error Library _loter_wrap.so not found

[ronaldrobles]

After installing
conda install numpy
conda install scipy
conda install pandas
conda install scikit-learn

And following the tutorial I have the error in:

Hi, thanks for the bug report. So if I'm correct, you have a Conda environment Meddly, and you have done something like that ?

source activate Meddly
conda install numpy
conda install scipy
conda install pandas
conda install scikit-learn
cd Loter/python-package
python setup.py install

Did you do recently clone the repository or do a git pull origin master ? because we introduced some modifications about compilation a few days ago.

Could you activate your Conda environment, and run import sys; print(sys.path) in Python (or print sys.path if you are using Python 2) ? Thanks

[ronaldrobles]

Thank you for your support.

(meddly) ronald@ronald-VirtualBox:~/Loter/python-package$ python

import sys; print(sys.path)

I have also tested in the ROOT environment, and the erro is different:

.

.
Finally I installed a new ubuntu (I forgot to mention I'm working in VirtualBox) and installed all the necessary but without using anaconda.
I obtain the same error "loter.find_lib.LoterLibraryNotFound: Library _loter_wrap.so not found"
its sys. path is:

import sys; print(sys.path)
['', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages', '/home/robles/Loter/python-package']

Thanks for the solution

Hi, sorry for the delay. So I was not able to replicate the problem with Anaconda3-5.2.0, however I was able to replicate it with Anaconda2-5.0.1, I continue to investigate it. I don't know why the behavior would be different depending on Anaconda version.

[gdurif]

What is your Anaconda version ?

[gdurif]

Commit 7aac1aa should fix the problem. You can do a git pull and try to reinstall the package.

[gdurif]

@ronaldrobles could you tell me if the fix works for you ?
