Three years ago I wrote a post about my disappointment using SciPy with IronPython. A lot has changed since then, so I thought I’d write a short follow-up post.
To install NumPy and SciPy for use with IronPython, follow the instructions here. After installation, NumPy works as expected.
There is one small gotcha with SciPy. To use SciPy with IronPython, start
ipy with the command line argument
-X:Frames. Then you can use SciPy as you would from CPython. For example.
c:> ipy -X:Frames >>> import scipy as sp >>> sp.pi 3.141592653589793
-X:Frames option you’ll get an error when you try to import
AttributeError: 'module' object has no attribute '_getframe'
According to this page,
The issue is that SciPy makes use of the CPython API for inspecting the current stack frame which IronPython doesn’t enable by default because of a small runtime performance hit. You can turn on this functionality by passing the command line argument “-X:Frames” to on the command line.
