It is possible to install NumPy with pip using pip install numpy.
Is there a similar possibility with SciPy? (Doing pip install scipy does not work.)
Update
The package SciPy is now available to be installed with pip!
Prerequisite:
sudo apt-get install build-essential gfortran libatlas-base-dev python-pip python-dev
sudo pip install --upgrade pip
Actual packages:
sudo pip install numpy
sudo pip install scipy
Optional packages:
sudo pip install matplotlib OR sudo apt-get install python-matplotlib
sudo pip install -U scikit-learn
sudo pip install pandas
src
An attempt to easy_install indicates a problem with their listing in the Python Package Index, which pip searches.
easy_install scipy

All is not lost, however; pip can install from Subversion (SVN), Git, Mercurial, and Bazaar repositories. SciPy uses SVN:
pip install svn+http://svn.scipy.org/svn/scipy/trunk/#egg=scipy
Update (12-2012):
pip install git+https://github.com/scipy/scipy.git
Since NumPy is a dependency, it should be installed as well.
In Ubuntu 10.04 (Lucid), I could successfully pip install scipy (within a virtualenv) after installing some of its dependencies, in particular:
$ sudo apt-get install libamd2.2.0 libblas3gf libc6 libgcc1 libgfortran3 liblapack3gf libumfpack5.4.0 libstdc++6 build-essential gfortran libatlas-sse2-dev python-all-dev
To install scipy on windows follow these instructions:-
Step-1 : Press this link http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy to download a scipy .whl file (e.g. scipy-0.17.0-cp34-none-win_amd64.whl).
Step-2: Go to the directory where that download file is there from the command prompt (cd folder-name ).
Step-3: Run this command:
pip install scipy-0.17.0-cp27-none-win_amd64.whl
I tried all the above and nothing worked for me. This solved all my problems:
pip install -U numpy
pip install -U scipy
Note that the -U option to pip install requests that the package be upgraded. Without it, if the package is already installed pip will inform you of this and exit without doing anything.
If I first install BLAS, LAPACK and GCC Fortran as system packages (I'm using Arch Linux), I can get SciPy installed with:
pip install scipy
On Fedora, this works:
sudo yum install -y python-pip
sudo yum install -y lapack lapack-devel blas blas-devel
sudo yum install -y blas-static lapack-static
sudo pip install numpy
sudo pip install scipy
If you get any public key errors while downloading, add --nogpgcheck as parameter to yum, for example:
yum --nogpgcheck install blas-devel
On Fedora 23 onwards, use dnf instead of yum.
For the Arch Linux users:
pip install --user scipy prerequisites the following Arch packages to be installed:
gcc-fortran
blas
lapack
Addon for Ubuntu (Ubuntu 10.04 LTS (Lucid Lynx)):
The repository moved, but a
pip install -e git+http://github.com/scipy/scipy/#egg=scipy
failed for me... With the following steps, it finally worked out (as root in a virtual environment, where python3 is a link to Python 3.2.2):
install the Ubuntu dependencies (see elaichi), clone NumPy and SciPy:
git clone git://github.com/scipy/scipy.git scipy
git clone git://github.com/numpy/numpy.git numpy
Build NumPy (within the numpy folder):
python3 setup.py build --fcompiler=gnu95
Install SciPy (within the scipy folder):
python3 setup.py install
In my case, it wasn't working until I also installed the following package : libatlas-base-dev, gfortran
sudo apt-get install libatlas-base-dev gfortran
Then run pip install scipy
install python-3.4.4
scipy-0.15.1-win32-superpack-python3.4
apply the following commend doc
py -m pip install --upgrade pip
py -m pip install numpy
py -m pip install matplotlib
py -m pip install scipy
py -m pip install scikit-learn
The answer is yes, there is.
First you can easily install numpy use commands:
pip install numpy
Then you should install mkl, which is required by Scipy, and you can download it here
After download the file_name.whl you install it
C:\Users\****\Desktop\a> pip install mkl_service-1.1.2-cp35-cp35m-win32.whl
Processing c:\users\****\desktop\a\mkl_service-1.1.2-cp35-cp35m-win32.whl
Installing collected packages: mkl-service
Successfully installed mkl-service-1.1.2
Then at the same website you can download scipy-0.18.1-cp35-cp35m-win32.whl
Note:You should download the file_name.whl according to you python version, if you python version is 32bit python3.5 you should download this one, and the "win32" is about your python version, not your operating system version.
Then install file_name.whl like this:
C:\Users\****\Desktop\a>pip install scipy-0.18.1-cp35-cp35m-win32.whl
Processing c:\users\****\desktop\a\scipy-0.18.1-cp35-cp35m-win32.whl
Installing collected packages: scipy
Successfully installed scipy-0.18.1
Then there is only one more thing to do: comment out a specfic line or there will be error messages when you imput command "import scipy".
So comment out this line
from numpy._distributor_init import NUMPY_MKL # requires numpy+mkl
in this file: your_own_path\lib\site-packages\scipy__init__.py
Then you can use SciPy :)
Here tells you more about the last step.
Here is a similar anwser to a similar question.
Besides all of these answers,
If you install python of 32bit on your 64bit machine, you have to download scipy of 32-bit irrespective of your machine.
http://www.lfd.uci.edu/~gohlke/pythonlibs/
In the above URL you can download the packages and command is: pip install
For gentoo, it's in the main repository:
emerge --ask scipy
You can also use this in windows with python 3.6 python -m pip install scipy

I'm trying to install h5py, but when I do pip install h5py or use python setup.py install from the source code, fatal error:
hdf5.h: No such file or directory.
Other posts mention to do pip install libhdf5-dev or pip install libhdf5-serial-dev to resolve this, but it says "no matching distribution found."
How can I install h5py? I am ssh'd into an Odyssey computer using the CentOS 6.5 version of the Linux. Also, I do not have sudo privileges. Thanks!
Your error is because you are missing the hdf5.h header, pip will not install the development headers, you need to install them using your package manager, on Centos it would be:
yum install hdf5-devel
If you look at the installation instrcutions:
Source installation on Linux and OS X
You need, via apt-get, yum or Homebrew:
Python 2.6, 2.7, 3.3, or 3.4 with development headers (python-dev or similar)
HDF5 1.8.4 or newer, shared library version with development headers (libhdf5-dev or similar)
NumPy 1.6.1 or later
This link helped:
https://github.com/Homebrew/legacy-homebrew/issues/23144
I installed LinuxHomeBrew and did:
brew tap homebrew/science
brew install hdf5
pip install h5py
I was able to install h5py!
sudo apt-get update
sudo apt-get install python-h5py
(Source)
Also, not pip install libhdf5-dev or pip install libhdf5-serial-dev, but apt install libhdf5-dev and apt install libhdf5-serial-dev.
Then, run pip install h5py
Running the below fixed my problem as I had an error related to xlocale.h
sudo ln -s /usr/include/locale.h /usr/include/xlocale.h
I have built python from scratch and it now sits in a folder in my home directory. I am unsure of how to install libraries for this particular version/location.
Ubuntu comes with 2.7.6 and I need something in particular from 2.7.11.
Thanks!
First of all get setuptools
apt-get update
apt-get install python-setuptools
apt-get install python-pip
If you plan to use git and other tools install
apt-get install git
apt-get install python-dev
Once pip and setuptools are in place you can get any modules with either pip
or easy_install
Get setuptools from https://pypi.python.org/pypi/setuptools
run
wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
now you got setuptools and ez_setup.py - locate this file and run
python ez_setup.py
Now you have easy_install, so you can either use it or install pip:
easy_install pip
At that point you should be able to use pip.
I'm trying to install Pillow (Python module) using pip, but it throws this error:
ValueError: jpeg is required unless explicitly disabled using --disable-jpeg, aborting
So as the error says, I tried:
pip install pillow --global-option="--disable-jpeg"
But it fails with:
error: option --disable-jpeg not recognized
Any hints how to deal with it?
There is a bug reported for Pillow here, which indicates that libjpeg and zlib are now required as of Pillow 3.0.0.
The installation instructions for Pillow on Linux give advice of how to install these packages. Note that not all of the following packages may be missing on your machine (comments suggest that only libjpeg8-dev is actually missing).
pip / PyPi (Pillow>3.4.2)
The latest releases of Pillow are available on PyPi as wheels — the new standard packaging mechanism for Python. These prebuilt packages include all neccessary binary dependencies to allow Pillow to run and should be used if you want to install Pillow using PyPi
To use wheels, you need to have a version of pip>=1.4. If you are using an earlier version (pip --version) upgrade pip using the following:
pip install --upgrade pip
Once pip is upgraded, pip install will use platform-specific wheel files by default if they are available. Use the following command to upgrade Pillow to the latest version available on PyPi:
pip install --upgrade pillow
Ubuntu 12.04 LTS or Raspian Wheezy 7.0
sudo apt-get install libtiff4-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.5-dev tk8.5-dev python-tk
Ubuntu 14.04
sudo apt-get install libtiff5-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk
Ubuntu 18.04
sudo apt install libjpeg8-dev zlib1g-dev
Fedora 20
The Fedora 20 equivalent of libjpeg8-dev is libjpeg-devel.
sudo yum install libtiff-devel libjpeg-devel libzip-devel freetype-devel lcms2-devel libwebp-devel tcl-devel tk-devel
Mac OS X (via Homebrew)
On Mac OS X with Homebrew this can be fixed using:
brew install libjpeg zlib
You may also need to force-link zlib using the following:
brew link zlib --force
Update April 2019: In Mojave the above will not work and you need to run the following as taken from this bug report on Pillow
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
Update July 2016: There is no longer a formula for zlib available in the main repository (Homebrew will prompt you to install lzlib which is a different library and will not solve this problem).
There is a formula available in the dupes repository. You can either tap this repository, and install as normal:
brew tap homebrew/dupes
brew install zlib
Or you can install zlib via xcode instead, as follows:
xcode-select --install
Thanks to phoenix, Panos Angelopoulou, nelsonvarela, benjaminz and Kal in the comments
After these are installed the pip installation of Pillow should work normally.
On Raspberry pi II, I had the same problem. After trying the following, I solved the problem. The solution is:
sudo apt-get update
sudo apt-get install libjpeg-dev
Thank you #mfitzp. In my case (CentOS) these libs are not available in the yum repo, but actually the solution was even easier. What I did:
sudo yum install python-devel
sudo yum install zlib-devel
sudo yum install libjpeg-turbo-devel
And now pillow's installation finishes successfully.
The quickest fix is upgrate the pip. Did worked for me:
pip install --upgrade pip
This worked for me to solve jpeg and zlib error :
C:\Windows\system32>pip3 install pillow --global-option="build_e
xt" --global-option="--disable-zlib" --global-option="--disable-jpeg"
This worked for me.
`sudo apt-get install libjpeg-dev`
brew install zlib
on OS X doesn't work anymore and instead prompts to install lzlib. Installing that doesn't help.
Instead you install XCode Command line tools and that should install zlib
xcode-select --install
I had the ValueError: zlib is required unless explicitly disabled using --disable-zlib but upgrading pip from 7.x to 8.y resolved the problem.
So I would try to update tools before anything else.
That can be done using:
pip install --upgrade pip
The alternative, if you don't want to install libjpeg:
CFLAGS="--disable-jpeg" pip install pillow
From https://pillow.readthedocs.io/en/3.0.0/installation.html#external-libraries
Working successfuly :
sudo apt install libjpeg8-dev zlib1g-dev
Anyone with Python 3.9 you can only install Pillow 8.0, Any version lower than that wouldn't work. For more check here.
So you can run it like this:
pip install Pillow==8.0.0
BTW this is tested on pip 21.0.1 (python 3.9) on MacOS Big Sur 11.2
Try
pip install pillow
If it doesn't work, try clearing the
cache by pip install --upgrade pip
Then again run
pip install pillow
On debian / ubuntu you only need:
libjpeg62-turbo-dev
So a simple sudo apt install libjpeg62-turbo-dev
and a pip install pillow
This is on CentOs 6.6. I am trying to set up a scientific python environment. I want to avoid Anaconda. When trying to install matplotlib, I get "ImportError: No module named pkg_resources". Full install history:
sudo yum install gcc-c++.x86_64
sudo yum install gcc
sudo yum install atlas atlas-devel lapack-devel blas-devel
sudo yum install python-devel
sudo pip install numpy
sudo pip install scipy
sudo pip install pandas
sudo pip install matplotlib
At the last step, I get the message
Complete output from command python setup.py egg_info:
The required version of distribute (>=0.6.28) is not available,
and can't be installed while this script is running. Please
install a more recent version first, using
'easy_install -U distribute'.
Then I do
sudo pip install --upgrade distribute
which installs distribute-0.7.3, setuptools-18.0.1. Then:
sudo pip install matplotlib
which results in:
File "/usr/bin/pip", line 5, in <module>
from pkg_resources import load_entry_point
ImportError: No module named pkg_resources
Any ideas?
Update
After the above steps, setuptools and pip are broken in this installation. From a python shell, doing help() followed by modules does not list setuptools. A search in the filesystem for setuptools directories reveals:
/usr/lib/python2.6/site-packages/setuptools-18.0.1.dist-info/
while the setuptools.pth file in /usr/lib/python2.6/site-packages/ contains a pointer to the non-existent ./setuptools-0.6c11-py2.6.egg-info.
At the same time, there is a directory
/usr/share/doc/python-setuptools-0.6.10/
After all this, pip no longer works.
#pavan they said CentOS, so apt is unlikely to help them.
They could, though, do :
yum remove python-setuptools
yum install python-setuptools
(my also need to reinstall pip: yum install python-pip )
And that might fix the problem.
Try this for OS supporting apt-get (Ubuntu etc)
sudo apt-get install python-pkg-resources python-setuptools --reinstall
Try install python-pip (and dependencies):
yum install python-pip
This solved my problem (Centos release 6.8).
I have both python2.7 and python3.2 installed in Ubuntu 12.04.
The symbolic link python links to python2.7.
When I type:
sudo pip install package-name
It will default install python2 version of package-name.
Some package supports both python2 and python3.
How to install python3 version of package-name via pip?
Ubuntu 12.10+ and Fedora 13+ have a package called python3-pip which will install pip-3.2 (or pip-3.3, pip-3.4 or pip3 for newer versions) without needing this jumping through hoops.
I came across this and fixed this without needing the likes of wget or virtualenvs (assuming Ubuntu 12.04):
Install package python3-setuptools: run sudo aptitude install python3-setuptools, this will give you the command easy_install3.
Install pip using Python 3's setuptools: run sudo easy_install3 pip, this will give you the command pip-3.2 like kev's solution.
Install your PyPI packages: run sudo pip-3.2 install <package> (installing python packages into your base system requires root, of course).
…
Profit!
You may want to build a virtualenv of python3, then install packages of python3 after activating the virtualenv. So your system won't be messed up :)
This could be something like:
virtualenv -p /usr/bin/python3 py3env
source py3env/bin/activate
pip install package-name
Short Answer
sudo apt-get install python3-pip
sudo pip3 install MODULE_NAME
Source: Shashank Bharadwaj's comment
Long Answer
The short answer applies only on newer systems. On some versions of Ubuntu the command is pip-3.2:
sudo pip-3.2 install MODULE_NAME
If it doesn't work, this method should work for any Linux distro and supported version:
sudo apt-get install curl
curl https://bootstrap.pypa.io/get-pip.py | sudo python3
sudo pip3 install MODULE_NAME
If you don't have curl, use wget. If you don't have sudo, switch to root. If pip3 symlink does not exists, check for something like pip-3.X
Much python packages require also the dev package, so install it too:
sudo apt-get install python3-dev
Sources:
python installing packages with pip
Pip latest install
Check also Tobu's answer if you want an even more upgraded version of Python.
I want to add that using a virtual environment is usually the preferred way to develop a python application, so #felixyan answer is probably the best in an ideal world. But if you really want to install that package globally, or if need to test / use it frequently without activating a virtual environment, I suppose installing it as a global package is the way to go.
Well, on ubuntu 13.10/14.04, things are a little different.
Install
$ sudo apt-get install python3-pip
Install packages
$ sudo pip3 install packagename
NOT pip-3.3 install
The easiest way to install latest pip2/pip3 and corresponding packages:
curl https://bootstrap.pypa.io/get-pip.py | python2
pip2 install package-name
curl https://bootstrap.pypa.io/get-pip.py | python3
pip3 install package-name
Note: please run these commands as root
I had the same problem while trying to install pylab, and I have found this link
So what I have done to install pylab within Python 3 is:
python3 -m pip install SomePackage
It has worked properly, and as you can see in the link you can do this for every Python version you have, so I guess this solves your problem.
Old question, but none of the answers satisfies me. One of my systems is running Ubuntu 12.04 LTS and for some reason there's no package python3-pip or python-pip for Python 3. So here is what I've done (all commands were executed as root):
Install setuptools for Python3 in case you haven't.
apt-get install python3-setuptools
or
aptitude install python3-setuptools
With Python 2.4+ you can invoke easy_install with specific Python version by using python -m easy_install. So pip for Python 3 could be installed by:
python3 -m easy_install pip
That's it, you got pip for Python 3. Now just invoke pip with the specific version of Python to install package for Python 3. For example, with Python 3.2 installed on my system, I used:
pip-3.2 install [package]
If you have pip installed in both pythons, and both are in your path, just use:
$ pip-2.7 install PACKAGENAME
$ pip-3.2 install PACKAGENAME

This is a duplicate of question #2812520
If your system has python2 as default, use below command to install packages to python3
$ python3 -m pip install <package-name>
Easy enough:
sudo aptitude install python3-pip
pip-3.2 install --user pkg
If you want Python 3.3, which isn't the default as of Ubuntu 12.10:
sudo aptitude install python3-pip python3.3
python3.3 -m pip.runner install --user pkg
You can alternatively just run pip3 install packagename instead of pip,
Firstly, you need to install pip for the Python 3 installation that you want. Then you run that pip to install packages for that Python version.
Since you have both pip and python 3 in /usr/bin, I assume they are both installed with a package manager of some sort. That package manager should also have a Python 3 pip. That's the one you should install.
Felix' recommendation of virtualenv is a good one. If you are only testing, or you are doing development, then you shouldn't install the package in the system python. Using virtualenv, or even building your own Pythons for development, is better in those cases.
But if you actually do want to install this package in the system python, installing pip for Python 3 is the way to go.
Although the question relates to Ubuntu, let me contribute by saying that I'm on Mac and my python command defaults to Python 2.7.5. I have Python 3 as well, accessible via python3, so knowing the pip package origin, I just downloaded it and issued sudo python3 setup.py install against it and, surely enough, only Python 3 has now this module inside its site packages. Hope this helps a wandering Mac-stranger.
Execute the pip binary directly.
First locate the version of PIP you want.
jon-mint python3.3 # whereis ip
ip: /bin/ip /sbin/ip /usr/share/man/man8/ip.8.gz /usr/share/man/man7/ip.7.gz
Then execute.
jon-mint python3.3 # pip3.3 install pexpect

Cleaning up...
You should install ALL dependencies:
sudo apt-get install build-essential python3-dev python3-setuptools python3-numpy python3-scipy libatlas-dev libatlas3gf-base
Install pip3(if you have installed, please look step 3):
sudo apt-get install python3-pip
Iinstall scikit-learn by pip3
pip3 install -U scikit-learn
Open your terminal and entry python3 environment, type import sklearn to check it.
To install pip for python3 use should use pip3 instead of pip.
To install python in ubuntu 18.08 bionic
before installing a version of python, activate virtual environment so that it won't have any problem in a future versions of python.
virtualenv -p /usr/bin/python3 py3env
source py3env/bin/activate
then install the actual python version you want.
>> sudo apt-get install python3.7
To install the required pip package in ubuntu
>> sudo apt-get install python3-pip
You Can Simply type in terminal/console .
Commands
sudo apt update
sudo apt upgrade
sudo apt install python3-pip3
pip3 install package-name
Another way to install python3 is using wget. Below are the steps for installation.
wget http://www.python.org/ftp/python/3.3.5/Python-3.3.5.tar.xz
tar xJf ./Python-3.3.5.tar.xz
cd ./Python-3.3.5
./configure --prefix=/opt/python3.3
make && sudo make install
Also,one can create an alias for the same using
echo 'alias py="/opt/python3.3/bin/python3.3"' >> ~/.bashrc
Now open a new terminal and type py and press Enter.
