I've upgraded qiskit for the first time in a while and I've discovered that the magic function for displaying backend information doesn't seem to work properly.

Here's what I've tried running:

from qiskit.tools.jupyter import *
backend = P[1].get_backend('ibmq_poughkeepsie')
%qiskit_backend_overview

This returns a ZeroDivisionError.

I've also tried calling backend_monitor(backend), but returns a TypeError, saying that 'module' object is not callable.

I've tried looking into what kind of changes might have been made to the library for monitoring backends, but I cannot seem to find the answer I'm looking for. Any help would be much appreciated!

The %qiskit_backend_overview magic is not deprecated and has seen updates for the most recent 0.11.0 release: https://github.com/Qiskit/qiskit-terra/blob/master/qiskit/tools/jupyter/backend_overview.py to ensure it works with new devices. The ZeroDivisionError might point to a bug in the code for the function or in your calling code, without a full traceback and all code you're running it's hard to know for sure.

I did test it with the latest version qiskit 0.14.1 locally and it still works fine for me:

backend overview

As for backend monitor that also looks fine to me (it doesn't need a magic anymore as the html representation in jupyter for an ibmq backend object is formatted the same way since the qiskit-terra 0.9.0 release):

backend monitor

If the graphical jupyter backends aren't working for you for whatever reason there are always the python functions from qiskit.tools that do the same thing just without any of the graphical output. For example:

backend monitor function
