Dear Jan,

Many thanks for sharing with us your code and answering to our questions.
I have successfully installed your code

and then tried to run the contact1.py example and I am having this error:

The operating system is ubuntu 18.04

Thank you in advance.

With kind regards,
Kostas

Please next time put copy-pasted code / message, not screenshots

I was not able to reproduce the error. Have you done any changes?

Thank you for the quick response.
The only change that I can see is the one that I did during installation.

So first i tried with python 3:
sudo add-apt-repository ppa:yade-users/external sudo apt-get update
and then with yade prerequisites:
sudo apt install cmake git freeglut3-dev libloki-dev libboost-all-dev fakeroot \ dpkg-dev build-essential g++ python3-dev python3-ipython python3-matplotlib \ libsqlite3-dev python3-numpy python3-tk gnuplot libgts-dev python3-pygraphviz \ libvtk6-dev libeigen3-dev python3-xlib python3-pyqt5 pyqt5-dev-tools python3-mpi4py \ python3-pyqt5.qtwebkit gtk2-engines-pixbuf python3-pyqt5.qtsvg libqglviewer-dev-qt5 \ python3-pil libjs-jquery python3-sphinx python3-git libxmu-dev libxi-dev libcgal-dev \ help2man libbz2-dev zlib1g-dev libopenblas-dev libsuitesparse-dev \ libmetis-dev python3-bibtexparser python3-future coinor-clp coinor-libclp-dev \ python3-mpmath libmpfr-dev libmpfrc++-dev

but was not able to compile the code with the command make all.

then I executed (python instead of python3):
sudo apt install cmake git freeglut3-dev libloki-dev libboost-all-dev fakeroot \ dpkg-dev build-essential g++ python-dev ipython python-matplotlib python-mpi4py \ libsqlite3-dev python-numpy python-tk gnuplot libgts-dev python-pygraphviz \ libvtk6-dev python-numpy libeigen3-dev python-xlib python-pyqt5 pyqt5-dev-tools \ python-pyqt5.qtwebkit gtk2-engines-pixbuf python-argparse python-pyqt5.qtsvg \ libqglviewer-dev-qt5 python-pil libjs-jquery python-sphinx python-git python-bibtex \ libxmu-dev libxi-dev libcgal-dev help2man libbz2-dev zlib1g-dev python-minieigen \ libopenblas-dev libsuitesparse-dev libmetis-dev libopenmpi-dev openmpi-bin \ openmpi-common python-bibtexparser python3-future python-future python-gts \ coinor-clp coinor-libclp-dev python-mpmath libmpfr-dev libmpfrc++-dev

and the code compiled successfully but then I cannot run the example.

[stranskyjan]

I don't know. As I said, I cannot reproduce the problem.

Also the code currently works only with Python 2, don't know if installing the python3-related stuff can be the problem

Thanks for replying.
I will keep trying and keep you updated if I will manage to succeed.
