This error occurs when you try to pass a multi-dimensional array or a nested list as input to a function or method that expects a 1-dimensional array. For example, if you have a 2-dimensional array like this: ``` my_array = [[1, 2, 3], [4, 5, 6], [7, 8, 9]] ``` And you try to pass it to a function that expects a 1-dimensional array: ``` my_function(my_array) ``` You will get a ValueError with the message "Input vector should be 1-D." To fix this error, you need to flatten the array or list into a 1-dimensional array before passing it to the function. You can use the numpy.flatten() method to do this for numpy arrays, or the itertools.chain() method for nested lists.
