Solver dummy partly out of date #90
Description
The solver dummy seems to be out to date, see https://github.com/precice/python-bindings/tree/develop/solverdummy. It tells users to install the requirements to via
pip3 install --user -r requirements.txt
which seems to fail, see https://precice.discourse.group/t/python-bindings-error-solver-dummy/502/3
The requirements.txt expects pyprecice==2.0. Isn't this too strict and should be pyprecice>=2.0? Do we need the further version digits, i.e., pyprecice==2.0.0.0?
