Hi, I've not had problems running SimPy samples with IronPython. In fact, I copied the MachineShop sample from their page and added it to a Python project in VS2013 (you need to have PythonTools for Visual Studio installed to do this). I could run that Python project without problems. I also ran the model within our own environment in which I integrated IronPython-based script execution recently. I could run the model without problems. Of course you have to do some imports first: import sys sys.path.append(r"C:\Program Files (x86)\IronPython 2.7\Lib") sys.path.append(r"C:\somepath\simpy-3.0.3")
Btw, I've also created a .NET port of SimPy, named SimSharp, which you might be interested in: https://github.com/abeham/SimSharp It's not a 1:1 port, but I tried to port the basic concept of using an iterator to model a process.

April 2014 12:03 An: ironpython-users@python.org Betreff: [Ironpython-users] SymPy and IronPython 2.7.4 Hello, I have embedded IronPython 2.7.4 into a .NET 4.0 C# application. I can enter and run scripts and I also have an interactive console. It's working great and I have no issues... until I tried to use SymPy. I've asked for help from the SymPy people but they don't have any experience with IronPython. I have a subfolder called PythonLib into which I have copied the 2.7 standard libraries. Importing from these works: ======================================================== >>>import xml.dom >>> ======================================================== So I have copied SymPy into PythonLib as well (e.g. I have \PythonLib\sympy\__init__.py). Here is the first issue: ======================================================== >>>import sympy Traceback (most recent call last): File "<string>", line 1, in <module> File "C:\Users\Andy\Documents\ADScript\PythonLib\sympy\__init__.py", line 32, in <module> File "C:\Users\Andy\Documents\ADScript\PythonLib\sympy \core\__init__.py", line 8, in <module> File "C:\Users\Andy\Documents\ADScript\PythonLib\sympy\core\expr.py", line 7, in <module> File "C:\Users\Andy\Documents\ADScript\PythonLib\sympy\core\evalf.py", line 27, in <module> File "C:\Users\Andy\Documents\ADScript\PythonLib\sympy\core\containers.py", line 14, in <module> File "C:\Users\Andy\Documents\ADScript\PythonLib\sympy\utilities\__init__.py", line 17, in <module> File "C:\Users\Andy\Documents\ADScript\PythonLib\sympy\utilities\timeutils.py", line 11, in <module> File "C:\Users\Andy\Documents\ADScript\PythonLib\sympy\core\compatibility.py", line 110, in u TypeError: unicode_escape_decode() takes no arguments (1 given) ======================================================== I can't find any description of what unicode_escape_decode does. It seems to be a built-in function? In general SymPy is passing a string to it to be decoded so it appears to make sense that the function has an argument. I've worked around this with the following: ======================================================== >>>import codecs >>>def my_unicode_escape_decode(x): ... return x ... >>>codecs.unicode_escape_decode = my_unicode_escape_decode ======================================================== Now I get attribute errors. Here is the result of running several imports. Can anyone please give me some pointers as to what might be the issue? I'm thinking it is something to do with my environment or the way I am embedded IronPython. Thanks!
