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.
