Improve this answer. You may need to create or edit user-config. Build how to invoke Python, include its headers, and link with its libraries. If you are using a unix-variant OS and you ran Boost's configure script, it may have generated a user-config. Python binaries were built, your user-config. If you haven't configured python in user-config. Build command line , Boost.
Build will automatically execute the equivalent of. However, that only happens when using the Boost. Python project file e. If instead you are linking against separately-compiled Boost. Python binaries, you should set up a user-config. If you have several versions of Python installed, or Python is installed in an unusual way, you may want to supply any or all of the following optional parameters to using python.
If you have both python 2. The first version configured 2. To build against python 2. If you have python installed in an unusual location, you might supply the path to the interpreter in the cmd-or-prefix parameter:. If you have a separate build of Python for use with a particular toolset, you might supply that toolset in the condition parameter:.
You can set up your user-config. This is supposed to work the other way, too targeting windows python with a Cygwin bjam but it seems as though the support in Boost. Build's toolsets for building that way is broken at the time of this writing.
Note that because of the way Boost. Build currently selects target alternatives , you might have be very explicit in your build requests. For example, given:. If—instead of letting Boost. Build construct and link with the right libraries automatically—you choose to use a pre-built Boost.
Python library, you'll need to think about which one to link with. The Boost. Python binary comes in both static and dynamic flavors. Take care to choose the right flavor for your application. The data structures used by the debugging configuration contain additional members, so a Python executable built with python debugging enabled cannot be used with an extension module or library compiled without it, and vice-versa.
Build does not automatically enable python debugging in its debug build variant which is the default. Instead there is a special build property called python-debugging that, when used as a build property, will define the right preprocessor symbols and select the right libraries to link with. Since that symbol is very commonly used even when Python is not present, Boost. To run the full test suite for Boost. However, when I drilled down in the directory, I saw only a Python lib file, but no Numpy lib file.
I knew there should be both Python and Numpy files, so something was clearly not right. After tearing my hair out for quite a while, I came across the B2 User Manual , and invocation options. In there, I found two option flags:. It is fixed from build and upwards. However, that build is still not generally available, you can get it from Windows Insiders Dev channel. Microsoft estimates a fix will be rolled out sometimes in January If you are affected by this and you can not get a Windows 10 Dev build you can solve it by downgrading numpy to version 1.
NOTE: The link here has more information about the bug. I have since then upgraded to the latest Windows Dev build and when I run the code, everything works fine:. Hmm, that does not look right. It turns out this is a bug in the build output, so nothing to worry about. We have in this post looked at how to build Boost. Python , and Numpy on a Windows 10 box:.
You can now start to use the libs created. If you have comments, questions etc. Niels Berglund Technology musings about coding and data. Pre-reqs What do we need to do this: Python: I have Python 3. I downloaded Boost 1. 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 error:. These should be all the tools you need to build the xgboost project. To get the source code run these lines:.
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. To install the Python package, do the following:. I just installed xgboost both for my python 2. PS: if you don't know how to add path, just google it to get solutions. Don't worry, it's very simple. Copy the to your Project Interpreter directory. Open Command Prompt. Go to directory to you Project Interpreter from cmd.
Write the following command: pip install xgboost
