    Hi all
    I have an application using docplex.cp. I am using a full development license for this.

    I have built a large application and everything is running well

     

    But when I try to run this application remotely (using a package called Ignition, the application tries to use the Community edition of docplex which I had used previously

    How can I make Community edition go away?

    BTW the "calling app" uses a subprocess call as below:

    pythonPath = r"C:\Users\Ross\source\repos\PythonApplication1\env\Scripts\python.exe"
    scriptPath     = r"C:\Users\Ross\source\repos\PythonApplication1\main.py"
    result = subprocess.check_output([pythonPath, scriptPath], stderr=subprocess.STDOUT)



    Thanks

    Hi Ross,
    I don't know Ignition (and may give it a try), but I would give it more information about Python modules location.
    Have you already tried to prepend the python environment directory location (e.g. the venv where full cplex is installed) into `pythonPath`  ?

    It is a licensing issue

    Apparently a separate run-time license is required

    Thanks

    I have a Cplex Optimization Studio (COS) installed. It holds a full development license.
    I have multiple Python environments, with docplex module (with Community edition by default).
    In order to make one of these Python env benefit from my COS license, I activate this env and run `python setup.py` from <COS_INSTALL_DIR>/python
    then it can solve large models.
    I've never heard about a runtime license. 
    Hope this helps

    Thank you

    That's interesting. IBM support advised that I needed run-time license, & dev version was for development only. Many requests for run-time license price == no response.

    I don't know how to set up 'multiple python environments'. I have only set up a python environment from within Microsoft Visual Studio

    Can I use the environment set up by MS Visual Studio?

    You can very likely use a Python environment set up by MS Visual Studio, as long as you can locate it.
    Basically a Python env is a directory that provides a consistent Python distribution, that can be enriched to fit a given usage.
    It can come from a pure installation, Conda, Poetry... , be local, containerized, remote...
