not able to install packages with requirements.txt in docker-CodePudding

i am creating image with below dockerfile:

FROM python:3.9
WORKDIR /usr/app/
ADD ./requirements.txt /usr/app/requirements.txt
RUN pip install --upgrade pip && \
 hash pip && \
 pip install -r requirements.txt
Add . /usr/app/
ENTRYPOINT ["python"]
CMD ["app.py"]

requirements file:

altair==4.1.0
cmdstanpy==1.0.8
h5py==3.1.0
keras-preprocessing==1.1.2
matplotlib==3.4.2
numpy
opt-einsum==3.3.0
pandas==1.2.4
params-flow
patsy==0.5.3
pmdarima==2.0.2
prophet==1.1.1
pydeck==0.6.2
scikit-learn==0.24.2
scipy==1.6.3
seaborn==0.11.1
statsmodels==0.13.5
streamlit==0.81.1
tensorboard==2.5.0
tensorflow==2.5.0

getting below error:

I removed the packages version, then it tried to download multiple versions and getting timed out.

I have python 3.9 in local system where i am creating requirements.txt using pip freeze > requirements.txt

any suggestions what's going wrong?

CodePudding user response：

Probably the error could be related with pip version. You are using different version of pip in your local system and in Docker image. Make sure you are using the same pip version with your local system.

You can try the following steps:

pip --version in your local system to get the local version (LOCAL_VERSION)
Then update the docker file with the specific version e.g pip install --upgrade pip==LOCAL_VERSION

CodePudding user response：

These 2 constraints seem incompatible:

cmdstanpy 1.0.8 depends on numpy>=1.21
tensorflow 2.5.0 depends on numpy~=1.19.2

If I am not mistaken, ~=1.19.2 means >= 1.19.2, == 1.19.*, so it can not be anything in the in the 1.21 range (nor 1.20, 1.22, and so on) it has to be in 1.19.* but greater than 1.19.2.
