Multithreading/multiprocessing

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

Calling Python functions/objects forom C# code

Dear mailing list members, I'm new to PythonDotNet, and to integrating Python & C#, and I have to say that I'm 'breaking my teeth' with it; can't find the right examples on the web. The context: I want to use the rich machine learning resources found in python (like scikit-learn) inside a big project written in c#. The problem: can't get started! - haven't even managed to call a function yet. Is there an example or tutorial you can direct me to? Let's say that I want to call the function fib2 from the first example module in python.org, called (fibo.py): ------------------------------------------------------- # Fibonacci numbers module def fib(n): # write Fibonacci series up to n a, b = 0, 1 while b < n: print b, a, b = b, a+b def fib2(n): # return Fibonacci series up to n result = [] a, b = 0, 1 while b < n: result.append(b) a, b = b, a+b return result ------------------------------------------------------- These lines compile J : PythonEngine.Initialize(); PyObject fibmodule = PythonEngine.ImportModule("fibo"); PyObject fibfunc = fibmodule.GetAttr("fib2"); Where do I go from here? How do I send input and get the output into c# array/list? I guess I would need to use PyInt & PyList. How do I do that? Thanks in advance, Avi

running pythonnet on MAC OSX[new to MAC and not not a programmer]

Hi, I want to run python.NET on MAC OSX (Mountain Lion) and since I'm new to MAC/UNIX and I'm not a programmer I naturally turned to the web: *1st : I tried iron python using eclipse with MONO (configuring eclipse iron python interpreter to the mono framework "/Library/Frameworks/Mono.framework/Versions/icy" file) - eclipse doesn't allow this and I got the following error: "No output was in the standard output when trying to create the interpreter info." *2nd : I tried python.NET on XAMARIN : I found this link: http://curtis.schlak.com/2012/01/17/howto-run-pythonnet-on-osx.html I followed all the instructions but it's not clear to me how can I write python in XAMARIN, import clr etc. (I set up the solution as explained in the link above but I'm not sure about the next step). * 3rd try : I found a post on this mailing list : http://mail.python.org/pipermail/pythondotnet/2011-September/001171.html I tried using the original makefile and setup.py (both makefiles) with "sudo setup.py install" and received the following error: "dyld: DYLD_ environment variables being ignored because main executable (/usr/bin/sudo) is setuid or setgid /bin/sh: pkg-config: command not found Traceback (most recent call last): File "setup.py", line 46, in <module> argsDict = pkgconfig('glib-2.0', 'mono-2') File "setup.py", line 32, in pkgconfig raise RuntimeError("An error has occured") RuntimeError: An error has occured " I also tried editing the makefiles and setup.py according to the diff file supplied in the thread but still no success. Is there a makefile/ setup.py file that will work on MAC ? maybe some sort of step by step monkey guide... :-) I appreciate the help, Alon.

Python 3 version of Python for .NET
by Tony Roberts 3 জুন, 2013

3 জুন, 2013

Hi, I've made the necessary changes to the Python for .NET package for it to work with Python 3. What's the best way to get this integrated back into the main project? Can I get access to the svn repo and check it into a branch for peer review and integration? Or should I email someone a patch file? thanks, Tony
