Re: [Python.NET] Setting PYTHONPATH from code

Hi Sharon, I don't use Python.NET, but I use IronPython and this is a snippet I use to add PYTHONPATH to the sys.path object: I use system variables to do so (for various reasons) at the studio. import sys from System import Environment as sysEnv PythonPath = sysEnv.GetEnvironmentVariable('PYTHONPATH') sys.path.extend(PythonPath.split(';')) Hope this helps.

Hi!

Trying to do as you said:

string script = "import sys\nsys.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,

SAHRON

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, '" + + "')");

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
