# Whisper Large V2 zh-HK - Alvin (Weights not uploaded yet)
This model is a fine-tuned version of [openai/whisper-large-v2](https://huggingface.co/openai/whisper-large-v2) on the Common Voice 11.0 dataset. This is trained with PEFT LoRA+BNB INT8.
To use the model, use the following code. It should be able to inference with less than 16GB VRAM.
```
from peft import PeftModel, PeftConfig
from transformers import WhisperForConditionalGeneration, Seq2SeqTrainer, WhisperTokenizer, WhisperProcessor
peft_model_id = "alvanlii/whisper-largev2-cantonese-peft-lora"
peft_config = PeftConfig.from_pretrained(peft_model_id)
model = WhisperForConditionalGeneration.from_pretrained(
peft_config.base_model_name_or_path, load_in_8bit=True, device_map="auto"
)
model = PeftModel.from_pretrained(model, peft_model_id)
task = "transcribe"
tokenizer = WhisperTokenizer.from_pretrained(peft_config.base_model_name_or_path, task=task)
processor = WhisperProcessor.from_pretrained(peft_config.base_model_name_or_path, task=task)
feature_extractor = processor.feature_extractor
forced_decoder_ids = processor.get_decoder_prompt_ids(language=language, task=task)
pipe = AutomaticSpeechRecognitionPipeline(model=model, tokenizer=tokenizer, feature_extractor=feature_extractor)
audio = # load audio here
text = pipe(audio, generate_kwargs={"forced_decoder_ids": forced_decoder_ids}, max_new_tokens=255)["text"]
```
