python-argon2-cffi, python-ipykernel, python-ipython-genutils, python-jinja2,
python-jupyter-client, python-pyzmq, python-tornado-6, and python-traitlets.
[native-inputs]: Remove python-nose and python-sphinx; add python-coverage,
python-nbval, python-pytest, python-pytest-cov, and
python-requests-unixsocket.
[arguments]: Use pytest instead of nosetests.
