Why the last stable version doesn't work? It seems the circuit is not parsed, how do I parse it?
It also happens with PySpice 1.4, although the same line is uncommented.
Environment (OS, Python version, PySpice version, simulator)
Ubuntu 20.04.5 LTS, Python 3.10, PySpice 1.5
Actual Behaviour
The last commented line from https://pyspice.fabrice-salvaire.fr/releases/v1.5/examples/advanced-usages/internal-device-parameters.html (compute the DC transfer function) failed
