--------------------------------------------------- MY CODE IS: query_x = np.array([150,80]) plt.scatter(X[:,0],X[:,1],c=Y) plt.scatter(query_x[0],query_x[1],color=‘red’) plt.show() def dist(x1,x2): return np.sqrt(sum((x1-x2)**2)) def knn(X,Y,queryPoint,k=5): vals=[] m=X.shape[0] for i in range(m): d = dist(queryPoint,X[i]) vals.append((d,Y[i])) vals = sorted(vals) #NeAREST FIRST K POINTS vals = vals[:k] vals = np.array(vals) print(vals) knn(X,Y,query_x)//Calling the Function here.

I can't figure out the error please check
Hey @YashSINGHAI, print shape/length of x1 and x2 you are passing to the dist function. It seems that in line d = dist(queryPoint,X[i]) , X[i] has 7 values and query point has only 2 values. Shapes of both these vectors must be same. So use queryPoint having 7 values and not 2.
Hope this resolved your doubt.
