class_to_idx when inferencing.

[d5423197]

self.class_to_idx is used to save the index corresponding class name. I did not find where this info was saved when training is done. When inferencing, how do we know which class the index corresponds to? Are there any common ways to do this or just save this relation in a separate file?

Thanks,
