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.

This is the error I get when I try to run preprocessing_surf.py. How do I solve this error?

Put the train folder in the same folder with four files mentioned..

@yashsinojiya1898 i have. but it says that the array must be non-empty

[ashok2811]

use '/ ' instead of '\' and '\\' .

@yashsinojiya1898 The folder, did you mean in sklearn ? I am facing the same error right now.

No, put it in the same folder where your code files are.
