 # How to use
 
+⚠️ You need transformers 4.17+ for the example to work due to its recent support for custom models.
+
 You can use the model straight from the hub but because it contains a custom forward function due to the multilabel attention head you have to pass `trust_remote_code=True`. You can get access to the probabilities for all labels by omitting `return_labels=True`.
