Hi I have a problem with installation of numpy ! I followed the instructions from the page of scipy and tried
sudo apt-get install python-numpy python-scipy too.
It shows this message:

blago@blago-laptop:~$ python

    import defchararray as char

    from numpy.core.multiarray import _vec_string
ImportError: cannot import name _vec_string

Can you help me???

From the Python documentation:

exception ImportError
Raised when an import statement fails to find the module definition or when a from ... import fails to find a name that is to be imported.

In numpy/core/multiarray.py, is there a symbol named _vec_string?

Is it a version of numpy under development?
If you use a previous version of numpy, is the import error still there?
Have you contacted authors of numpy about this problem?
