hello. i$\text{'}$m not getting results in my grid. Its blanks.. what am I doing wrong?

$47]$

Knn$\_$nod $=$ KveighborsClassifier$()$

$\text{'}$n$\_$neighbors' : range $(1,4,5)$

knn$\_$grid $=$ GridsearchCv$($knn$\_$mod, knn$\_$params, cv$=5,$ n$\_$jobs$=-1)$

knn$\_$grid.fit $(x,y)$

print$(\text{'}$Best Paraneters: $\text{'},$ knn$\_$grid.best$\_$parans$\_)$

$4.$C $-$ Visualizing Results

Replace the blank in line $1$ of this cell with the name of your parameter dictionary from $4.B.$ Replace the blank in line $2$ with the name of your

GridsearchCV object from $4.$B$.$ Then execute this cell to see how the CV scores varied with respect to the hyperparameter values. Use this

graph to determine if you should re$-$run the previous cell with a different range of hyperparameter values.

n$\_$neighbors $=$ knn$\_$params $["$n$\_$neighbors"$]$

scores $=$ knn$\_$grid.cv$\_$results$\_[\text{'}$mean$\_$test$\_$score'$]$
