IndexError: list index out of range

[moezali1]

Hi. We have recently integrated AutoViz into PyCaret and I think I found an edge case here that needs to be fixed in AutoViz. This problem only happens when the dataset only has 1 numeric feature. My guess is that it needs at least 2 variables for the scatter plot. The expected fix will basically involve some kind of exception handling.

To reproduce the error:

pip install pycaret

from pycaret.datasets import get_data
data = get_data('cancer')

from pycaret.classification import *
s = setup(data, target = 'Class', session_id = 123, silent = True)

eda()
