Eppy for EnergyPlus 'The objective is not pickable'

edit

I would like to use Eppy to change some attributes in IDF files. And when I tried I got some errors.

My code simply follows the tutorial from Eppy tutorial web page.

schedules=idf1.idfobjects['SCHEDULE:COMPACT']
occschedules=schedules[22]
print occschedules

The error I am getting here is:

raise RepresenterError("cannot represent an object: %s" % data)
yaml.representer.RepresenterError: cannot represent an object: <eppy.bunch_subclass.CheckRange object at 0x0D13B850>

And the schedule in IDF file I would like to print is showing below:

Schedule:Compact,
