PyESAPI: Getting Started

I am trying the first line of the getting started workshop script, but right away I am getting an error. The notebook says "Create one instance of the eclipse scripting application" by which I am assuming (could this be clarified?) they mean to open external beam planning and then open tools>scripts.

This is what I have done and I run

import pyesapi
import atexit
app = pyesapi.CustomScriptExecutable.CreateApplication('python_demo')

but then get the error

TpsNetInitializationException: [10/8/2021 10:46 AM] TPS.NET ApplicationNonAppFrame: Initialization FAILED. Here is the initialization log:
[10/8/2021 10:46 AM] TPS.NET ApplicationNonAppFrame: START initializtion, m_initCounter=1, status=NotInitialized.
[10/8/2021 10:46 AM] TPS.NET ApplicationNonAppFrame: Only one Application object is supported at a time.

   at VMS.TPS.Common.Model.API.Application.CreateApplicationCommon(String scriptName, Func`2 createExecutionGuardFunc)

So I assume this means that the scripting application is an instance too many and needs to be closed, so I close out and run the same, but again I get the same error. When I run without ARIA or eclipse open in the background, I instead get the error

app = pyesapi.CustomScriptExecutable.CreateApplication('python_demo')

I think the script must be having trouble finding the Varian dlls, however these are stored in C:\Program Files (x86)\Varian\RTM\15.6\esapi\API which is in my PYTHONPATH variable.

you might try looking into current ESAPI version which is in init.py file of your pyesapi package:

ESAPI_PATH = os.environ.get('ESAPI_PATH')

if ESAPI_PATH is not None:
    # optionally set ESAPI_PATH env var with location of DLLs
    sys.path.append(ESAPI_PATH)
else:
    # do some soul searching
    rpaths = [os.path.join("esapi", "API"), "ExternalBeam"]
    # versions = ["15.5", "15.6"] # this was originally in the file I changed it to 17.0 version to avoide doubles
    versions = ["17.0"]
    base = os.path.join("Program Files (x86)", "Varian", "RTM")
    drives = ["C:", "D:"]  # Could potentially list local drives, but Eclispe should be on C or D

For anaconda the file location is sth like:
...\anaconda3\envs\pyesapi38\lib\site-packages\pyesapi

The other question would be if you have .NET installed on your system?
