Can somebody please help me out with the "Bob The Builder" question. Here's my code:

import numpy as np from sklearn.linear_model import LinearRegression model=LinearRegression() n = int(input()) X = [] for i in range(n): X.append([float(x) for x in input().split()]) y = [int(x) for x in input().split()] datapoint = [float(x) for x in input().split()] y_array=np.asarray(y) datapoint_array=np.asarray(datapoint) datapoint_array.reshape(-1,1) y_array.reshape(-1,1) model.fit(datapoint_array,y_array) print(model.predict(datapoint_array))

model.fit(X,y) print(model.predict(datapoint )[0])

You have to output a single value not list. Otherwise sololearn will not accept. For example "[9]" will be invalid but "9" will be okey. so print only first element using [0]. using numpy is not neccessary here. so you can safely delete datapoint_array and y_array.

fix your last statement like this. do not use int() print(model.predict(datapoint )[0])

you can solve this using Logistic regression model, you will get pass the test case correctly
