Hi!

 

Tried after your mail.

 

Does not change…

 

Regarding the PYTHONPATH:

 

I change it with code (System.Environment.SetEnvironmentVariable("PYTHONPATH",PathValue)) and it does not help me at the first run of the application. (I am getting Null value from the ImportModule)

But, after closing the application & opening it again it works (event if changing the PYTHONPATH in the code) with the PYTHONPATH that was set in the run before…

 

Any Idea?

 

Thanks,

 

SHARON

Hi!

 

Trying to do as you said:

 

            string script = "import sys\nsys.path.insert(0, '" + modulePath + "')";

Have you tried using a semi colon instead of new line?

            string script = "import sys; sys.path.insert(0, '" + modulePath + "')"; 

            IntPtr pythonLock = PythonEngine.AcquireLock();

 
            PythonEngine.RunSimpleString(script);
            PythonEngine.ReleaseLock(pythonLock);

 

And then:

            IntPtr gs = PythonEngine.AcquireLock();

 
            pyportal = PythonEngine.ImportModule(moduleName);
            if (pyportal == null)
            {

                                …

                            }

           …

 

I got Null value from the ImportModule.

 

When setting the PYTHONPATH manually in the system variables with the “modulePath” and opening the VS is works.

 

Any idea? 

 

Thanks,

Hi Sharon,

 

What do you want to achieve with this? If you want to provide path for loading your own modules you can change the sys.path value by e.g. running a 'initialization' script with 

 

import sys

sys.path.insert(0, 'your/own/path')

 

You can build up the script above in C# by inserting the path you need and then performing e.g. RunSimpleString(<script>) like

 

string script = "import sys\nsys.path.insert(0, '" + <variable_with_path> + "')");

IntPtr pythonLock = AcquireLock();

RunSimpleString(script);
ReleaseLock(pythonLock);

 

Does this help?

Hi!

 

Can someone tell me how to set PYTHONPATH variable in code when working with Python.Runtime.dll without changing the value in the system variables before.

 

Thanks

 

SHARON
