Not working on production sixtracktools

[giadarol]

I tried to run the example for the black absorber. I get this error:

$ python black_absorber.py 

Loading line from SixTrack.. 
Traceback (most recent call last):
  File "/Users/giadarol/Desktop/xsuite_packages/xcoll/examples/black_absorber.py", line 18, in <module>
    line = xt.Line.from_sixinput(st.SixInput('./RunIII_B1'))
  File "/Users/giadarol/miniconda3/lib/python3.9/site-packages/xtrack/line.py", line 92, in from_sixinput
    line_data, rest, iconv = _expand_struct(sixinput, convert=class_dict)
  File "/Users/giadarol/miniconda3/lib/python3.9/site-packages/xtrack/loader_sixtrack.py", line 50, in _expand_struct
    if len(sixinput.single[nnn]) == 7:
KeyError: 'GO'

Are you using a special version of sixtracktools?

Fixed by Gianni; anyway production sixtracktools does not exist anymore :-p
