I have exactly an x86 Ubuntu apt system and do not get this error (and
neither do
my students, Bras at USGS, Charles at RPI, or Shi Jin in UMBC), so
something must
be different. There is something that prevents the import the second
time, but it
probably an error in some installed python package, and I would need
to be on the
system to find it (I already found one in the last version of numpy).
