OMPython

OMPython is a Python interface that uses ZeroMQ or CORBA (omniORB) to communicate with OpenModelica.

Dependencies

Using ZeroMQ

• Python 2.7 and 3.x supported
• PyZMQ is required

Using omniORB

• Currently, only Python 2.7 is supported
• omniORB is required:
  • Windows: included in the OpenModelica installation
  • Linux: Install omniORB including Python 2 support (the omniidl command needs to be on the PATH). On Ubuntu, this is done by running sudo apt-get install omniorb python-omniorb omniidl omniidl-python

Installation using pip is recommended.

python -m pip install -U https://github.com/OpenModelica/OMPython/archive/master.zip
