trainer.train()

To be able to use your checkpoint with a pipeline, make sure to save the processor with the checkpoint: 

processor.save_pretrained("YOUR_ACCOUNT_NAME/speecht5_finetuned_voxpopuli_nl")

Push the final model to the 🤗 Hub:

trainer.push_to_hub()

Inference with a pipeline
Great, now that you've fine-tuned a model, you can use it for inference!
First, let's see how you can use it with a corresponding pipeline. Let's create a "text-to-speech" pipeline with your 
checkpoint:
