[IPython-user] ipythonrc-scipy and numpy

I am trying to edit my ipythonrc-scipy profile to eliminate some error
messages related to Numeric.  I don't have Numeric installed and I
think these errors are slowing down my boot up time.

Is the line
execfile Extensions/numeric_formats.py
necessary at all if I am using only the new numpy (i.e. I have neither
Numeric nor numarray installed)?  From a quick glance at
numeric_formats.py it looks like it is used to print Numeric arrays to
the screen.  Running IPython -pylab -p scipy with this line commented
out doesn't seem to cause problems for printing numpy arrays:

In [1]: t=arange(0,10,0.001)

In [2]: t
Out[2]:
array([  0.00000000e+00,   1.00000000e-03,   2.00000000e-03, ...,
         9.99700000e+00,   9.99800000e+00,   9.99900000e+00])

I also changed this line
import_all scipy IPython.numutils

to just
import_all scipy

I haven't seen any adverse affects so far, but don't completely
understand the ramifications.

Thanks,

Ryan
