If you are building numpy inplace, you will also have to delete the
inplace headers.
nuke:
rm -rf build
rm -f numpy/core/include/numpy/__multiarray_api.c
numpy/core/include/numpy/__multiarray_api.h
numpy/core/include/numpy/__ufunc_api.c
numpy/core/include/numpy/__ufunc_api.h numpy/core/include/numpy
/__umath_generated.c
rm -f `find . -name "*.so"`
