Multithreading/multiprocessing
by Alan Macdonald May 5, 2025

May 5, 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

Struggling with a library
by Juanma Belda March 27, 2012

March 27, 2012

Dear all, I'm a newbie in pythonnet and I have the following problem. I am trying to load an assembly from a .dll file. Currently I am running the trials over Windows XP and python 2.6.5 and pythonnet version 2.0 alpha 2 On my computer there is no problem on loading the library. However in another computer (notebook) with the same installation (the library in the path etc) the system fails to do the AddReference. However if I ask for findAssemblies the system is able to find it. I can add the Reference to the test dll that come with the pythonnet. I was assuming a mismatch on the .net versions, but then: why can l loaded from some computers and not from some others? Kind regards, -- Juanma

import clr_2, import clr_4 vs import clr
by Liam Corrigan March 23, 2012

March 23, 2012

Hi guys, I've been using python .NET 2.0 in python 2.7.2 successfully for some time now and have also used the .NET 4.0 version, but of course I need to replace the clr.pyd and Python.Runtime.dll with the .NET 4.0 versions. Although most of my 2.0 libs work over the 4.0 version, there is one in house library targeted against .NET 2.0 that will not, without some awkward hacks. I need to be able to call into libraries written against both .NET 2.0 and 4.0, as separated calls - ideally, I'd like to have things such that I can operate in a python script something like this: import clr_2 import clr_4 clr_2.AddReference("MyDOTNET_2.0_BasedLib") clr_4.AddReference("MyDOTNET_4.0_BasedLib") Are there any settings in the source build that I can do, to kick out two separate clr.pyd and Python.Runtime.dll's with new names and matching .NET version support?
