TypeError: data type 'Float64' not understood

This error message typically occurs when a function or operation is expecting a different data type than the one that is provided. In this case, the function or operation is expecting a data type it does not understand or recognize, which is Float64.

To resolve this error, you should check the data type of the variable or value that is causing the error and ensure that it is compatible with the function or operation. If necessary, you may need to convert the data type to a format that the function or operation understands.
