Here is my recipe that works for Anaconda2 (date, Sept. 2019) and ir worked
perfectly for Ubuntu18 and conda version (4.7.11)

1. Download anaconda from
https://www.anaconda.com/distribution/#download-section
2. chmod +x Anaconda2-2019.07-Linux-ppc64le.sh
2.1  -> change directory to /home/$USER/anaconda

3. After anaconda successfully installed, define PATH to include
/home/$USER/anaconda/bin 

4. install some minor dependencies reported elsewhere
4.1   conda update conda
4.2   conda install cmake lxml swig  
4.3   conda install conda-build   
4.4   conda install patchelf       


5. Download openbabel (last release) from github and compile with anaconda
dependencies:
5.1 git clone https://github.com/openbabel/openbabel
5.2 cd openbabel
5.3 mkdir build
5.4 cd build
5.5  cmake .. -DPERL_BINDINGS=ON -DPYTHON_BINDINGS=ON -DRUN_SWIG=ON
-DCMAKE_INSTALL_PREFIX=~/anaconda
-DPYTHON_INCLUDE_DIR=~/anaconda/include/python2.7
-DCMAKE_LIBRARY_PATH=~/anaconda/lib -DSWIG_DIR=~/anaconda/share/swig/3.0.21/
-DSWIG_EXECUTABLE=~/anaconda/bin/swig
-DPYTHON_LIBRARY=~/anaconda/lib/libpython2.7.so

## Please, verify files are in the correct path !!

6. Include variables into .bashrc
export PATH=$PATH:/home/$USER/anaconda/bin
export BABEL_LIBDIR=/home/$USER/anaconda/lib/openbabel/2.4.90
export BABEL_DATADIR=/home/$USER/anaconda/share/openbabel/2.4.90
export
PYTHONPATH=$PYTHONPATH:/home/$USER/anaconda/lib/python2.7/site-packages

*
## Important!!!. *

python2.7>  from openbabel import openbabel as op
python2.7>  from openbabel import pybel as py

*Be aware "import openbabel" is already deprecated*

Hope it works!!
