How to modify the Python programming - Support Vector Machine
$begingroup$
Using the SVC algorithm implemented by the Python Scikit-learn, classify the three types of flowers (Setosa, Versicolor, Virgin) in Iris dataset according to the Petal length and width
May I know how to modify my Python programming as refer to the attached file -
