The "del sys" line was introduced in the commit:

https://github.com/numpy/numpy/commit/4c0576fe9947ef2af8351405e0990cebd83ccbb6

and it seems to me that it is needed so that the numpy.core namespace is not
cluttered by it.

Can you post the full stacktrace of your program (and preferably some
instructions
how to reproduce the problem)? It should become clear where the problem is.

Thanks,
Ondrej
