Multithreading/multiprocessing
by Alan Macdonald 5 মে, 2025

Hello, has anyone successfully used multithreading or multiprocessing with Python.Net? I tried to multi-thread from the .Net side and the Python.Net libraries seem to have issues in the RunScript method. I had to take an implementation off the web of that method because the shipped method doesn’t seem to work. I then had a working multi-processing example from CPython that I tried from Python.Net but it gives an error 'module' object has no attribute 'argv' When trying to create a process pool by executing the line pool = Pool(processes=4) Is it possible to do multithreading or multiprocessing with Python.Net? Thanks, Alan

Can anyone tell me how to cast or Convert (or use a TryGet, or As whatever...), a PyObject (a Python function), to a C# RoutedEventHandler? The Python function: def OnStartButton(sender,args): #do stuff pass Thanks Steve ___________________________________________________________________________ This e-mail is confidential and is for the addressee only.

Passing a C# DateTime object to a Python script
by Ian Hannah 8 জুন, 2018

8 জুন, 2018

Hi, I have a simple python script: def test(datetime_or_doy): print datetime_or_doy.strftime('%m/%d/%Y') and I am using Python for .NET to try and call this method as follows: dynamic np = Py.Import(@"pvlib"); double d = np.irradiance.test(DateTime.Now); and I get the error: Python.Runtime.PythonException: 'AttributeError : 'DateTime' object has no attribute 'strftime'' Clearly I need to pass a Python datetime object from the C# code but how do I do that? Thanks Ian

Finalizers and proper dereference of CPython objects
by Tom Unger 8 জুন, 2018

8 জুন, 2018

PythonException, PyObjecdt, PyScope have finallizers defined as: ~PyObject() { // We needs to disable Finalizers until it's valid implementation. // Current implementation can produce low probability floating bugs. return; Dispose(); } So the finalizer does not call dispose. Does this mean that I must explicitly Dispose all such objects to ensure no memory leaks? Thanks, Tom
