Thanks all for the replies! I've also been in touch with the folks at Enthought, and they provided the idea that has led to me posting a question at StackExchange: http://stackoverflow.com/questions/13222393/compiling-pythonnet-net-to-work-... I'm pretty sure my bit-to-bit issue is accounted for. I've also used the numpy from EPD in the same python I'm using for pythonnet and that has no problems. As far as the UCS issues, I was only able to build the pythonnet project as UCS-2, if I changed that string to UCS-4 the build crashed... maybe something on windows? Thanks for helping!

Make sure you are installing the correct "bitness" of numpy for your install of python (64-bit to 64-bit, 32-bit to 32-bit).

That error suggests issues with your path or current directory. Multiple or incompatible dynamic libraries etc. in the path. Generally speaking, pythonnet does work with numpy. Something specific is wrong, loading a dll in a low level manner that msvc is upset.

Hello,

As mentioned in the other thread, I have built pythonnet with VS2012 for a 64-bit Python installation and using .NET 4 assemblies. Things seem to work well.

However, I just tried to `import numpy` and all hell broke loose... the reason I pursued pythonnet was because I thought it would allow me to use the pure CPython modules without needing to rely on any of the modified versions built for IronPython. Below is the PowerShell output from starting EPD and importing numpy and starting pythonnet python.exe and importing numpy.

This is not a lot of information, but maybe someone has some ideas on how to troubleshoot?

Thank you, john
