info_plots.actual_plot() got an error

[mfgray]

I ran in to this issue too. The info_plots.actual_plot() has the keyword argument predict_kwds which has the default value None, which seems to be causing the error with the argument unpacking (**). I was getting the same error.
"""
predict() argument after ** must be a mapping, not NoneType
"""

I was able to get it to work by passing in an empty set as the keyword argument. I.e. when calling actual_plot pass in the following keyword arg:
predict_kwds={}

Looking at the git commits it looks like the author had recently changed the default from an empty set to None.

Hi,

the error message points to the following line in the source code
prediction = predict(X, **predict_kwds)
I just changed this line to prediction = predict(X) and then it worked again. Probably the scikit API changed in recent updated and it's not possible anymore to overload an additional None value.
