How many training iterations are conducting in the following tuning experiment? from sklearn import svm$,$ datasets

from sklearn.model$\_$selection import GridsearchCV

iris $=$datasets.load$\_$iris$()$

parameters $=\{\text{'}$kernel$\text{'}$: $(\text{'}$linear$\text{'},$ 'poly', $\text{'}$rbf$\text{'}),\text{'}$C$\text{'}$:$[1,5,10]\}$

SVC $=$ Svm$.$SVC$()$ clf $=$ GridSearchCV$($svc$,$ parameters, cv$=3)$

clf$.$fit$($iris$.$data, iris.target$)$
