unable to install Gensim with Python 3.5 on ubuntu

I am running a dockerfile on a ubuntu base image as follows :
FROM ubuntu:14.04
# Install dependencies
RUN apt-get update
RUN apt-get install -y \
software-properties-common
RUN add-apt-repository universe
RUN apt-get install -y python3.5 \

RUN apt-get update
RUN apt-get upgrade
#RUN apt-get install google-cloud-sdk

RUN pip3 install glob3
RUN pip3 install --upgrade pip
#RUN pip3 install pandas
RUN pip3 install glob3
#RUN pip3 install json
RUN pip3 install numpy
RUN pip3 install fuzzywuzzy
RUN pip3 install gensim
I have python 3.5 installed on this machine, but still I am getting the error as follows :

Is there some specific version of Gensim that i need to download or this is some different error.

use python:3.5:
FROM python:3.5
RUN pip install gensim glob3 ....
that will save you a lot of space and steps ....
If you want to still using ubuntu:14.04 then you need to use this:
apt-get install -y python-dev && python3.5 -m pip install gensim
since python3.4 is the default on the image

I tried the solutions provided by Python does not see pygraphviz, but it doesn't work.

sudo apt-get install python-dev graphviz libgraphviz-dev pkg-config
or the following might be needed if you're using Python 3:
sudo apt-get install python3-dev graphviz libgraphviz-dev pkg-config
then
pip install pygraphviz

For MacOS, I needed to do:
$ brew install graphviz
$ sudo pip install pygraphviz

For fedora users:
yum list available graphviz*
select the appropriate package for your Fedora distribution
sudo yum install 'graphviz-devel.x86_64'
pip install pygraphviz

On macOS, I made it with,
$ brew install graphviz
$ sudo pip install pygraphviz

For CentOS.
As graphviz-devel is required to fix this issue, you will need to install it with yum. To do this you are required to add repo's where package is available. In my case Atomic repos worked fine.
wget -q -O - http://www.atomicorp.com/installers/atomic | sh
This will add atomic repos, then
sudo yum install graphviz-devel
And you should be able to perform
pip install pygraphviz

I ran into this problem when creating a Dockerfile for Django with a python-alpine image.
I was able to solve it thanks to this post adding the package "graphviz-dev" along with the rest of my app's dependencies.
Example:
#Install dependencies
RUN apk add --update --no-cache --virtual .build-deps \
build-base \
alpine-sdk \
postgresql-dev \
libffi-dev \
python3-dev \
libffi-dev \
jpeg-dev \
zlib-dev \
musl-dev \
libpq \
graphviz-dev \
&& pip install --no-cache-dir -r /code/requirements_dev.txt \
&& find /usr/local \
\( -type d -a -name test -o -name tests \) \
-o \( -type f -a -name '*.pyc' -o -name '*.pyo' \) \
-exec rm -rf '{}' +

Error when installing using pip

Not sure whats going on here but I am getting an error every time I try to install something using pip I get the following error:
Command "/usr/bin/python -c "import setuptools, tokenize;__file__='/private/var/folders/b0/5843zgyj1yz3b8q2l7wrtj8h0000gn/T/pip-build-V4hy8S/PySocks/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /var/folders/b0/5843zgyj1yz3b8q2l7wrtj8h0000gn/T/pip-bIOl7C-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /private/var/folders/b0/5843zgyj1yz3b8q2l7wrtj8h0000gn/T/pip-build-V4hy8S/PySocks

Try
sudo pip install -U setuptools
If this doesn't solve your problem then
Firstly, you need the python-dev package because Pillow needs compile headers defined.
sudo apt-get install python-dev
On Ubuntu 14.04 you need few extra packages to get pillow working. Install all of them with the command:
sudo apt-get install libtiff5-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk

Seems that your PiP can't access Setuptools as per the "import setuptools" in the error. Try the below first then try running your pip install again.
sudo pip install -U setuptools
Solution from Github Issue

Launch the command prompt with 'run as administrator' rights before installing.
then try the script -
pip install package_name_here
if error is thrown,then import setup tools
pip install -U setuptools
if again error thrown then upgrade your pip installer using this script(personally worked for me)
python -m pip install --upgrade pip

I had the same problem on Windows Git Bash but installing setuptools did not fix it. Then I noticed another error message further up:
building 'twisted.test.raiser' extension error: Microsoft Visual C++ 14.0 is
required. Get it with "Microsoft Visual C++ Build Tools":
http://landinghub.visualstudio.com/visual-cpp-build-tools
That link was dead but ultimately this page had a link to the correct download: https://wiki.python.org/moin/WindowsCompilers
I installed Microsoft Build Tools for Visual Studio 2017 and that resolved it.

It majorly depends on the type of packages you suppose to install.
Frequently its failing due to the missing of
libsasl2-dev a package for authentication abstraction library which use in the Ubuntu version
First, install:
sudo apt-get install libsasl2-dev
then run:
pip install <<\package_name>>

first run as superuser:
sudo su
then :
pip install PyOpenGL PyOpenGL_accelerate

If you get this error on Windows, like I did, then just run the command-line tool (cmd.exe or Powershell) as Administrator and try again.

Error installing pip package on debian / python 3.4

I have python 3.4 compiled from sources on my debian 7.8.
I have already installed some Python packages using pip and virtualenv (django, pillow etc), but i have an error installing python-phonenumbers (https://github.com/daviddrysdale/python-phonenumbers).
I tried it using virtualenv and without, running pip3 install phonenumbers and manually downloading archive and running python3 setup.py install. Every time I get same error:
Command "/usr/local/bin/python3.4 -c "import setuptools, tokenize;
__file__='/tmp/pip-build-ogsbxm_d/phonenumbers/setup.py';
exec(compile(getattr(tokenize, 'open', open)(__file__)
.read().replace('\r\n', '\n'), __file__, 'exec'))"
install --record /tmp/pip-98gunm55-record/install-record.txt
--single-version-externally-managed --compile"
failed with error code -9 in /tmp/pip-build-ogsbxm_d/phonenumbers
I tried it on my windows and ubuntu 14.04 - everything ok. How can i fix it?

For Ubuntu 14.04, from Docker image python:3.4.3-slim this combination worked for me:
sudo apt-get update
sudo apt-get install -y build-essential
sudo apt-get install -y python3.4-dev
sudo apt-get install -y libpq-dev
pip3 install psycopg2
Note build-essential package. It was crucial in my case. Maybe it will help you too.

How to install the library netifaces for Python3 in Ubuntu 12.04?

I made a program in Python3 which uses the package netifaces, I installed it with pip3 in two computers which had Ubuntu 13.04 and Ubuntu 13.10. However, I need to install it in other computer which has Ubuntu 12.04, and here I cannot install pip3 (python3-pip) because it is not on the repositories.
What I did was the next steps:
sudo aptitude install python3-setuptools
sudo easy_install3 pip
And then I had pip3 available. The problem is when I tried to install netifaces with pip3, which gives me next error:
error: command 'gcc' failed with exit status 1
Command /usr/bin/python3 -c "import setuptools, tokenize;__file__='/tmp/pip_build_root/netifaces/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-gkaftl-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /tmp/pip_build_root/netifaces
Storing debug log for failure in /home/anubia/.pip/pip.log
If I install netifaces with pip or aptitude or apt-get the program does not recognise the library, because its documents are installed in python2 folders. I even tried to do a symbolic link from python3 folders to them, but it did not work.
Any ideas, please?

Solved!
I had to install the package python3-dev too, then the installation of netifaces from pip3 did not give me an error and now I can use it.
So the whole process (in my case) was:
sudo aptitude install python3-setuptools
sudo easy_install3 pip
sudo aptitude install python3-dev
sudo pip3 install netifaces
