I am getting the following error. Basically, the kernel does not start and throws the following error.
jupyter notebook

Tried to debug using,
brew info zmq
zeromq: stable 4.3.1 (bottled), HEAD
@mogarg Did you find a solution to this issue? I'm seeing the same thing and hope to avoid duplicating effort.
For future users: it looks like in my case, brew upgraded my zeromq libraries from v4.2.4 to v4.3.1, and so I needed to update and rebuild (or remove and completely reinstall) gophernotes so that it was linked against the same version at runtime that is was originally built against.
In my case, zmq4.3.3 was installed and got the error "zmq4 was installed with ZeroMQ version 4.3.2, but the application links with version 4.3.3"
How to install zeromq 4.3.2:
Search commit hash of 4.3.2 in the log then checkout.
cd /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/
git checkout 915a80b94801fc6339bbd8fb802e7ee347913145 zeromq.rb
brew unlink zeromq
brew install zeromq
git reset --hard
brew link zeromq
Nowadays gophernotes is using a pure-Go zmq4 library so that kind of error is most probably coming from an installation problem of jupyter itself rather than gophernotes.
Closing as 'not a gophernotes issue anymore'.
(Feel free to reopen if you think that's not the case)
