Hello. The error occurs when I insert into the file a script of type Folded->Executable->Python to generate the picture.

Here is the code:

```tm
<\script-input|python|default>
  import schemdraw

  import schemdraw.elements as elm
 
  \;

  d = schemdraw.Drawing()

  d += elm.Resistor().label('100K\<Omega\>')

  d += elm.Capacitor().down().label('0.1\<mu\>F', loc='bottom')

  d += elm.Line().left()

  d += elm.Ground()

  d += elm.SourceV().up().label('10V')

  \;

  bit = d.draw(show=False).getimage('eps')

  ps_out(bit.decode())
</script-input|>

```

I successfully fixed it by edit `postscript.py` and `protocol.py` in `plugins/tmpy`. I attached the .diff files in this report.

In `plugins/tmpy/postscript.py`, line 83, code should not enter the `for loop` when the out.find('\n') > 0 is True.
In `plugins/tmpy/protocol.py`, line 37, because the change abosve, data maybe a str type value, so add code to encode it before reture.

By the way, bytes can be added as a supported data type. It is useful in many third-party Python packages.
