I have run
python setup.py sdist --formats=gztar,zip bdist_wheel
and then
python setup.py install
The result is that the egg files are created in the site-packages directory but not the <package-name>/<package-source files>:
$ls /usr/local/lib/python3.7/site-packages/infix*
/usr/local/lib/python3.7/site-packages/infixpy-0.0.3-py3.7.egg
/usr/local/lib/python3.7/site-packages/infixpy.egg-link
/usr/local/lib/python3.7/site-packages/infixpy-0.0.4-py3.7.egg
Notice that the directory infix was not created - and thus none of the source code was copied. What am I missing / not understanding in this local installation process?
Update When I had run
pip3 install infixpy
there was an additional directory infix and the source code was included in that directory. Running the local or devel modes of setup.py install was not causing that code to be updated and - crucially - the stacktraces from running any python code (even in a completely new ipython repl) was showing only the older / pip3 installed code. In particular the file __init__.py So my observation has been that the source file :
/usr/local/lib/python3.7/site-packages/infixpy/__init__.py
is an accurate reflection of what the python executable were using. #phd is mentioning that the source code is already included in the egg. So then I do not understand the relationship between the source code in the egg and the source code in that subdirectory - which in the lastest run of mine is completely missing.
The following commands all yield slightly different results:
pip install .: installed as uncompressed package directories and a XXX.dist-info directory
pip install infixpy: same as previous, but installed from an (remote) index (per default PyPI), not from the local directory
python setup.py install: installed as a zipped file XXX.egg
pip install --editable . or python setup.py develop: not installed, but linked as a XXX.egg-link file
So depending on the commands entered, the content of site-packages is different.
Now this is what you say you have:
$ls /usr/local/lib/python3.7/site-packages/infix*
/usr/local/lib/python3.7/site-packages/infixpy-0.0.3-py3.7.egg
/usr/local/lib/python3.7/site-packages/infixpy.egg-link
/usr/local/lib/python3.7/site-packages/infixpy-0.0.4-py3.7.egg```
This is a bit surprising, since theoretically there are 3 versions of your project that are importable (0.0.3, 0.0.4, and develop/editable). I am not sure which one is used by the Python interpreter in this case. You might want to run pip uninstall infixpy a couple of times to start fresh and alleviate these uncertainties. You can then experiment with the commands mentioned above and see how they impact the content of site-packages along with inspecting the result of pip show infixpy.
http://xgboost.readthedocs.org/en/latest/python/python_intro.html
On the homepage of xgboost(above link), it says:
To install XGBoost, do the following steps:
You need to run make in the root directory of the project
In the python-package directory run
python setup.py install
However, when I did it, for step 1 the following error appear:
make : The term 'make' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the
spelling of the name, or if a path was included, verify that the path is correct and try again.
then I skip step1 and did step 2 directly, another error appear:
Traceback (most recent call last):
File "setup.py", line 19, in <module>
LIB_PATH = libpath['find_lib_path']()
File "xgboost/libpath.py", line 44, in find_lib_path
'List of candidates:\n' + ('\n'.join(dll_path)))
__builtin__.XGBoostLibraryNotFound: Cannot find XGBoost Libarary in the candicate path, did you install compilers and run build.sh in root path?
Does anyone know how to install xgboost for python on Windows10 platform? Thanks for your help!
In case anyone's looking for a simpler solution that doesn't require compiling it yourself:
download xgboost whl file from here (make sure to match your python version and system architecture, e.g. "xgboost-0.6-cp35-cp35m-win_amd64.whl" for python 3.5 on 64-bit machine)
open command prompt
cd to your Downloads folder (or wherever you saved the whl file)
pip install xgboost-0.6-cp35-cp35m-win_amd64.whl (or whatever your whl file is named)
If you find it won't install because of a missing dependency, download and install the dependency first and retry.
If it complains about access permissions, try opening your command prompt as Administrator and retry.
This gives you xgboost and the scikit-learn wrapper, and saves you from having to go through the pain of compiling it yourself. :)
Note that as of the most recent release the Microsoft Visual Studio instructions no longer seem to apply as this link returns a 404 error:
https://github.com/dmlc/xgboost/tree/master/windows
You can read more about the removal of the MSVC build from Tianqi Chen's comment here.
So here's what I did to finish a 64-bit build on Windows:
Download and install MinGW-64: http://sourceforge.net/projects/mingw-w64/
On the first screen of the install prompt make sure you set the Architecture to x86_64 and the Threads to win32
I installed to C:\mingw64 (to avoid spaces in the file path) so I added this to my PATH environment variable: C:\mingw64\mingw64\bin
I also noticed that the make utility that is included in bin\mingw64 is called mingw32-make so to simplify things I just renamed this to make
Open a Windows command prompt and type gcc. You should see something like "fatal error: no input file"
Next type make. You should see something like "No targets specified and no makefile found"
Type git. If you don't have git, install it and add it to your
PATH.
These should be all the tools you need to build the xgboost project. To get the source code run these lines:
cd c:\
git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
git submodule init
git submodule update
cp make/mingw64.mk config.mk
make -j4
Note that I ran this part from a Cygwin shell. If you are using the Windows command prompt you should be able to change cp to copy and arrive at the same result. However, if the build fails on you for any reason I would recommend trying again using cygwin.
If the build finishes successfully, you should have a file called xgboost.exe located in the project root. To install the Python package, do the following:
cd python-package
python setup.py install
Now you should be good to go. Open up Python, and you can import the package with:
import xgboost as xgb
To test the installation, I went ahead and ran the basic_walkthrough.py file that was included in the demo/guide-python folder of the project and didn't get any errors.
I installed XGBoost successfully in Windows 8 64bit, Python 2.7 with Visual Studio 2013 (don't need mingw64)
Updated 15/02/2017
With newer version of XGBoost, here are my steps
Step 1. Install cmake https://cmake.org/download/
Verify cmake have been installed successfully
$ cmake
Usage
cmake [options] <path-to-source>
cmake [options] <path-to-existing-build>
...
Step 2. Clone xgboost source
$ git clone https://github.com/dmlc/xgboost xgboost_dir
Step 3. Create Visual Studio Project
$ cd xgboost_dir
$ mkdir build
$ cd build
$ cmake .. -G"Visual Studio 12 2013 Win64"
Step 4. Build Visual Studio 2013 project
Open file xgboost_dir/build/ALL_BUILD.vcxproj with Visual Studio 2013
In Visual Studio 2013, open BUILD > Configuration Manager...
choose Release in Active solution configuration
choose x64 in Active solution platform
Click BUILD > Build Solution (Ctrl + Shift +B)
After build solution, two new files libxgboost.dll and xgboost.exe are created in folder xgboost_dir/lib
Step 5. Build python package
Copy file libxgboost.dll to xgboost_dir/python-package
Change directory to xgboost_dir/python-package folder
Run command python setup.py install
Verify xgboost have been installed successfully
$ python -c "import xgboost"
Old Answer
Here are my steps:
git clone https://github.com/dmlc/xgboost
git checkout 9bc3d16
Open project in xgboost/windows with Visual Studio 2013
In Visual Studio 2013, open BUILD > Configuration Manager...,
choose Release in Active solution configuration
choose x64 in Active solution platform
Rebuild xgboost, xgboost_wrapper
Copy all file in xgboost/windows/x64/Release folder to xgboost/wrapper
Go to xgboost/python-package, run command python setup.py install
Check xgboost by running command python -c "import xgboost"
I just installed xgboost both for my python 2.7 and python 3.5, anaconda, 64bit machine and 64 bit python.
both VERY simple, NO VS2013 or git required.
I think it works for normal python, too.
If you use python 3.5:
1: download the package here, the version depends on your python version, python3.5 or python 3.6, 32bit or 64bit.
2: use the command window, use cd to make the download folder as your pwd, then use
pip install filename.whl
OK, finished.
For more detailed steps, see this answer
if you use python 2.7, you do NOT need to download the VS2013 to build it yourself, because I have built it, you can download the file I built and install it directly
1: Download it here by google drive
2: Download it, decompress it, paste it here:
"your python path\Lib\site-packages"
Then you should have something look like this:
3: In python-package folder showed above, use cmd window, cd there and run
python setup.py install
use this code
import xgboost
in your python to check whether you have installed mingw-64 or not, No error information means you have installed the mingw-64 and you are finished.
If there are error information
"WindowsError: [Error 126] "
That means you have not installed mingw-64, and you have one more step to go.
Download the mingw-64 here: http://sourceforge.net/projects/mingw-w64/
Choose x86_64 instead of the default "i686" when you installed the mingw-64,
then add "your install path\x86_64-6.2.0-posix-seh-rt_v5-rev1\mingw64\bin;" to your PATH, it should be something like this:
"C:\Program Files\mingw-w64\x86_64-6.2.0-posix-seh-rt_v5-rev1\mingw64\bin;"
(this is mine).
Don't forget the ";" in the PATH.
Then you are finished,you can use
import xgboost
in your python to check that, Yeah!
PS: if you don't know how to add path, just google it to get solutions. Don't worry, it's very simple.
If You are installing XGBoost for a particular Project and You are using Pycahrm then you need to follow the procedures given below:
Download xgboost‑0.72‑cp36‑cp36m‑win_amd64.whl from Here (as I am using Python 3.6 if you use different version of Python like 2.7 then you need to install xgboost‑0.72‑cp27‑cp27m‑win_amd64.whl).
Copy the to your Project Interpreter directory. You can find the directory of Project Interpreter by clicking File -> Settings -> Project Interpreter from Pycharm.
Open Command Prompt. Go to directory to you Project Interpreter from cmd. Write the following command: pip install xgboost-0.72-cp36-cp36m-win_amd64.whl
On windows 10 , with python 3.6, below command worked.
From Anaconda Prompt, below command can be used directly. The screenshot is attached as proof.
pip install xgboost
After build the c++ version, copy the release dll and lib files in ../windows/x64/Release/..(if you build x64 version) to ../wrapper/ then run python setup.py install
I followed the steps listed in https://www.kaggle.com/c/otto-group-product-classification-challenge/forums/t/13043/run-xgboost-from-windows-and-python. I will summarize what I did below.
1) Download Visual Basic Studio. You can download the community edition at visual studio website. There is a "free visual studio button on the upper right corner"
2) Copy all content from the git hub repository of xgboost/tree/master/windows and Open Visual studio existing project on Visual studio
3) There are a couple of drop down menus you need to select ( "Release" and "X64" and then select build --> build all from the upper menu. It should look something like the attached screenshot.
4) if you see the message ========== Build: 3 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========, it is all good
5) Browse to python-packages folder where the setup file for XGB resides and run the install command 'python setup.py install'.
You can find a similar thread at Install xgboost under python with 32-bit msys failing
Hope this helps.
To add to the solution by Disco4ever for those attempting to build on 32bit Windows machines.
After doing step 6 and creating a config.mk file you need to go into this file and edit the following lines to remove the -m64 flag
export CXX=g++ -m64
export CC=gcc -m64
Adding "git checkout 9a48a40" to Disco4Ever's solution above worked for me:
git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
git checkout 9a48a40
git submodule init
git submodule update
This was originally posted by Cortajarena here:
https://github.com/dmlc/xgboost/issues/1267
Also, for what it's worth, I originally had 32 bit Python running on my 64 bit machine and I had to upload 64 bit Python for XGBoost to work.
Thanks to disco4ever answer. I was trying to build xgboost for Python Anaconda environment in my windows 10 64 bit machine. Used Git, mingw64 and basic windows cmd.
Everthing worked for me till the copy step: cp make/mingw64.mk config.mk, as I was using windows cmd I modified it to copy c:\xgboost\make\mingw64.mk c:\xgboost\config.mk
when I proceeded to the next step : make -j4, I got error that build failed. At this stage after so much frustration just tired something different by clicking on build.sh (shell script). It started executing and auto finished.
Then I executed the same step make -j4, to my awe build was successful. I have seen the most awaited xgboost.exe file in my xgboost folder.
I then proceeded with further steps and executed python setup.py install. finally everything installed perfectly. Then I went to my spyder and checked whether it is working or not. But I was one step away to my happiness because I was still seeing the import error.
Closed all command prompts (Anaconda, Git bash, Windows CMD, cygwin terminal) then again opened spyder and typed 'import xgboost'. SUCCESS, No ERROR.
Once again thank you for everyone.
You can install xGBoost using either Visual Studio or minGW. Since, the official xgboost website says that MSVC build is not yet updated, I tried using mingw64.
I am running xgboost (python package) on my win7 x64. Steps I followed were:
1) Follow Disco4Ever's steps for ming64 installation (mentioned above in the answers).
2) Install Git for windows. windows download link. This will also install Git Bash. Add git-installation-directory\cmd to your system environment variable PATH list.
3) Now clone xGBoost in desired location. Type the following in cmd:
git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
git submodule init
git submodule update
cp make/mingw64.mk config.mk
make -j4
4) In xgboost's root directory there should be a shell script named "build". Open it. It'll open up a Git Bash and start building. After building, xgboost.exe file will be created.
5) Now install python package :
cd python-package
python setup.py install
You can test by importing xgboost in python.
It took a whole day, but I successfully installed xgboost on windows 7 64-bit box using TDM-GCC with OpenMP enabled, instead of MingW following this link - http://dnc1994.com/2016/03/installing-xgboost-on-windows/
Here's a very helpful link with important points to pay attention to during installation. It's very important to install "openmp". Otherwise you'll get error message.
The link provides a step by step instruction for installing. Here's some quote:
Building Xgboost
To be fair, there is nothing wrong about the official guide for
installing xgboost on Windows. But still, I’d love to stress several
points here to save your time.
git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
wget https://www.dropbox.com/s/y8myex4bnuzcp03/Makefile_win?dl=1
cp Makefile_win Makefile
cp make/mingw64.mk config.mk
mingw32-make
Makefile_win is a modified version (thanks to Zhou Xiyou) of the
original Makefile to suit the building process on Windows. You can
wget it or download it here. Be sure to use a UNIX shell for thi
because Windows CMD has issue with mkdir -p command. Git Bash is
recommended. Be sure to use --recursive option with git clone. Be sure
to use a proper MinGW. TDM-GCC is recommended. Note that by default it
wouldn’t install OpenMP for you. You need to specifiy it otherwise the
building would fail.
Another helpful link is the official procedure: official guide
Good luck!
I would like to add a small workaround to Disco4ever 's solution.
For me I was unable to perform cloning in cygwin. So the workaround is perform it in command prompt in windows and do the rest of the task in cygwin.
Use cd c:\xgboost in the 3rd line to make it work in cygwin. So the updated last part is like this.
cd c:\
git clone --recursive https://github.com/dmlc/xgboost
cd c:\xgboost
git submodule init
git submodule update
cp make/mingw64.mk config.mk
make -j4
And after installation is complete you can uninstall git and cygwin but xgboost and mingw64 must be kept as it is.
Note that: before "make -j4" use gcc -v to check your gcc version.
As to me, My environment is win10 + anaconda(python 2.7), when I run make -j4. It shows std::mutex error. After I use gcc- v It echo gcc4.7(anaconda's default gcc).After I choose my gcc to mingw64's 6.2 gcc ,then it works.
Finally, I use "/d/Anaconda2/python.exe setup.py install" install xgboost python packet.
You can install XGBoost using following 3 steps:
Gather information of your system (python version and system architecture - 32 bit or 64 bit)
download related .whl from https://www.lfd.uci.edu/~gohlke/pythonlibs/
e.g. if your python version is 3.7 and windows is 32 bit, then suitable file is:
xgboost‑0.72‑cp37‑cp37m‑win32.whl
run pip install yourdownloadedfile.whl
You can also find detailed steps here.
I use Jupyter notebook and I found a really simple way to install XGBoost within Anaconda:
Install Anaconda
Open Anaconda Navigator
In Environments, update the index and search for xgboost (in not-installed)
Pick libxgboost and py-xgboost and click 'Apply'
Done
It looks like I have multiple python installations, which are making things difficult -- e.g. pip will tell me that a package has been installed through pip freeze, but when attempting to use it within a program, I get an error that it does not exist. Here are a few diagnostic tests I've run:
>>> import sys
>>> sys.executable
'/usr/local/opt/python/bin/python2.7'
>>> sys.exec_prefix

As well as checking the path for python and some common tools:
which easy_install
/usr/local/bin/easy_install
which python
/usr/local/bin/python
which pip
/usr/local/bin/pip
How can I fix it, short of doing a clean re-install of OS X?
Edited to add $PATH and .bashrc info:
My $PATH is as follows:
Users/me/workspace/google-cloud-sdk/bin:/usr/local/bin:/Users/me/workspace/google-cloud-sdk/bin:/urs/local/bin:/Users/me/workspace/google-cloud-sdk/bin:/urs/local/bin:/Users/me/workspace/google-cloud-sdk/bin:usr/local/python:usr/bin/python:/Library/Frameworks/Python.framework/Versions/2.7/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/usr/texbin: No such file or directory
-- the fact that it is returning an error makes me suspect that I've set up my .bash_profile wrong somehow. These are the only modifications I have made:
#Set architecture flags
export ARCHFLAGS="-arch x86_64"
#Ensure user-installed binaries take precedence
export PATH=/usr/local/bin:$PATH
#Load .bashrc if it exists
test -f ~/.bashrc && source ~/.bashrc
# The next line updates PATH for the Google Cloud SDK.
source '/Users/me/workspace/google-cloud-sdk/path.bash.inc'
# The next line enables bash completion for gcloud.
source '/Users/me/workspace/google-cloud-sdk/completion.bash.inc'
And this is my .bashrc:
# pip should only run if there is a virtualenv currently activated
export PIP_REQUIRE_VIRTUALENV=true
# cache pip-installed packages to avoid re-downloading
export PIP_DOWNLOAD_CACHE=$HOME/.pip/cache
Couldn't find a way to fix it, so ended up doing a clean OS install and setting up a new python dev environment.
I'm trying to install Pandas using pip, but I'm having a bit of trouble. I just ran sudo pip install pandas which successfully downloaded pandas. However, it did not get downloaded to the location that I wanted. Here's what I see when I use pip show pandas:
---
Name: pandas
Version: 0.14.0
Location: /Library/Python/2.7/site-packages/pandas-0.14.0-py2.7-macosx-10.9-intel.egg
Requires: python-dateutil, pytz, numpy
So it is installed. But I was confused when I created a new Python Project and searched under System Libs/lib/python for pandas, because it didn't show up. Some of the other packages that I've downloaded in the past did show up, however, so I tried to take a look at where those were. Running pip show numpy (which I can import with no problem) yielded:
---
Name: numpy
Version: 1.6.2
Location: /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python
Requires:
Which is in a completely different directory. For the sake of confirming my error, I ran pip install pyquery to see where it would be downloaded to, and got:
Name: pyquery
Version: 1.2.8
Location: /Library/Python/2.7/site-packages
Requires: lxml, cssselect
So the same place as pandas...
How do I change the default download location for pip so that these packages are downloaded to the same location that numpy is in?
Note: There were a few similar questions that I saw when searching for a solution, but I didn't see anything that mentioned permanently changing the default location.
According to pip documentation at
http://pip.readthedocs.org/en/stable/user_guide/#configuration
You will need to specify the default install location within a pip.ini file, which, also according to the website above is usually located as follows
On Unix and Mac OS X the configuration file is: $HOME/.pip/pip.conf
On Windows, the configuration file is: %HOME%\pip\pip.ini
The %HOME% is located in C:\Users\Bob on windows assuming your name is Bob
On linux the $HOME directory can be located by using cd ~
You may have to create the pip.ini file when you find your pip directory. Within your pip.ini or pip.config you will then need to put (assuming your on windows) something like
[global]
target=C:\Users\Bob\Desktop
Except that you would replace C:\Users\Bob\Desktop with whatever path you desire. If you are on Linux you would replace it with something like /usr/local/your/path
After saving the command would then be
pip install pandas
However, the program you install might assume it will be installed in a certain directory and might not work as a result of being installed elsewhere.
You can set the following environment variable:
PIP_TARGET=/path/to/pip/dir
https://pip.pypa.io/en/stable/user_guide/#environment-variables
Open Terminal and type:
pip config set global.target /Users/Bob/Library/Python/3.8/lib/python/site-packages
except instead of
/Users/Bob/Library/Python/3.8/lib/python/site-packages
you would use whatever directory you want.
Follow these steps
pip config set global.target D:\site-packages to change install path
or py -m pip config --user --editor notepad edit
[global]
target = D:\site-packages
set environment variable to use download import xxx
PIP_TARGET=site-packages
PYTHONPATH=site-packages
3.pip config unset global.target, to upgrade pip py -m pip install --upgrade pip
#Austin's answer is outdated, here for more up-to-date solution:
According to pip documentation at
https://pip.pypa.io/en/stable/topics/configuration/
You will need to specify the default install location within a configuration file, which, also according to the website above is usually located as follows
Mac OS
$HOME/Library/Application Support/pip/pip.conf if directory $HOME/Library/Application Support/pip exists else $HOME/.config/pip/pip.conf.
The legacy “per-user” configuration file is also loaded, if it exists: $HOME/.pip/pip.conf.
The $HOME folder can be located by navigating to ~/ (cmd+shift+G in Finder; cmd+shift+. to show hidden files).
Windows
%APPDATA%\pip\pip.ini
The legacy “per-user” configuration file is also loaded, if it exists: %HOME%\pip\pip.ini
The %HOME% is located in C:\Users\Bob on windows assuming your username is Bob
Unix
$HOME/.config/pip/pip.conf, which respects the XDG_CONFIG_HOME environment variable.
The legacy “per-user” configuration file is also loaded, if it exists: $HOME/.pip/pip.conf.
On linux the $HOME directory can be located by using cd ~
You may have to create the configuration file when you find your pip directory. Put something like
[global]
target = /Library/Frameworks/Python.framework/Versions/Current/lib/python3.10/site-packages/
if you are on a Mac. Except that you would replace /Library/Frameworks/Python.framework/Versions/Current/lib/python3.10/site-packages/ with whatever path you desire. If you are on Linux you would replace it with something like /usr/local/your/path
After saving the command would then be
pip install pandas
However, the program you install might assume it will be installed in a certain directory and might not work as a result of being installed elsewhere.
Please note that
pip3 install pandas
might be the solution if your packages gets installed in the Python2 folder vs Python3.

e "MacPython" version, and not the system-provided version which is in:
/System/Library/Frameworks/Python.framework
==> ./configure --disable-debug --prefix=/usr/local/Cellar/postgresql/9.1.2 --datadir=/usr/local/Cellar/postgresql/9.1.2/shar
^C
Here's where python is located.
$ which python
/usr/local/bin/python
I modified my ~/.zshrc PATH from
export PATH=/Library/Frameworks/Python.framework/Versions/2.7/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11/bin
to
export PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11/bin
And although I'm getting python 64-bit errors, my version of python is 64-bit according to this SO post:
$ python -c 'import struct;print( 8 * struct.calcsize("P"))'
64
The problem pointed out in the referenced mailing list post is that the configure step isn't impacted by the PATH here. There's a whole other mechanism used to find things to link against; see Where do I set DYLD_LIBRARY_PATH on Mac OS X for a quick intro. You could try the suggested workaround given by the brew script--rename /Library/Frameworks/Python.framework/Versions/Current/Python to something else to get it out of the linker's search path, repeat the brew install, then put it back.
If you don't need Python bindings in your PostgreSQL, you can also just install it without Python bindings using brew install postgresql --no-python.
This command is installing the server, not the python bindings. Is that what you want? There is a installer for osx that will install the server for you.
Once you have done that, you can install the psycopg2 bindings directly from source.
