[degapifa]

after the installation, when i start tutorial.sh
I have this problem:
Traceback (most recent call last):
File "/usr/local/pyinteraph//pyinteraph", line 162, in
from libinteract import libinteract as li
File "/usr/local/lib/python2.7/dist-packages/libinteract/libinteract.py", line 1, in
import MDAnalysis as mda
ImportError: No module named MDAnalysis
but, i have MDAnalysis installed.

Hi,
that depends on how MDAnalysis is available on your system - can you give me some details on your Python installation and what changes you made in the tutorial script file? What do you get if you run python -c 'import MDAnalysis'

Thank you for your answer.
if i run run python -c 'import MDAnalysis' in terminal, nothing is displayed. (i click 'send' and go in a new line)
I use Ubuntu, so i have Python 2.7.17 and Python 3.6.9.
in tutorial.sh i have modified the frist two lines accordingly to my installation.
So i used this command:
python setup.py install --home=test
And i modified in this way:
export PYTHONPATH=$PYTHONPATH:/home/user/Scrivania/pietro/pyinteraph-master/test/lib/python/libinteract
export PYINTERAPH=/home/user/Scrivania/pietro/pyinteraph-master/test/pyinteraph
export PATH=$PATH:$PYINTERAPH.
I tried to verify the MDAnalysis version, with this command: python -c 'import MDAnalysis as mda; print(mda.version)' and it is: 0.20.1

1. Notice PyInteraph needs MDAnalysis 0.7.6 which is a bit old and not super easy to install nowadays. We're working on a version that will run on the latest MDAnalysis and Python 3, that will certainly be easier to support
2. About your second error, it's a bit strange - have you changed something else in your build system? I recommend you restart from scratch and re-building the libraries (by running setup.py)
