Question

I am trying to use numpy with ironpython.

When I follow the example in the ironclad documentation, running in a console window, I get this error.

However if I run the same example from an IronPython console within eclipse it seem to work.

>>> import sys; print('%s %s' % (sys.executable or sys.platform, sys.version))
C:\Program Files\IronPython 2.6\ipy.exe 2.6.0 (IronPython 2.6 (2.6.10920.0) on .NET 2.0.50727.3603)

>>> import ironclad
>>> dir()
['__builtins__', 'ironclad', 'sys']
>>> sys.path
['C:\\Program Files\\pythonxy\\eclipse\\plugins\\org.python.pydev_1.5.0.1251989166\\PySrc', '.', 'U:\\Python', 'U:\\Python', 'C:\\Program Files\\IronPython 2.6\\Lib', 'C:\\Program Files\\IronPython 2.6\\DLLs', 'C:\\Program Files\\IronPython 2.6', 'C:\\Program Files\\IronPython 2.6\\lib\\site-packages']
>>> import numpy
>>> x = numpy.zeros(5)
>>> x
array([ 0.,  0.,  0.,  0.,  0.])
>>> 

What is eclipse or PyDev doing differently that is causing this to run?

Answer 1

ipy.exe -X:Frames should work, as _getframe support is optional in IronPython.
