Unable to display latex circuit

[zohimchandani]

Pre-Report Checklist

• [x] I am running the latest versions of pyQuil and the Forest SDK
• [x] I checked to make sure that this bug has not already been reported

Issue Description

Program unable to display circuit with the following error message: ValueError: Unable to render instruction XY(pi) 21 36 which targets non-adjacent qubits.. This is clearly wrong as the 2 qubits are indeed adjacent to each other on the Aspen-9 topology.

Code Snippet

program = qnn_circuit(n_qubits= 8 , n_features = 16, n_parameters = 15)
qc = get_qc('Aspen-9')
native = qc.compiler.quil_to_native_quil(program) 
pyquil.latex.display(native) 

Note that pyquil.latex.display(program) yields the image below but displaying native causes the issue.

Error Output

ValueError: Unable to render instruction XY(pi) 21 36 which targets non-adjacent qubits.
