Errors when drawing Circuits

[hellmersjl3ds]

Whenever I try to show a circuit for example
qc0.png
I get the messages
`FileNotFoundError Traceback (most recent call last)
in ()
3 qc0 = QubitCircuit(N)
4 qc0.add_gate("SWAP", [0, 1], None)
----> 5 qc0.png

61 filename))
---> 62 with open("%s.png" % filename, "rb") as f:
63 result = f.read()
64 else:

FileNotFoundError: [Errno 2] No such file or directory: 'qcirc.png'`

Apparently a file called qcirc.png was supposed to be generated but wasn't.

I installed the "full" version of texlive (sudo apt-get install texlive-full on Ubuntu), and now it is working wonderfully.
