Generate Spatial Weights Matrix error in ArcGIS 10.2

Question

I have been unable to run the Generate Spatial Weights Matrix in ArcGIS 10.2.
I always get the same error:

Failed to execute (GenerateSpatialWeightsMatrix).

I am not sure if this is an error from ArcGIS or a configuration error with Python.

Thanks in advance for any help.

Note that this issue is now solved at ArcGIS 10.3 or later, and in ArcGIS Pro.

Thank you, Francisco

Your work also give me some guides on solving matrix generation error.

I'm really appreciate you.

Best regards.

Shaun,
You are right!
Since I am using Canopy 1.3.0 (which uses Python 2.7.6 with Numpy 1.8.0 and matplotlib 1.3.1 instead of Numpy 1.6.1 and matplotlib 1.1.1 which is used by the Python 2.7.3 that comes with ArcGIS 10.2) I thought it was an incompatibility problem somewhere.

But you may see the "á" in my path, and removing this has solved the problem.

Many thanks,
