This error occurs when the 'Features' feature column is expected to contain a Vector<single> data type (i.e., a vector or array of single-precision floating-point numbers), but instead it contains a Single data type with the argument parameter name as 'Name'. This can happen if there is a mismatch between the data type expected by the model and the data type present in the input data or if there is a formatting issue with the input data, such as missing or extra values. To resolve this error, you need to ensure that the data type in the 'Features' feature column matches the expected data type (i.e., Vector<single>) and that the input data is correctly formatted.
