docker not installing requirements on docker

FROM ubuntu:latest
RUN apt-get update
RUN apt-get install
RUN apt install python3.9 -y
RUN apt-get install -y git
RUN apt-get -y install python3-pip
RUN git clone https://ACCESS_TOKEN#github.com/username/repo
WORKDIR ./appy/
RUN pip install -r requirements.txt
CMD ["python3.9", "main.py"]
Hey, for some reason I'm getings
Traceback (most recent call last):
File "/appy/main.py", line 7, in <module>
import disnake
ModuleNotFoundError: No module named 'disnake'
requirements.txt
disnake=2.4.0
psutil=5.8.0
motor=2.5.1
aiohttp=3.7.4.post0
It appears that the packages in requirements.txt are not being installed properly. Any suggestions to what could be causing this? when building the container there doesn't seem to be any errors.And I can visually see when the container is built that all packages are installed. Including disnake.

Dockerfile returning a non-zero code:1

I'm trying to build an image using DockerFile in AmazonSageMaker but I'm getting the following error.
Traceback (most recent call last):
File "/usr/bin/pip3", line 9, in
from pip import main ImportError: cannot import name 'main' The command '/bin/sh -c pip3 install --upgrade pip setuptools wheel &&
pip3 install mxnet-cu90 --upgrade --pre && pip3 install
keras-mxnet --upgrade --pre' returned a non-zero code: 1
My DockerFile is as below
FROM nvidia/cuda:9.0-runtime
RUN apt-get update && \
apt-get -y install build-essential libopencv-dev libopenblas-dev libjemalloc-dev libgfortran3 \
python-dev python3-dev python3-pip wget curl
COPY train_siamese_network.py /opt/program/train RUN chmod +x /opt/program/train
RUN mkdir /root/.keras COPY keras.json /root/.keras/
RUN pip3 install --upgrade pip setuptools wheel && \
pip3 install mxnet-cu90 --upgrade --pre && \
pip3 install keras-mxnet --upgrade --pre
RUN rm -rf /var/lib/apt/lists/* RUN rm -rf /root/.cache
ENV PYTHONDONTWRITEBYTECODE=1 \
PYTHONUNBUFFERED=1 \
LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/usr/local/lib"
ENV PATH="/opt/program:${PATH}"
WORKDIR /opt/program

you can run a container use image nvidia/cuda:9.0-runtime, try pip install command in the container and see what the command return

failing pjsua python module

I try to use pjsua module for Python on Ubuntu 16.04.
When I try to call AccountConfig, it will return with following error message:
>>> import pjsua
>>> t=pjsua.AccountConfig()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "pjsua.py", line 802, in __init__
self._cvt_from_pjsua(default)
File "pjsua.py", line 859, in _cvt_from_pjsua
for cred in cfg.cred_info:
MemoryError
Compiled pjsip with following:
sudo apt-get install build-essential python-dev libpjsua2
wget http://www.pjsip.org/release/2.7.2/pjproject-2.7.2.tar.bz2
sudo rm -fr pjproject-2.7.2
tar -xf pjproject-2.7.2.tar.bz2 && cd pjproject-2.7.2/
export CFLAGS="$CFLAGS -fPIC"
./configure --enable-shared --disable-sound && make dep && make
cd pjsip-apps/src/python/
sudo python setup.py install
I would appreciate any idea, what am I doing wrong.

Compile with following solved the issue:
sudo apt-get update
sudo apt-get -y install build-essential python-dev libpjsua2 libssl-dev libasound2-dev
wget http://www.pjsip.org/release/2.7.2/pjproject-2.7.2.tar.bz2
tar -xf pjproject-2.7.2.tar.bz2 && cd pjproject-2.7.2/
export CFLAGS="$CFLAGS -fPIC"
./configure && make dep && make
cd pjsip-apps/src/python/
sudo python setup.py install

Python in docker container

I am new to Docker so I am sorry for such an easy question.
I am building a docker container which is built on top of a image which is built on ubuntu:vivid image.
When executing my script within the container I am getting an error:
exec: "python": executable file not found in $PATH
How can I solve this?
When I try to run apt-get install python in my Docker file:
FROM my_image # based on ubuntu:vivid
RUN apt-get update && \
apt-get install -y python3
ENV PATH /:$PATH
COPY file.py /
CMD ["python", "file.py", "-h"]
I get:
WARNING: The following packages cannot be authenticated!
libexpat1 libffi6 libmagic1 libmpdec2 libssl1.0.0 libpython3.4-minimal
mime-support libsqlite3-0 libpython3.4-stdlib python3.4-minimal
python3-minimal python3.4 libpython3-stdlib dh-python python3 file
E: There are problems and -y was used without --force-yes
The command '/bin/sh -c apt-get update && apt-get install -y python3' returned a non-zero code: 100
make: *** [image] Error 1
EDIT: added Dockerfile content

You have similar issue with some Linux distribution: "Why am I getting authentication errors for packages from an Ubuntu repository?"
In all cases, the usual sequence of command to install new packages is:
RUN apt-get update -yq && apt-get install -yqq \
git \
python \
...
The OP Ela reports in the comments:
RUN apt-get update -y && apt-get install -y --force-yes \
git \
python \
...

You are installing python3 and then you use the executable of python, I had the same issue and I have resolved using python3.
Try changing your last line of your Dockerfile :
instead of
CMD ["python", "file.py", "-h"]
try :
CMD ["python3", "file.py", "-h"]
