I have created my own image containing my project in an ubuntu system. I was able to successfully build the image. No error showed up build-time. However, at run-time, a python import error is thrown up. The package is "requests". I have tried running a separate install statement from Dockerfile. I have also tried just including it in requirements.txt. But both return the same error. What is the fix to this?
ModuleNotFoundError: No module named 'requests'
Dockerfile:

I need to have a Dockerfile with Python3 and the latest version of OpenCV. The Dockerfile I have written is described below:
FROM ubuntu
#Install OpenCV
RUN apt-get update &&\
apt-get install -y cmake
RUN apt-get install -y gcc g++
RUN apt-get install -y python3-dev python3-numpy
# To support GUI features
RUN apt-get install -y libavcodec-dev libavformat-dev libswscale-dev
# To support GTK 2
RUN apt-get install -y libgtk2.0-dev
# To support GTK 3
RUN apt-get install -y libgtk-3-dev
#Optional dependencies
RUN apt-get install -y libpng-dev
RUN apt-get install -y libjpeg-dev
RUN apt-get install -y libopenexr-dev
RUN apt-get install -y libtiff-dev
RUN apt-get install -y libwebp-dev
# Clone OpenCV repo
RUN apt-get install -y git
RUN git clone https://github.com/opencv/opencv.git
#Compile
RUN mkdir /opencv/build && \
cd /opencv/build
RUN cmake ..
RUN make
However, when i run it, it gives me the following error with cmake.
Step 17/27 : RUN cmake ..
---> Running in 3dca32df2036
CMake Error: The source directory "/" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.
The command '/bin/sh -c cmake ..' returned a non-zero code: 1
Do you know what am i doing wrong?
You just need to chain the last RUN instructions:
#Compile
RUN mkdir /opencv/build && \
cd /opencv/build && \
cmake .. && \
make
Explanation:
A RUN statement creates a new image layer and executes the specified shell command. This means that each RUN statement will run the command in a separate shell, so the current directory from the previous RUN will not be preserved (you can see that the CMake current directory is / by looking closely at the error message).
You can find more info about RUN statement in the Docker documentation and I also recommend reading Best practices for writing Dockerfiles.
This question already exists:
Docker - install node as part of the ubuntu image
Closed 2 years ago.
I want to be able to set up an image that has both the Ubuntu and the node images.
I started with the Ubuntu and downloaded all the necessary programs, including node.js.
Here is the latest Dockerfile i created, out of the many i tried:
FROM ubuntu
RUN DEBIAN_FRONTEND=noninteractive apt-get update
RUN DEBIAN_FRONTEND=noninteractive apt-get install -y software-properties-common
#install freecad
RUN add-apt-repository ppa:freecad-maintainers/freecad-daily
RUN DEBIAN_FRONTEND=noninteractive apt-get update
RUN DEBIAN_FRONTEND=noninteractive apt-get install -y freecad-daily
#install utils
RUN DEBIAN_FRONTEND=noninteractive apt install -y git
RUN apt install -y python3-distutils
#install node
RUN DEBIAN_FRONTEND=noninteractive apt-get install -y git-core curl build-essential openssl libssl-dev \
&& git clone https://github.com/nodejs/node.git \
&& cd node \
&& ./configure \
&& make \
&& sudo make install
COPY . .
RUN npm install
CMD ["node","server.js"]
Can i use two different FROM commands, for building my image?
The one to download ubuntu, and the other to download node.js?
I am having issues with installing python3 with yum in dockerfile. I did look on internet, I did try few things, not working. Its just small thing but not able to figure it out. When I try to build below docker file I do get error . I get error at line -
RUN yum install -y oracle-epel-release-el7
There are no enabled repos.
Run "yum repolist all" to see the repos you have.
You can enable repos with yum-config-manager --enable <repo>
The docker file is below.

# Install Python 3.6
RUN yum install -y oracle-epel-release-el7
RUN yum install -y python36
# Install AWS CLI
RUN pip3 install awscli
CMD ["/bin/bash"]
Why mix apt and yum? You're already using apt-get, just use it to install your python too:
apt-get install python3.6
I want to create a docker image with specifically python 3.5 on a specific base image which is the nvidia/cuda (9.0-base image) the latter has no python environment.
The reason I need specific versions is to support running cuda10.0 python3.5 and a gcc version<7 to compile the driver all together on the same box
When I try and build the docker environments (see below) I always end up with the system update files which load python3.6
The first version I run (below) runs a system update dependencies which installs python 3.6 I have tried many variants to avoid this but always end up 3.6 in the final image.
Any suggestions for getting this running with python3.5 are welcome
Thanks
FROM nvidia/cuda
RUN apt-get update && apt-get install -y libsm6 libxext6 libxrender-dev python3.5 python3-pip
COPY . /app
WORKDIR /app
RUN pip3 install -r requirements.txt
ENTRYPOINT [ "python3" ]
CMD [ "app.py" ]
Another variant (below) I have tried is with virtualenv and here again I can't seem to force a python 3.5 environment
FROM nvidia/cuda
RUN apt-get update && apt-get install -y --no-install-recommends libsm6 libxext6 libxrender-dev python3.5 python3-pip python3-virtualenv
ENV VIRTUAL_ENV=/opt/venv
RUN python3 -m virtualenv --python=/usr/bin/python3 $VIRTUAL_ENV
ENV PATH="$VIRTUAL_ENV/bin:$PATH"
COPY . /app
WORKDIR /app
RUN pip3 install -r requirements.txt
ENTRYPOINT [ "python3" ]
CMD [ "app.py" ]
You can try using conda. I used several stages to minimize final container and to speedup/cache local builds.
# first stage
FROM nvidia/cuda:11.1-base-ubuntu18.04 as builder
RUN apt-get update && apt-get install -y curl wget gcc build-essential
# install conda
RUN wget --quiet https://repo.anaconda.com/miniconda/Miniconda3-4.5.12-Linux-x86_64.sh -O ~/miniconda.sh && \
/bin/bash ~/miniconda.sh -b -p /opt/conda
# create env with python 3.5
RUN /opt/conda/bin/conda create -y -n myenv python=3.5
# install requirements
WORKDIR /app
COPY requirements.txt /app
ENV PATH=/opt/conda/envs/myenv/bin:$PATH
RUN pip install -r requirements.txt
RUN pip uninstall -y pip
####################
# second stage (note: FROM container must be the same as builder)
FROM nvidia/cuda:11.1-base-ubuntu18.04 as runner
# copy environment data including python
COPY --from=builder /opt/conda/envs/myenv/bin /opt/conda/envs/myenv/bin
COPY --from=builder /opt/conda/envs/myenv/lib /opt/conda/envs/myenv/lib
# do some env settings

ENV LC_ALL=C.UTF-8
ENV LANG=C.UTF-8

WORKDIR /app
COPY ./run.py /app
CMD [ "python", "run.py"]
You can install from PPA and use it as usual:
FROM nvidia/cuda
RUN apt-get update && apt-get install -y --no-install-recommends software-properties-common \
libsm6 libxext6 libxrender-dev curl \
&& rm -rf /var/lib/apt/lists/*
RUN echo "**** Installing Python ****" && \
add-apt-repository ppa:deadsnakes/ppa && \
apt-get install -y build-essential python3.5 python3.5-dev python3-pip && \
curl -O https://bootstrap.pypa.io/get-pip.py && \
python3.5 get-pip.py && \
rm -rf /var/lib/apt/lists/*
COPY requirements.txt requirements.txt
RUN pip3.5 install -r requirements.txt
CMD ["python3.5", "app.py"]
Hi everyone I am trying to build numpy from source in docker container.
This is my Dockerfile:
FROM debian:testing
MAINTAINER Dr Suman Khanal <suman81765#gmail.com>
LABEL updated_at '2017-07-26'
WORKDIR /
RUN apt-get update \
&& apt-get install -y gnupg git wget build-essential python3 python3-dev
python3-setuptools python3-pip libatlas3-base libatlas-dev libatlas-base-dev
liblapack-dev libblas-common libblas3 libblas-dev cython
RUN git clone https://github.com/numpy/numpy.git
WORKDIR /numpy
RUN python3 setup.py build --fcompiler=gnu95 install
CMD ["numpy"]
But its throwing this error.
Build failed: The command '/bin/sh -c python3 setup.py build --fcompiler=gnu95 install' returned a non-zero code: 1
Any help?
Many thanks,
Suman

RUN pip3 install nose

I tested it with success build and run:
$ docker run -it test-numpy
.......
----------------------------------------------------------------------
Ran 7 tests in 0.004s
OK
Also I dont know exactly what you want to achieve with CMD ["numpy"] because it's directory. I added install nose b/c it is required for numpy's test.
You can test and play with numpy in docker:
docker exec -it test-numpy bash
