PythonNet on Cygwin
by Nikhil Garg 21 Jun '17

21 Jun '17

Hi Guys, I was wondering if anyone knows how to make Python for .Net work on cygwin installation of python. I have been looking around and find a mixed bag of information. If anyone knows of the working version of Python for .Net and its dependency, I would appreciate if you could share it with me. Currently, I am using a generic windows version and it works just fine, but I need it to work on Cygwin version of python. I appreciate any helpful replies. Thanks, Nikhil

cx_freeze and python.net
by Boris Burdin 22 May '17

Hello everybody, I'm trying to build a python.net application using cx-freeze . Once the application is built, I put in my final folder the Python.Runtime.dll. but it stil doesn't seem to work . Actually, when I run the .exe file, nothing is happening. So, I wonder if there were something else to do, another dll to put in the folder, or any option to use with cx_freeze when building the application ? i would be very grateful if you could help me on this matter .. Thanks in advance, Boris

pythonnet appdomain(s)
by Adam Klein 07 Sep '16

Hello, Is there a design reason that pythonnet loads C# assemblies into its own AppDomain rather than establishing a separate AppDomain? It would be useful for instance when developing in C# in parallel with writing python code (say, in the ipython REPL) to be able to reload C# assemblies dynamically. Also, we've found it useful in Initialize() to enable shadow copying, to prevent file locking, ie internal static void Initialize() { ... AppDomain domain = AppDomain.CurrentDomain; // prevent file locking domain.SetShadowCopyFiles(); domain.SetShadowCopyPath(null); Although these are deprecated methods, and really it should be establishing a new AppDomain as above.

Python class instance from C#
by Denis Akhiyarov 06 Jan '15

Does anyone have an example of using Python.NET in embedding scenario for creating an instance of a Python class/object, possibly with arguments passed to __init__() and then using this instantiated class to call its methods? The workaround for me right now is calling Python wrapper function that returns new instance of this class. I have an example that does NOT work for me: IntPtr pyobj = default(IntPtr); IntPtr u_name = Runtime.PyUnicode_FromString(ModuleName); IntPtr module = Runtime.PyImport_Import(u_name); IntPtr pyclass = Runtime.PyObject_GetAttrString(module, ObjectName); if (Runtime.PyCallable_Check(pyclass) == 1) { pyobj = Runtime.PyObject_CallObject(pyclass, pyargtuple); } IntPtr inst = Runtime.PyObject_Call(pyobj, IntPtr.Zero); PyObject result = new PyObject(inst); return result;
