GPU install failing at tornado module

[Keith Chester]

While running the command
docker build -t floydhub/dl-docker:gpu -f Dockerfile.gpu . within the repos, it fails during the installation of the tornado module in python. Below is the relevant stack trace.

Collecting tornado>=4.0 (from ipykernel)
  Downloading tornado-5.0.tar.gz (504kB)
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

      File "/tmp/pip-build-dS1ilp/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).
    
    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-dS1ilp/tornado/
The command '/bin/sh -c 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' returned a non-zero code: 1

Unsure where to go from here. Thanks!

I encountered the same problem.

same :(

Same issue with pywbem pip package. The python2 code in this package uses M2Crypto as ssl package for historical reasons and python 2.7.6 is still the required system python package for at least Ubuntu 14.04.

Same problem for me. Joining this thread to monitor for solution.

Same problem, joining the thread.

I just resolved this issue by upgrading my python 2.7 to 2.7.10.
Try running the following commands from you virtual environment:
pyenv install 2.7.10
pyenv global 2.7.10

@ptiagi That's a great fix if the issue was inside a virtual environment. would need to install virtualenv and along with it pyenv. As things are now an other fix would be to grab python from https://python.org and install it.

Popping the following into my Dockerfile.gpu overcame the up-to-date SSL module issue.

ARG PYTHON_BASEDEPS="build-essential python-pip"
ARG PYTHON_BUILDDEPS="libbz2-dev \
   libc6-dev \
   libgdbm-dev \
   libncursesw5-dev \
   libreadline-gplv2-dev \
   libsqlite3-dev \
   libssl-dev \
   tk-dev"


ARG PYTHON_TARFILE="Python-2.7.9.tgz"
ARG PYTHON_TARHOST="https://www.python.org/ftp/python/2.7.9"
ARG PYTHON_SRCDIR="Python-2.7.9"

RUN apt-get update
RUN apt-get install -y ${PYTHON_BASEDEPS} ${PYTHON_BUILDDEPS}

RUN wget "${PYTHON_TARHOST}/${PYTHON_TARFILE}"
RUN tar xvf ${PYTHON_TARFILE}
 
RUN cd ${PYTHON_SRCDIR} && \
   ./configure && \
   make && \
   make install

Same problem after resolving #86 on Ubuntu 16, but #84 (comment) worked.
