10.1
MarkupSafe==1.1.1
Werkzeug==0.15.5
numpy>=1.9.2
scipy>=0.15.1
scikit-learn==0.22.1
matplotlib>=1.4.3
pandas>=0.19
flasgger==0.9.4
streamlit

In my Docker file, I have written -
FROM continuumio/anaconda3:4.4.0
COPY . /usr/app/
EXPOSE 5000
WORKDIR /usr/app/
RUN pip install -r requirements.txt
CMD python flask_api.py

I am working on Windows 10 Pro N, with Python 3.7.

The error you’re encountering is due to an outdated version of Cython. The pyarrow package requires Cython version 0.29 or newer. You also have an outdated version of pip which should be updated.

Here’s what you can do:

Upgrade Cython by adding RUN pip install --upgrade cython before the RUN pip install -r requirements.txt line in your Dockerfile.

Upgrade pip by adding RUN pip install --upgrade pip before installing any packages.

This should resolve the error and allow you to build your Docker image successfully.

may this help yu!
