1. The R sessionInfo()
2. The command to install xgboost if you are not installing from source

Steps to reproduce

What have you tried?

1.rebuild the xgboost,doesnt work

[AbdealiLoKo]

How are you rebuilding xgboost ?
Did you do a make clean_all and followed by make -j ?

hello,thanks for your cares,the problem has been resolved.the key point is that i installed anaconda and the libgomp.so.1 and libstdc++.so.6 file in anaconda seems out of time,lacking GOMP_4.0 and some other files,but in Ubuntu 16.04 the corresponding files is new enough ,the solution is to make some link files to update the corresponding files in anaconda

[AbdealiLoKo]

Ah, awesome. Do close the issue so that it doesn't come up as unresolved

@yinshurman would you mind posting the solution steps!
thanx in advance

[yinshurman]

step 1 : use the following commands to check whether the libgomp.so.1 file in anconda contains the required version GOMP_4.0 (replace the path by your own in all the steps) :
strings /home/yin/anaconda3/bin/../lib/libgomp.so.1 |grep GOMP ( if there is not GOMP_4.0 version ,go to step 2, else leave a comment )
step 2: to check libgomp.so.1 in your OS:
sudo find / -name libgomp.so.1*
step3: check the link in anaconda ：
ls -al /home/yin/anaconda3/bin/../lib/libgomp.so.1 if the link not link to the newest verison in step 2 's list , then make a new link to update it by:
sudo rm -rf /home/yin/anaconda3/bin/../lib/libgomp.so.1
sudo ln -s <path of the newest version libgomp file in your OS > <path in anaconda>
(for example sudo ln -s /usr/.../libgomp.so.XXX /home/yin/anaconda3/bin/..libgomp.so.1 )
ps:without my computer at hands,I can't remember the concrete path ,but this method resolve my problems,in fact ,in my case, not only GOMP_4.0 but also some other files are not found(for example,this https://github.com/dmlc/xgboost/issues/1700 ), this solution works well too.

[BaljeetSinghCheema]

It worked. Thank you so much @yinshurman

[AkashDevgun]

@yinshurman ....can you please tell me step by step i am not find out the solution for the following error:

import xgboost
SError: /home/akash/anaconda2/bin/../lib/libgomp.so.1: version `GOMP_4.0' not found (required by /home/akash/anaconda2/lib/python2.7/site-packages/xgboost/./lib/libxgboost.so

[datorse]

Yes it works. These steps perfectly worked for libeemd and pyeemd package. Thanks

Is there any way to update the libgomp lib in anaconda
After I make a symbolic file to a system one, it instead report an error about libstdc++.so.6.

[yinshurman]

Maybe you can try conda install libgcc ,which can resolve the problems like this,too @jiqiujia

[jiqiujia]

@yinshurman Thanks a lot. It works!

[jxlijunhao]

@yinshurman Thanks a lot. It works

[gyang274]

I experienced a similar issue, fixed it by updating the anaconda gcc from 4.8.5 to 5.4.0:

conda install -c salford_systems gcc-5

[Grumby]

@yinshurman I had problems with libgomp.so.1 and libstdc++.so.6 and it worked for both. Thank you.

`GOMP_4.0' not found
This is an error due to mismatch of versions xgboost was built with and versions in the conda environment whcih xgboost uses to at runtime.
The easiest way to solve the problem and not break anything is to build xgboost explicitly with conda's libraries, for which the following needs to be done:

1. Start a fresh terminal
   export LD_LIBRARY_PATH=~/work/anaconda3/lib #or whatever your anaconda install path is
2. make sure your default python is from anaconda distro:
   which python
   If not, add anaconda distro to PATH:
   export PATH=~/work/anaconda3/bin:$PATH
3. Rebuild and reinstall xgboost
   cd ~/xgboost
make clean_all
make -j4
cd python-package
python setup.py install
4. verify

you can now close the terminal, and start a new one, LD_LIBRARY_PATdoes not need to persist, as conda's env. got required libraries.
