What Causes \'AttributeError: \'_multiprocessing.data.DataLoaderIter\' object has no attribute \'next\'\' Error in Python?

Explanation

AttributeError: \'_multiprocessing.data.DataLoaderIter\' object has no attribute \'next\' occurs when you are attempting to use the next() method on a DataLoaderIter object. This error commonly arises when your code is trying to iterate over a DataLoader object using next(), but the object does not support this method.

To resolve this issue, it is essential to review the section of your code where the DataLoaderIter object is instantiated and verify that you are utilizing the appropriate syntax to iterate over the object. Instead of employing next(), consider using a for loop to iterate over the DataLoader object.
