ConfigDict' object has no attribute 'dataset

This error message suggests that the object "ConfigDict" does not have an attribute called "dataset". This could be due to a typo in the code or an incorrect assumption about the properties of the object. It is also possible that the object was not properly initialized or that it was modified in a way that removed the "dataset" attribute.

To resolve this issue, you can check the code and make sure that the object is properly defined and initialized with all the necessary attributes. You can also try printing the object to see if the "dataset" attribute is present or if there are any other issues with the object. If you are still unable to resolve the issue, you may need to seek further assistance or consult the documentation for the object or library you are using.
