Thank you very much! It will be helpful for us to know which platform (Windows [Mono or .NET] vs Linux) where this is happening.

installing pythondotnet in existing python under windows
by Max Slimmer Oct. 30, 2011

Oct. 30, 2011

I am running python 2.6 under windows and would like to access some .net code. I have downloaded pythonnet-2.0-alpha2-136-py26.zip from source-forge. I can run the python.exe in \python2.6-UCS2 folder and from there import clr, however I want to import and run from my existing python2.6 installation. I put the clr.pyd file in sitepackages and also in DLLs but when I get the following: Python 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import clr Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: dynamic module does not define init function (initclr) >>> I also could use a bit more documentation, I went to Bryan Lloyd's blog and see: Refactored import syntax: now you can use un-prefixed namespace names ( "from System import *") instead of the old "magic CLR module" syntax ("from CLR.System...). The old "CLR." syntax is still supported until 3.0, but now officially deprecated. This was the main compatibility problem with code targeted for IP. I can't figure how to get here! what is the difference between the -UCS2 and -UCS4 folders?
