[Python.NET] homebrew pythonnet, versus pip install --pre pythonnet

It has been a while since I've had to deal with this, but make sure that your assembly is in the system path and/or pythonpath if it is not registered in the GAC.

Hi All,

Amazing library, first of all!

I am experimenting with integrating ipython / numpy / pandas for interactive data analysis with our large existing C# codebase. We are using the Anaconda 2.0 release from ContinuumIO. With `pip install -pre pythonnet`, everything goes as expected (great!)

However, when I build from source (in VS2013), point my PYTHONPATH to the clr.pyd and Python.Runtime.dll that results from the build, and run my ipython, I can do `import clr` and `ref = clr.AddReference("assemblyname")`, but I cannot load any modules within this assembly. I get a `ImportError: No module named ...` Furthermore, if I try to do ref.ExportedTypes, I get a `FileNotFoundException: Could not load file or assembly ...` where it cannot find an assembly that is referenced by the original assembly. There must be some broken loading going on... Any thoughts why this might have different behavior than what I install via PyPI (https://pypi.python.org/pypi/pythonnet/2.0.0.dev1)? Or, hints on how to debug?
