nose doesn't affect importing; the test file imports work as normal.
If you want to test code in-place, you will need to do a build_ext
--inplace and set your sys.path accordingly (via PYTHONPATH, .pth
files, whatever). If you use setuptools/easy_install, this is all
combined: "python setupegg.py develop". In order to use an in-place
numpy to build packages like scipy, you will also need to symlink or
copy the generated header files into the appropriate places:

  python setup.py build_ext --inplace
  cd numpy/core/include/numpy
  ln -s ../../*.h .
