OpenModelica 1.16.0-dev.beta1-64bit OMPython Install Problem

[anonymous]

Following the directions at ​https://github.com/OpenModelica/OMPython
Windows 10
Python 3.7.9
Latest pip 20.2.3
Just downloaded OpenModelica Wednesday, September 30.

c:\Program Files\OpenModelica1.16.0-dev.beta1-64bit\share\omc\scripts\PythonInterface>python -m pip install -U
ERROR: You must give at least one requirement to install (see "pip help install")

Command Prompt - Regular user or Administrator - same result.

It was working with 1.14.

This is top priority. @sjoelund.se, could you have a look, please?

I think is Adeel or Arun that know how OMPython installs on Windows.

The path is wrong, you should go to the following location "C:/Program Files/OpenModelica1.16.0-dev.beta1-64bit/share/omc/scripts/PythonInterface/OMPython" and open the command prompt in administrator mode and do the following

>>> cd C:/Program Files/OpenModelica1.16.0-dev.beta1-64bit/share/omc/scripts/PythonInterface/OMPython 
>>> python setup.py install

OR

since you already have pip installed, just from the command prompt run

>>> pip install OMPython

This should also work.

Still not there yet. "help(OMPython" works as before. Then do:

import OMPython
from OMPython import OMCSessionZMQ
omc = OMCSessionZMQ()

Retargeted to 1.17.0 after 1.16.0 release

@anonymous, have you tried with a more recent version?

[Andreas Heuermann]

Is there a chance you just missed the . (dot) in

c:\Program Files\OpenModelica1.16.0-dev.beta1-64bit\share\omc\scripts\PythonInterface>python -m pip install -U

it should be

c:\Program Files\OpenModelica1.16.0-dev.beta1-64bit\share\omc\scripts\PythonInterface>python -m pip install -U .

But I installed OMPython a week ago (v1.17-dev and v1.18-dev) and it worked fine for me running it from Python 3.8 from Anaconda.

It could also be that you will need Python 3.8 (you seem to be using 3.7) for some function to open dll's.

Retargeted to 1.18.0 after 1.17.0-dev.beta2 release
