IronPython invocation from C# (with SciPy) fails with ImportException: “No module named mtrand”

Question

I have a python library I am trying to use via IronPython (v2.7 RC1 [2.7.0.30]) invocation from C# application. The library uses NumPy and SciPy quite extensively, which

Answer 1

Not the best soultion, but its works for me:

import sys
sys.path.append(r'c:\Program Files (x86)\IronPython 2.7')
sys.path.append(r'c:\Program Files (x86)\IronPython 2.7\DLLs')
sys.path.append(r'c:\Program Files (x86)\IronPython 2.7\Lib')
sys.path.append(r'c:\Program Files (x86)\IronPython 2.7\Lib\site-packages')

import clr
clr.AddReference('mtrand.dll')

import numpy
import scipy

print numpy.__version__
print scipy.__version__

I hope it helps.

Answer 2

I found that, in my ActivePython V2.7.0.2, this works:

sys.path.append(r'C:\\Examples')
import examples

(assuming examples.py is in C:\Examples). This doesn't (without the r):

sys.path.append('C:\\Examples')
import examples

Because I get this:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named examples

Conclusion: mind the r''!
