Duplicated circuit visualizations on Quantum Lab

[filippotramonto]

Informations

• Qiskit version: qiskit version present on Quantum Lab
• Python version: Python version on Quantum Llab
• Operating system: OS on Quantum Lab

What is the current behavior?

In all tutorials where the command %matplotlib inline in executed, when then the command .draw('mpl') is executed for visualize the circuit the circuit is drawn 2 times.

Steps to reproduce the problem

• run a cell containing %matplotlib inline
• run a cell containing .draw('mpl')

What is the expected behavior?

The circuit should be drawn only one time

Suggested solutions

Remove the line with %matplotlib inline

I dont have %matplotlib inline explicitly defined in my notebook but circuit.draw('mpl') produces 2 outputs. Any ideas whats happening there?

Hey you can look in Qiskit/qiskit-terra#6889. Hope this helps 🙂
