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

FW: [pythonnet/pythonnet] Require at least .NET 4.7.1 (#897)
by Victor “LOST” Milovanov June 26, 2019

FYI From: Benedikt Reinartz Sent: Tuesday, June 25, 2019 11:20 PM To: pythonnet/pythonnet Cc: Subscribed Subject: [pythonnet/pythonnet] Require at least .NET 4.7.1 (#897) For future .NET Standard compatibility and access to some nice simplifications in getting the platform (https://docs.microsoft.com/en-us/dotnet/api/system.runtime.interopservices.… and https://docs.microsoft.com/en-us/dotnet/api/system.runtime.interopservices.… instead of getting the respective information via Python) it would be good to raise our .NET requirement to 4.7.1 or 4.7.2. Would this pose serious problems for anyone? Upgrading the runtime should usually always be possible and we already require at least 4.0, I think in some cases even 4.5. — You are receiving this because you are subscribed to this thread.

AppVeyor account might make it worth it - vote next meeting - development resources for the future? - performance improvements - missing features - maintenance - merging QuantConnect fork into main repo? Benedict will review QC's fork with Jared (jared(a)quantconnect.com) and merge or suggest changes - Benedict will trim admin rights to only active committers - Please use issues for proposed work to be done and use "Epic" tag. suggested: - .NET core work - Python 3.8 work - other refactoring or features - Victor ( lostfreeman(a)gmail.com) will make PRs for key parts from his fork - Benedict suggested that we should move as much work as possible into the main repo - concern from QuantConnect that their velocity might be impacted - mitigated by keeping work flowing from QC fork to pythonnet/pythonnet?

QuantConnect's questions for the community: - Who are you? Where are you based? Are you an individual or a company? - Out of 10, 1 being a low priority, 10 being critical to survival, where would you place PythonNet's priority in your organization? - Are you winning to sponsor the project to hire a full-time developer? (e.g. 10 companies, $500 ea). - Order the following priorities for PythonNet future from first is most important: *Speed, Stability, Python Version Support, Supported Features (e.g. named args), Documentation, Promotion/Website, **Support for **Community Questions* ᐧ On Tue, Jun 11, 2019 at 8:31 AM <pythondotnet-request(a)python.org> wrote: > Send PythonDotNet mailing list submissions to > pythondotnet(a)python.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://mail.python.org/mailman/listinfo/pythondotnet > or, via email, send a message with subject or body 'help' to > pythondotnet-request(a)python.org > > You can reach the person managing the list at > pythondotnet-owner(a)python.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of PythonDotNet digest..." > > > Today's Topics: > > 1.

Retiring Python 2.7
by Victor “LOST” Milovanov June 14, 2019

June 14, 2019

Python 2.7 end of life is set to Jan 1st 2020, which is just a bit over 6 months now. https://pythonclock.org/ Major packages, like numpy are planning to drop support too. I think we should have some kind of plan to retire Python 2.x support in Python.NET. First of all, it would be good to know if there are anyone actually using Python 2.7 via Python.NET, and what is your plan going forward past EoL. Regards, Victor Milovanov
