plot.plot_response_curves not working

[TomasPapantos]

Hi,

I'm running the plot.plot_response_curves but I get this error:
"ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()".
Any ideas how to solve it?

Thanks!
Tom

If the log also tells you the function causing the error is _compare_equality_for_lmmm, one of your MMM model attributes is not a proper list of strings (expected) but something else, and you need to fix it.

For example, in my case, when fitting the models, I accidentally passed media_names as a pandas series index
Index(['Facebook', 'Online Video', 'Paid Search'], dtype='object', name='channel')
instead of the correct format
['Facebook', 'Online Video', 'Paid Search']
and it complained.
