Apparently, the module "multiarry" is implemented in a separate
DLL (= "Dynamically Loaded Library") and loading this DLL failed.

There can be several reasons for such a failure, among others:

 * the DLL is missing

 * the DLL is corrupted

 * the DLL depends on something which is missing or corrupted

 * there is a version mismatch (e.g. between the DLL and the Python
   trying to load it)


An initial step could be to try to reinstall "numpy" and
see whether the problem goes away.
