Executing the following:

virtualenv --system-site-packages -p python3 venv
. venv/bin/activate
git clone https://github.com/pymor/pymor.git
cd pymor
git checkout qt_py
pip install -r requirements.txt
pip install -r requirements-optional.txt
cd src
echo $PWD > "$(python -c 'from distutils.sysconfig import get_python_lib; print(get_python_lib())')/pymor.pth"
python setup.py build_ext --inplace
cd pymordemos
./thermalblock_gui.py

gives the following error:

Traceback (most recent call last):
  File "./thermalblock_gui.py", line 46, in <module>
    from Qt import QtWidgets
ModuleNotFoundError: No module named 'Qt'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "./thermalblock_gui.py", line 48, in <module>
    raise QtMissing()
pymor.core.exceptions.QtMissing: cannot visualize: import of Qt bindings failed

I am obviously missing something...

Following @sdrave suggestions,

virtualenv -p python3.6 venv
. venv/bin/activate
pip install git+https://github.com/pymor/pymor@qt_py
git clone https://github.com/pymor/pymor.git
cd pymor/src/pymordemos
git checkout qt_py
./thermalblock_gui.py

yields
