Using numpy/matplotlib - DLL Load Failed
Has anyone encountered this error before? What DLL is being searched for and not found? Any help is greatly appreciated!

I have had tons of issues with python 2.7 and manifest issues that did not occur in 2.6. A short term solution would be to start python from the standard (cpython) python.exe, import your extension libraries that don't play nicely first, then import clr (relying on the late-bound import hook).

I've tried just this - starting up pythonnet.exe and importing pylab, or matplotlib, or numpy as the first import prior to clr. I still get the DLL not found errors. Have you found any other solution? Barton wrote:

Import multiarray first as well. Numpy is doing an import in the __init__ according to what I see here, unless I'm wrong, which is also likely. Lather, rinse, repeat for any additional modules that fail to load.

I have tried, as you mentioned, importing multiarray first. It is a module declared in numpy.core (the filename is "multiarray.pyd") though I keep getting the same error. Any idea what else I might try?

Check to make sure that your pythonpath and system path are the same after you import the CLR. In other words, what are both of these set to when it works, and when it fails. Perhaps Barton has some idea what causes the underlying error. -----Original Message----- From: pythondotnet-bounces+btribble=ea.com@python.org [mailto:pythondotnet-bounces+btribble=ea.com@python.org] On Behalf Of ElMariachi Sent: Wednesday, April 20, 2011 1:46 PM To: pythondotnet@python.org Subject: Re: [Python.NET] Using numpy/matplotlib - DLL Load Failed I have tried, as you mentioned, importing multiarray first.

This is NOT what I have suggested. Use python.exe as installed by python; this gives an unmanaged console app that should be able to import your cpython extensions. THEN import clr; this activates a late-binding of the .NET components. I use this technique successfully to load even the most stubborn (like dynamically manifested wxWindows for 2.7 which has the exact symptom) libraries. I may have time this weekend to do the actual numpy test. WBR, Barton On 4/19/2011 6:22 AM, ElMariachi wrote:
