在 docker 版本中安装 pip 后系统挂起

Question

I am running the following Dockerfile

FROM python:3.6.9
WORKDIR /app
COPY . /app

# install dependencies
RUN pip3 install tensorflow==1.15
RUN pip3 install -r requirements.txt

# define the port number
EXPOSE 5000

# run
CMD ["python3", "./index.py"]

I am trying to build an image of an ML model deployed on a Flask application. When I run the command my system hangs.

sudo docker build -t lhp .

I have to restart the system to rerun docker. The build execution stops at RUN pip3 install tensorflow==1.15 . I have tried this multiple times using pip and pip3 but the error persists. I have also tried replacing tensorflow with other python packages. The problem seems to be with pip and not with the particular python package. Please help me solve this. Following is a copy of my terminal.

aishwarya@aishwarya-ThinkPad-W540:/media/aishwarya/2E068D88068D522F/lhp$ sudo docker build -t lhpoc8 .

Step 4/7 : RUN pip3 install tensorflow==1.15

That's it. This is where it stops.

Update

Here is the image history

Answer 1

install pip first (in this order in your dockerfile)

RUN pip install -U pip

then run pip install (ex. for python3)

RUN python3 -m pip install --no-cache-dir -r requirements.txt

Answer 2

So basically nothing worked. I was facing the error due to some symlinks because I had shifted my Docker storage to another disk. I uninstalled Docker and then eventually, Ubuntu. Increased my Ubuntu partition size till it was big enough to store docker images. Reinstalled Ubuntu, Docker. Now I live in peace with happy and successful docker builds.
