I don't think nimpy works with numpy yet. You'd have to implement these functions: [https://docs.scipy.org/doc/numpy-1.15.0/reference/c-api.array.html](https://docs.scipy.org/doc/numpy-1.15.0/reference/c-api.array.html)
But how it should work if `a` was a regular python array would be:
for i in a.to(seq[int]):
echo("i = ", $i)
Run
