I'm Runnning Sage 7.2 on OS Sierra. All was running fine until I tried to run the line: VS = VectorSpace(GF(2), 5)

I get the error:

ImportError: dlopen(/Users/name/Library/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/numpy/core/multiarray.so, 2): Symbol not found: _PyUnicodeUCS2_AsASCIIString
  Referenced from: /Users/name/Library/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/numpy/core/multiarray.so
  Expected in: flat namespace
 in /Users/name/Library/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/numpy/core/multiarray.so

If anyone could shed some light on this I'd be very grateful. Could it be that Sagemath 7.2 has incompatibilities with OS Sierra?

Many Thanks Patrick

Hi all, a fairly general question. I've installed sage both on a virtual machine and from source. I would expct that the source build would be more powerful as a virtual machine can only use some but not all of the system's power. When implementing a primality testing algorith (3000 digit primes), the virtual machine is significantly faster and is so on other large computations. Can anyone give a reason for this? I'm running it on El capitan (mac), core i5 intel processor with 12GB RAM. Additionally, the amount of RAM being consumed is nowhere near the full amount available.

If anyone could shed some light on this or suggest a way to speed up my sagemath software (excluding the cloud) i'd be very grateful.
