Re: [Python.NET] Python .NET on Windows 8.1

I had the same problem and the following fix in the file runtime/assemblymanager.cs made things work for me. I believe the problem is that on Win 8.1 there seem to be generic types that aren't in a namespace. My patch just skips those and thus prevents a crash. I am not sure whether that is the right way to handle it, but it does fix the crash.

Usually everything worked or at least there was a way to fix it. Right now, there is a situation, that I cannot understand. Since my PC got upgraded from W7 to W8.1 imports stopped working. It seems that something happens on clr module initialization stage, because when I try clr.AddReference("...") python answers: "AttributeError: 'module' object has no attribute 'AddReference'" When debugging with freshly built clr.pyd/Python.Runtime.dll I see that Runtime.Initialize() finishes without exception and clr module methods are added via InitializeModuleMembers(). Yet still, when I run my program clr doesn't work properly and seems like import hooks are not there (breakpoints at AddReference and other methods are not fired). Do you have any pointers for me in this situation? Thank you, Mihhail Maslakov

github migration DONE
by David Anthoff 01 Feb '14

Hi all, I got an ok from Brian and Barton on the github migration, so please consider https://github.com/pythonnet/pythonnet the new home for this project. Please do use the issue tracker to file your ideas, fork the project, create pull requests, test the current version etc. Hopefully we can revive this project! If you would want to volunteer with reviewing stuff etc, please let me know, I myself don't know the codebase well, so right now I'm just trying to get things moving again but it would be good if someone with more familiarity with the code would be active as well. My immediate next goal would be to release a stable version. So my sense is that we should not try to do new features, but first get something out that works again.

When will you release a new build that works on Windows 8.1? I saw some emails in the list archive, but was wondering if anyone had worked out a more concrete plan? Regards, Alan Copeland Agilent Technologies, Inc.

github migration

Alright, I started this now. I created the github organization and the repo. I will also have a stab at migrating the svn history. I've marked the github repo as experimental for now so that it is clear that at this point it is not the official source (yet). I'll keep the list updated as I make progress.

I'm happy to help out with the migration and maintenance if it is decided to go ahead with this. The fork I created doesn't have the history from svn, so I think it would be better to start again with the sourceforge project and pull it into git with all the history and then merge in the various changes already in github. cheers, Tony On Wed, Nov 27, 2013 at 3:21 AM, davidacoder <davidacoder(a)hotmail.com <mailto:davidacoder@hotmail.com> > wrote: I guess my preferred option would be to create a github organization and host the repo there.

In that case the organization can have multiple owners, so the whole thing is also less dependent on one person. If, on the other hand, one of the original maintainers wanted to host it under their account, I would also understand that, i.e. if this is really someone's baby. Finally, I guess the official short name is "pythonnet", right? Or "pythondotnet", like the mailing list alias?

It seems such a natural fit. He would be happy to: 1. Put a link on our "Related projects" page 2. Identify some interesting scenarios and do a blog post 3. Add a dedicated doc page 4. Etc. Subject to: 1. The project is actively maintained 2. Up to date docs 3. It "works" a. Reliable & robust b. Works with PTVS (eg PTVS doesn't crash, .) It would be great if PTVS was able to install python .NET for people (the current install process "copy these dll's" is simple and effective, but a direct install from PTVS would be good. I think we would need to resolve the current situation with the code split between github and sourceforge before we could get the endorsement from PTVS.

ImportError: dynamic module does not define init function (initclr)
by Vinke, Johan 08 Jan '14

08 Jan '14

I tried to get PythonNet working on a Windows 7 machine with Python 2.6.6 installed. My test program is very simple: print "before import of clr" import clr print "done importing clr" When I run the above in Pythonwin, I get this error: ImportError: dynamic module does not define init function (initclr) I have these packages installed (names of the installers are listed here): python-2.6.6.msi (we must use 2.6 because of an application dependency --> Aveva Marine) pywin32-214.win32-py2.6.exe wxPython2.8-win32-ansi-2.8.9.2-py26.exe (and we must use wx......ansi-2.8.9.2..... because it's the only one that works in Aveva Marine 12.1.4) I retrieved this zip file from the PythonNet site (on sourceforge): pythonnet-2.0-alpha2-136-py26.zip And unzipped it and placed the contents of the UCS2 sub-directory (except for the python.exe) in the C:\python26 directory. (Including the clr.pyd and the Python.Runtime.dll). The simple test program I have above is also in the C:\python26 directory. And the PYTHONPATH environment variable contains C:\python26 (and a few other folders/directories). But I can't even get the first real statement - import clr - to work. I apologize if this ends up being a complete newbie question. If you have any ideas on what I'm missing, I would be extremely grateful. Johan Vinke GD-Nassco
