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
Attendees: Victor, Benedikt, Mark
Agenda:
Review previous action items:
Victor will continue working on PRs for breaking changes that could land for 3.0
Amos will continue working on porting performance improvements to master
"We'll try to come up with a concrete roadmap for the 3.0 release in one of the next biweekly meetings."
Python 3.9 on the mailing list
Github Discussions feature
https://github.com/pythonnet/pythonnet/pull/1402 <https://github.com/pythonnet/pythonnet/pull/1402> blocked by issue #1412 <https://github.com/pythonnet/pythonnet/issues/1412>
Notes
Release candidate for 3.0
next step is a preview build
need to groom 3.0 milestone
need to decide on breaking API changes for 3.0 - last chance to break API
python wheel build needs to be fixed
can't run 32-bit in CI because dotnet clr doesn't support 32-bit
Unity does not support 32 bit
would be nice if we can run ARM in CI
Python 3.9 is not supported on 2.5 branch
if anyone wants to work on this they are welcome to do so (on 2.5 branch) but we have no plans to support on 2.5
we know it crashes, non-trivial to debug
support will come in 3.0 (master branch)
Github Discussions
let's wait and see
Action Items:
Victor will go through issues to select ones for 3.0
Victor will work on memory leaks
Benedikt will look into running 32 bit builds in CI
Mention we do not officially support 32 bit yet
