This seems similar to https://github.com/gentoo-science/sci/issues/473. ipyparallel was split into an own package with ipython 4. I fixed that with https://github.com/gentoo-science/sci/commit/28ed284acb2d6b78c5508cdd43c4a64978af752e, but this change was removed with https://github.com/gentoo-science/sci/commit/375ab383d091bd7fadc9fa063f051bd7d89ef1ae. @jlec, could you please check my latest comment on your commit, which possibly removed my fix?

Didn't explicitly tested to downgrade since productive simulations are running within jupyter on all my machines. Please report if the problem still remains.
