Question

I am using Python 2.6, Excel 2007 Professional and the latest version of PyXLL. When loading a module in PyXLL that has

import scipy

An exception is thrown and the module is not loaded. Has anyone been able to load Scipy in PyXLL? Could it be a versioning problem? The exception thrown is:

Solution

I suspect this is because you are using the Enthought distribution of NumPy. The current version available has a problem that means it cannot be embedded in Excel.

To fix this, you need to remove the manifest resources from the numpy pyd files using cff explorer or any other PE editor.

Enthought are aware of this and are looking at the problem.

The version you can download from the numpy website works fine with PyXLL.

If you have any other issues, feel free to email support@pyxll.com or post on the PyXLL forum.
