Forgive me if this is a basic question. I have a matrix stored in an IDL
save file. I have been trying to read it in using PyCall and
scipy.io.readsav
julia> using PyCall
julia> @pyimport scipy.io as io
julia> a=io.readsav("weight_and_dist.sav")
/usr/lib/python2.7/dist-packages/scipy/io/idl.py:167: UserWarning: warning:

Could someone direct me towards the correct way to convert PyObjects to
Arrays.
