Hi,

I'm getting the following error when I run the following cell What should I do?

scaler = MinMaxScaler(feature_range=(-1, 1)) train_sc = scaler.fit_transform(train) test_sc = scaler.transform(test)

Expected 2D array, got 1D array instead: array=[17.24 18.190001 19.219999 ... 10.47 10.18 11.04 ]. Reshape your data either using array.reshape(-1, 1)

scaler = MinMaxScaler(feature_range=(-1,1)) train = np.asarray(train).reshape(-1,1) test = np.asarray(test).reshape(-1,1) train_sc = scaler.fit_transform(train) test_sc = scaler.transform(test)
