Confusing error when attempting to start the Jupyter notebook

The following output appeared when I was attempting to start an instance of the Jupyter botebook:

C:\Users\CaitlinG>jupyter notebook
Traceback (most recent call last):
  File "c:\users\caitling\appdata\local\programs\python\python35\lib\runpy.py",
line 184, in _run_module_as_main
    "__main__", mod_spec)
  File "c:\users\caitling\appdata\local\programs\python\python35\lib\runpy.py",

    exec(code, run_globals)

    from zmq.eventloop import ioloop
  File "c:\users\caitling\appdata\local\programs\python\python35\lib\site-packag

    _libzmq = ctypes.cdll.LoadLibrary(bundled[0])

it__.py", line 425, in LoadLibrary
    return self._dlltype(name)
  File "c:\users\caitling\appdata\local\programs\python\python35\lib\ctypes\__in
it__.py", line 347, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: [WinError 126] The specified module could not be found

I am using Windows 10 and Python 3.5.2. I installed the package, along with its dependencies, via: pip3 install "ipython[notebook]" --upgrade

The aforementioned process proceeded without incident but I am confused why the issue has appeared.

Thanks.

It seems to be an issue with pyzmq 15.3. Installing a previous version worked for me:

pip install pyzmq==15.2

See: https://github.com/jupyter/help/issues/62

Good luck!
