ValueError: Input must be >= 2-d.

This error occurs when a function or method expects an input that is at least two-dimensional, but the input provided is either one-dimensional or is not numeric.

For example, if you try to use a machine learning algorithm that requires a dataset with multiple features, and you provide a single column of data, you will get this error. Similarly, if you try to perform a matrix operation on a scalar value, you will also get this error.

To fix this error, you need to make sure that the input you are providing meets the expected dimensions and data type. This may involve reshaping your data, adding additional features or dimensions, or converting non-numeric data to numeric data.

raise ValueError("Input must be >= 2-d.") ValueError: Input must be >= 2-d.

This error message indicates that the input provided to a function or method should be a matrix or an array with at least two dimensions. In other words, the input should have multiple rows and columns, rather than being a one-dimensional list or array.

To fix this error, you can modify the input so that it has at least two dimensions. For example, if you have a list of numbers, you can convert it to a 2D array using numpy:

import numpy as np

my_list = [1, 2, 3, 4, 5]
my_array = np.array(my_list).reshape(-1, 1)

This will create a 2D array with one column and five rows. If you need a different shape, you can adjust the reshape arguments accordingly. Once you have a 2D array, you can pass it to the function or method without encountering the ValueError.
