Cannot import to Python

[asnaumoff@…]

Hi!

I use Mac OS Mojave and python 3.6.8.

Cannot create OMCSessionZMQ. I installed OM 1.13 and ompython via

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

I get the following error:

from OMPython import OMCSessionZMQ
omc = OMCSessionZMQ()

---------------------------------------------------------------------------

}}} says nothing :(

You need to set the PATH environment variable or OPENMODELICAHOME to point to the installation.
