Discussion and troubleshooting on PyPI (pip) installation (the newest 0.6 version)

[phunterlau]

After some good tries (#1445), the PyPI xgboost installation is updated to the most recent code https://pypi.python.org/pypi/xgboost/ and Mac/Linux users can install it via pip install xgboost. I recommend using Anaconda or Miniconda python release for easier dependency resolution on numpy scipy and scikit-learn, and update pip (setuptools) to the most recent version.

Before typing pip install xgboost and happy waiting, please follow the instruction on the PyPI page as copied here:

• Since this package contains C++ source code, pip needs a C++ compiler from the system to compile the source code on-the-fly. Please follow the following instruction for each supported platform.
• Note for Mac OS X users: please install gcc from brew by brew tap homebrew/versions; brew install gcc --without-multilib firstly.
• Note for Linux users: please install gcc by sudo apt-get install build-essential firstly or using the corresponding package manager of the system.
• Note for windows users: this pip installation may not work on some windows environment, and it may cause unexpected errors. pip installation on windows is currently disabled for further investigation, please install from Github.

If everything is fine, after hearing CPU fan noise for couple of minutes (it is compiling on the fly), one should see something like this:

This package is tested with Mac OS X 10.10, ubuntu 14/16 and CentOS 7 with no problem. Please report any issues or installation difficulties here, with detailed information. For having the debug output, please use pip install -v xgboost. Thanks.

@hemoely can you provide the full log somewhere, e.g. dropbox? P.S. you have g++ too, right?
@byronliwei what is your system, Ubuntu, Mac or CentOS? also, can you provide the full log somewhere, e.g. dropbox?

@byronliwei seems like you don't have either gcc-5 or clang-omp, so the compiling fails. Please install either one from brew.

[garyci]

@byronliwei brew install clang-omp

[rashmibanthia]

I am hoping this is the right place for the following problem: (If not please let me know where to post this)
I have OSX El Capitan 10.11.5, Anaconda Python 3.5.
I have done install and uninstall multiple times with brew install gcc --without-multilib
brew installs gcc6 and xgboost needs gcc5. Here’s the exact error I am getting:

Any help really appreciated. Thank you!

Makefile in Mac now requires gcc-5, maybe we should just ask gcc-6?

[GradientBoostingGPA]

Hi,

I got the following error when I tried to install xgboost.
Do you know why I got the following eroor?
I am using Mac and I have run "brew tap homebrew/versions; brew install gcc --without-multilib"
Thanks in advance!

[phunterlau]

@liuxu1104 please install either gcc-5 or clang-omp from brew. the error log shows you have neither of these compilers.

[phunterlau]

@liuxu1104 seems like you have gcc-6 instead of gcc-5. maybe we should just require gcc-6 or clang-omp for Mac in PyPI, and discard gcc-5? Meanwhile, you can always install from github, and edit make/config.mk by changing the CC and CXX to your compilers.

@phunterlau Thank you ! I build it on OS X (El Capitan 10.11.5, Anaconda Python 3.5) and it worked. Also installed gcc5 brew install gcc5 --without-multilib (There were few notes and warning, but I can import xgboost from python)

[GradientBoostingGPA]

@phunterlau Solved!
Thank you!

[davechallis]

It's worth noting that clang-omp was removed from brew (Homebrew/homebrew-core@c57e307), so anyone on updated OS X + homebrew will get a 'not found' error.

[phunterlau]

@davechallis so, should we just remove clang-omp support for future?

[davechallis]

@phunterlau it looks like the opemmp functionality is available in current versions of LLVM, so using that instead should work (but I can't test it on older versions of Mac OS X easily, so not sure if homebrew has the same channels/software available for them).

I.e. brew install llvm provides /usr/local/opt/llvm/bin/clang and /usr/local/opt/llvm/bin/clang++, both of which support the -fopenmp flag.

Changing xgboost to then use these compilers (or gcc-6) on mac os x worked for me.

[rayquazasnow]

I've already installed gcc-6, but still cannot install xgboost with the error below,
so I follow your advice to install clang-omp from brew but it still failed.

[phunterlau]

@rayquazasnow seems like you have gcc-6 while the current pip install xgboost requires either gcc-5 or clang-omp++ since brew provided gcc-5 at that time. Meanwhile, you can install from github, or brew install --with-clang llvm for having clang++ . I will find a stable version and update PyPI to gcc-6 along with other fixes.

[rayquazasnow]

@phunterlau thanks for your advice. I successfully installed llvm by brew install --with-clang llvm. However, pip install xgboost still can not work(the same error code shown above). Should I uninstall gcc-6 and install gcc-5 instead?

brew install gcc --without-multilib
Error: gcc-6.1.0_1 already installed
To install this version, first 'brew unlink gcc'

[phunterlau]

@rayquazasnow please post the new error message from pip before downgrade gcc. Or, install from github.

[rayquazasnow]

@phunterlau Here is the new error after I install llvm. Still with the message "/bin/sh: clang-omp++: command not found"

[phunterlau]

@rayquazasnow can you try which clang-omp++ and see the result? It should be something like this or the installation didn't work:

$ which clang-omp++
/usr/local/bin/clang-omp++

[rayquazasnow]

@phunterlau there is no response with which clang-omp++. It seems like the installation didn't work.
$ brew install --with-clang llvm
/usr/local/bin/brew: line 28: /usr/local/Library/Homebrew/brew.sh: No such file or directory
$ brew install clang++
/usr/local/bin/brew: line 28: /usr/local/Library/Homebrew/brew.sh: No such file or directory

$ which clang
/usr/bin/clang
$ which llvm
$ which clang++
/usr/bin/clang++

[phunterlau]

@rayquazasnow you might want to install or re-install brew firstly, seems like your brew installation was broken.

[benman1]

I did brew install gcc6 --without-multilib. That got it rolling.

[AbdealiLoKo]

I didn't quite get why clang-omp or gcc is needed in Mac.
The log says that the single threaded version has been built, but it still can't find the library.

It says:

Successfully build single-thread xgboost
If you want multi-threaded version
See additional instructions in doc/build.md

but finally gives:

__builtin__.XGBoostLibraryNotFound: Cannot find XGBoost Libarary in the candicate path, did you install compilers and run build.sh in root path?
List of candidates:
/private/var/folders/m3/yqpf5xhs1rxbzyh_hz4lhx040000gn/T/pip-build-cEIF0a/xgboost/xgboost/libxgboost.so

So, as I see it the issue is something else. It should be installing xgboost with the single threaded version.

I can install xgboost from git without gcc nor clang-omp++ ... using just the bash build.sh

[phunterlau]

@AbdealiJK if there is no gcc or clang-omp, the script would call the default clang from Xcode which only supports single thread and loses the advantage of XGBoost parallelization.

[AbdealiLoKo]

@phunterlau while I completely agree with that, I don't see why the installation failure happens. I don't understand why the error would be:

builtin.XGBoostLibraryNotFound: Cannot find XGBoost Libarary in the candicate path, did you install compilers and run build.sh in root path?

[AbdealiLoKo]

@phunterlau I was checking the pypi package to understand the problem and found that the way of calling make without openmp was invalid (and it always used -fopenmp). And that the default gcc/g++ was never an option.

Modifying it with these diffs worked for me:

@AbdealiJK Thanks. PyPI 's makefile was quick-n-dirty way and it didn't consider all scenarios . Would you like to send a PR for updating this?

[AbdealiLoKo]

Would love to, but I'm not sure what to modify - because the github build.sh and Makefile uses the correct versions.

The pypi package seems to have a different structure and different files than github (maybe they just need to be updated?)

[phunterlau]

@AbdealiJK oh, now I remember it: PyPI version was a little bit outdated, it was created before the Makefile fix. Let me update it. Thanks.

[xgdgsc]

Would you consider uploading official prebuild wheel packages to pypi? It would make windows and mac users installation easier. Now windows users can get unofficial builds at http://www.lfd.uci.edu/~gohlke/pythonlibs/#xgboost

[phunterlau]

@xgdgsc precompiled package is good. Is the Windows precompiled package made by you or someone that you know? can you add the recipe to the official guideline so other people can start using it? I have seen much pain on this issue list when installing windows version. As to precompiled PyPI build for Mac/Linux, we have to separate them since PyPI doesn't tell difference between platforms. Definitely a good idea, in short.

[xgdgsc]

That package is not made by me or anyone I know, but that page is famous among windows python users. I would suggest uploading precompiled packages to pypi just like what I do here. Pip would automatically select the right wheel package when user install. This way we just add the warning of installing the VC redistribution packages if loading the prebuilt binary failed. Another option is to use conda-forge to build the packages for anaconda users.

Do we need to upgrade gcc, can we any older version which can run with gcc 4. Isn't gcc OS related compiler.

Thanks
Krishna

[phunterlau]

@kishore432 you can try github install and manually edit the compiler requirement in Makefile

I was pip-installing xgboost 0.6a2 in a CentOS container where make was missing. The installation claimed to be successful, but of course the lib couldn't be loaded. I think it would help if installation problems caused an error at installation time, rather than at runtime.

Excerpts from the verbose pip output:

These error messages when pip-installing in a Python 3 environment are caused by print statements using Python 2 syntax. They don't seem to cause any harm though. In this case, I'm happy that the installation problem doesn't trigger an error at installation time.

brew install gcc-5 solved all problems in MacOS Sierra 10.12.6.

I have MacOS El Captain, and I have installed gcc 49 and gcc 5, and yet I can not install xgboost using pip install xgboost. I receive bunch of messages with the following red error message at the bottom:

Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/9x/9vqgp6tn69d5mxkspzw840qr0000gn/T/pip-build-GuPlss/xgboost/

I have seen many complained over the same issue, but I did not find any satisfying response. Maybe I have missed it.

Thanks

I could not get pip install xgboost working, but I followed this instruction here: https://www.ibm.com/developerworks/community/blogs/jfp/entry/Installing_XGBoost_on_Mac_OSX?lang=en

where I used git-clone and now I have xgboost.
