Hi,
While compiling this program from tutorial problem is struck
-----------------------------------------------
output = mesolve(H, psi0, tlist, c_op_list, [a.dag() * a, sm.dag() * sm])
>>>
>>> fig, ax = plt.subplots(figsize=(8,5))
>>> ax.plot(tlist, output.expect[0], label="Cavity")
[<matplotlib.lines.Line2D object at 0x7fc5cc461630>]
>>> ax.plot(tlist, output.expect[1], label="Atom excited state")
[<matplotlib.lines.Line2D object at 0x7fc5cc461f60>]
>>> ax.legend()
<matplotlib.legend.Legend object at 0x7fc5cc473128>
>>> ax.set_xlabel('Time')
<matplotlib.text.Text object at 0x7fc5cc48a748>
>>> ax.set_ylabel('Occupation probability')
<matplotlib.text.Text object at 0x7fc5cc49edd8>
>>> ax.set_title('Vacuum Rabi oscillations');
<matplotlib.text.Text object at 0x7fc5cc4ba588>
---------------------------------------------------------------------------
What should I do now
