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!
