Couldn't build the floydhub/dl-docker:gpu image

[abdallah197]

when running
docker build -t floydhub/dl-docker:gpu -f Dockerfile.gpu .
the output in the terminal is :

i am running docker-ce, my nvidia driver is 390.48 and installed nvidia-docker2

I ended with the same problem, I can expose the solution I found but please consider this as a workaround done by a newbie.

The main problem is pip found an already installed ipython and it is unable to uninstall it before upgrading it.

You need to modify the Dockerbuild.gpu file.

Previous lines on the file:

# Install other useful Python packages using pip
RUN pip --no-cache-dir install --upgrade ipython && \
	pip --no-cache-dir install \
		Cython \
		ipykernel \
		jupyter \
		path.py \
		Pillow \
		pygments \
		six \
		sphinx \
		wheel \
		zmq \
		&& \
	python -m ipykernel.kernelspec

Fix:

RUN apt-get -y remove ipython
RUN pip --no-cache-dir install --upgrade ipython

RUN     pip --no-cache-dir install \
                Cython \
                ipykernel \
                jupyter \
                path.py \
                Pillow \
                pygments \
                six \
                sphinx \
                wheel \
                zmq \
                && \
        python -m ipykernel.kernelspec

As I said, this is a non tested workaround, I am not completely conscious about the possible consequences. Possibly, the wise decision here is to wait until someone with more experience offers a smarter solution.

@jose-goncabel that actually solved some of the errors
right now the errors in the terminal are:

matplotlib 1.3.1 requires tornado, which is not installed.

and

File "/tmp/pip-install-Ea9g31/tornado/setup.py", line 146, in <module>
        raise ImportError("Tornado requires an up-to-date SSL module. This means "
    ImportError: Tornado requires an up-to-date SSL module. This means Python 2.7.9+ or 3.4+ (although some distributions have backported the necessary changes to older versions).

Try this it worked for me.

# Install useful Python packages using apt-get to avoid version incompatibilities with Tensorflow binary
# especially numpy, scipy, skimage and sklearn (see https://github.com/tensorflow/tensorflow/issues/2034)
RUN apt-get update && apt-get install -y \
		python-numpy \
		python-scipy \
		python-nose \
		python-h5py \
		python-skimage \
		python-pandas \
		python-sklearn \
		python-sympy \
		&& \
	apt-get clean && \
	apt-get autoremove && \
	rm -rf /var/lib/apt/lists/*


RUN pip install matplotlib
RUN pip install ipython

Will commit and ask to merge

The solution shown here worked for me:

[hyzhak]

got the same issue on regular Docker in Ubuntu:

Found existing installation: ipython 1.2.1
Cannot uninstall 'ipython'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

RUN pip install matplotlib
RUN pip install ipython

@Spottybadrabbit , Thank you very much for this wonderful address!
But I don't understand why you need to put those two pip install in a separated layers. This operation would only add the image's complexity.

I'd suggest to replace by:

RUN pip install matplotlib / 
              ipython

This seems still open, right?
