Who can help?

@Narsil There's a typo in ImageClassificationPipeline, that I don't believe usually has any effect, but it's confusing when reading the code. I will provide a PR with a fix.

Information

• The official example scripts
• My own modified scripts

Tasks

• An officially supported task in the examples folder (such as GLUE/SQuAD, ...)
• My own task or dataset (give details below)

Reproduction

This typo does not cause behavior change, because of the or self.model.config.num_labels == 1/> 1 condition.

Expected behavior

The problem_type condition should match the num_labels condition
