Dear Uriel,
The printing error that we had is the following:

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    rundcopf()
  File "C:\Python27\lib\site-packages\pypower\opf_model.py", line 143, in
__repr__
    s += '%s  :  <none>\n' , 'NON-LINEAR CONSTRAINTS'
TypeError: cannot concatenate 'str' and 'tuple' objects
