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

Hi! Can someone tell me how to set PYTHONPATH variable in code when working with Python.Runtime.dll without changing the value in the system variables before.

IronPython Embeddied .NET 4.0, how to transfer object from C# into Ironpython and back again
by riscy00 17 মে, 2012

17 মে, 2012

I'm learning more about data/object transfer between C# and ironpython (under embedded within NET4) I have class object instance containing Dictionary<T> implementation with data such as "XDATA:67, YDATA:12,ZDATA:66" I also have test.py filename which is loaded into C#'s IRONPYTHON (using var and dynamic method). I was curious how to transfer data within the class object into Python (reference class or a copy?) which do various processing (ie ZDATA=YDATA+XDATA) and then return result within the same class (rather than value) Is this possible, if so please demonstrate code example in C# and python. How to make sure both Dictionary within C# is the same as python? The whole aim is to pass object instance into python and do operation task using object data and then pass data back into class and make it available to return object back to the C# for further processing. I wondered if this can this be done by mean of reference (rather than copy?, faster and more compact this way perhaps). -- View this message in context: http://python.6.n6.nabble.com/IronPython-Embeddied-NET-4-0-how-to-transfer-… Sent from the Python - pythondotnet mailing list archive at Nabble.com.
