If you have tornado 5, you need pyzmq 17. Older versions of pyzmq are not compatible with tornado 5.

right now, my python3-zmq version give 16.0.2-2+b1.
i've to wait for the 17 one (repo version) to play with jupyter-notebook on debian!
thx

Or install pyzmq using pip or conda. If Debian has packaged tornado 5 but not pyzmq 17, then complain to Debian about it - we don't control Debian packages.

[Cherkah]

ok thanks for the idea about pip....
issue resolve :)

Great :-)
