Usage

Load checkpoint (SpeechBrain format)

import torch
checkpoint = torch.load('checkpoints/CKPT+BEST_WER/model.ckpt')

Load final model (Transformers format)

from transformers import WhisperForConditionalGeneration, WhisperProcessor

model = WhisperForConditionalGeneration.from_pretrained("./final_model")
processor = WhisperProcessor.from_pretrained("./final_model")
