Missing '%matplotlib inline' on several notebooks

[pedrorrivero]

Informations

• Qiskit version: 0.12.1
• Python version: 3.7.4
• Operating system: macOS Mojave v10.14.6

What is the current behavior?

Matplotlib figures do not get plotted unless local ipython configuration files contain the instruction to make matplotlib = "inline". The affected notebooks (inline required but not present) are:

• [ ] ./qiskit/fundamentals/2_plotting_data_in_qiskit.ipynb
• [ ] ./qiskit/advanced/terra/2_operators_overview.ipynb
• [ ] ./qiskit/advanced/terra/3_advanced_circuit_visualization.ipynb
• [x] ./qiskit/advanced/terra/4_transpiler_passes_and_passmanager.ipynb
• [ ] ./qiskit/advanced/aer/1_aer_provider.ipynb
• [x] ./qiskit/advanced/aer/2_device_noise_simulation.ipynb
• [ ] ./qiskit/advanced/aer/3_building_noise_models.ipynb
• [ ] ./qiskit/advanced/aer/4_custom_gate_noise.ipynb
• [ ] ./qiskit/advanced/aer/6_extended_stabilizer_tutorial.ipynb
• [ ] ./qiskit/advanced/ignis/1_calibrating_a_qubit.ipynb
• [ ] ./qiskit/advanced/ignis/4_measurement_error_mitigation.ipynb
• [ ] ./qiskit/advanced/ignis/5a_randomized_benchmarking.ipynb
• [ ] ./qiskit/advanced/ignis/5b_interleaved_rb.ipynb
• [ ] ./qiskit/advanced/ignis/5c_purity_rb.ipynb
• [ ] ./qiskit/advanced/ignis/7_quantum_volume.ipynb
• [ ] ./qiskit/advanced/aqua/artificial_intelligence/qsvm_classification.ipynb
• [ ] ./qiskit/advanced/aqua/finance/simulation/credit_risk_analysis.ipynb
• [ ] ./qiskit/advanced/aqua/optimization/vehicle_routing.ipynb

Steps to reproduce the problem

Reset the ipython configuration files if necessary and run any affected notebook.

What is the expected behavior?

Figures should show up when the notebooks are run.

Suggested solutions

• [ ] Add the %matplotlib inline magic to the beginning of the affected notebooks.
• [ ] Include a brief reference to this behavior in ./qiskit/fundamentals/2_plotting_data_in_qiskit.ipynb.
• [ ] Include a note on how to set the ipython local configuration files (stackoverflow) in ./qiskit/fundamentals/2_plotting_data_in_qiskit.ipynb and/or ./qiskit/advanced/terra/3_advanced_circuit_visualization.ipynb.

It is technically not needed anymore on recent releases of Jupyter.

Great news! Thank you for the update. I am closing this issue then, feel free to reopen if necessary.
