Final answer:
This error occurs when trying to use the next() method on a SingleProcessDataLoaderIter object.
This error occurs when trying to use the next() method on an object of type SingleProcessDataLoaderIter. The SingleProcessDataLoaderIter class does not have a next() method, which is why this error is thrown.
To resolve this error, you need to check the documentation or source code of the SingleProcessDataLoaderIter class to see if there is an alternative method or approach to iterate through the data. Alternatively, you can try using a different object or class that does have a next() method.
It's important to note that the specific solution may depend on the programming language and framework being used. Be sure to consult relevant documentation or seek assistance from the appropriate programming community or support channels.
