Install crystalpy

You install in the usual way. This is working for me:

# proxy 
export all_proxy=http://proxy.esrf.fr:3128/

#clean
rm -rf CRYSTALPY_TEST

# create temporary test directory
mkdir CRYSTALPY_TEST
cd CRYSTALPY_TEST

#create virtual environment
virtualenv -p /usr/bin/python --system-site-packages test1env

#activate virtual environment
source ./test1env/bin/activate

#install
pip install http://ftp.esrf.eu/pub/scisoft/Oasys/pip/xraylib-3.1.tar.gz
pip install mpmath
pip install crystalpy


#test 
cd ~
python CRYSTALPY_TEST/test1env/lib/python2.7/site-packages/crystalpy/examples/Si111_simple.py

Notes

• Works for python2 and python3. If you are using python2 do not run examples/Si111.py that uses srxraylib and has problems in python2.
