@solospirit: You are doing illegal things with Python and believe me - it bites back :)
Remember that in Python you cannot just import modules (.py) just from arbitrary paths, unless you are using importlib or sys.path. Hence here is the correct workflow using sys.path: *Microsoft (R) Roslyn C# Compiler version 1.2.0.60425* *Loading context from 'CSharpInteractive.rsp'.* *Type "#help" for more information.* *> #r "C:\Python\Python27_32b\Lib\site-packages\Python.Runtime.dll"* *> using Python.Runtime;* *> dynamic sys; using (Py.GIL()) { sys= Py.Import("sys"); }* *> using (Py.GIL()) { sys.path.append(@"C:\Users\denis.akhiyarov\Downloads") ; }* *> dynamic testmodule; using (Py.GIL()) { testmodule = Py.Import("network2"); }* *> testmodule.Network* *[<class 'network2.Network'>]* Perhaps this should be documented here: https://github.com/pythonnet/pythonnet/wiki/pythonnet-troubleshooting-wiki-on-Windows Thanks, Denis On Mon, Sep 26, 2016 at 8:40 AM, solospirit <solospi...@sohu.com> wrote: > Hi, > > > I'm using windows 7 64bit + Visual C#2012 to develop WinForm 32bit > application with .Net Framework 4.0.
