I'm not sure about the error message but unfortunately 1.x doesn't expose Dispose as __exit__. That's been fixed in 2.0.

Hi, I am trying to call MPI.Net from IronPython 1.1.1 in the following script. The problem is IronPython automatically converts my MPI.Environment() object into a tuple type, so that the object cannot be disposed at the end of with statement. the following is what I did: 1) write a __future__.py containing the following 2 lines: division=1 with_statement=1 2) run my script like: ipy.exe -X:Python25 pi.py Got error here: Traceback (most recent call last): File d:\tools\IronPython-1.1.1\pi.py, line 19, in Initialize AttributeError: 'tuple' object has no attribute '__exit__' ERROR: MPI.Environment not finalized. Please call Dispose() on your MPI.Environment object. Can you tell me what's wrong with the script? can I avoid to the conversion from MPI.Environment object to tuple? Thanks, # This is a IronPython program to calculate PI using MPI.Net. # Usage (For IronPython 1.1.1): # ipy.exe -X:Python25 pi.py from __future__ import with_statement import sys import clr import System sys.path.append("C:\Program Files (x86)\MPI.NET<http://MPI.NET>\Lib") clr.AddReferenceToFile("MPI.dll") import MPI with MPI.Environment(argarrayref) as mpienv: n=100 Liwei
