ValueError: Expected 2D array, got 1D array instead

Using continuous variables. Took a simple input matrix X and target variable y. It seems to run in a problem using sklearn's preprocessing even though the matrix dimensions are correctly set:

ValueError: Expected 2D array, got 1D array instead:
array=[ 1.  1.  1. ...,  0.  0.  0.].
Reshape your data either using array.reshape(-1, 1) if your data has a single feature or array.reshape(1, -1) if it contains a single sample.```
