### Who can help?

_No response_

### Information

- [X] The official example scripts
- [ ] My own modified scripts

### Tasks

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

### Reproduction

from transformers import Wav2Vec2ForCTC, AutoProcessor

ckpt = "./mms-1b-all/"

processor = AutoProcessor.from_pretrained(ckpt)
model = Wav2Vec2ForCTC.from_pretrained(ckpt)  # requires only 3GB of CPU RAM

target_lang = "esp"

processor.set_lang("esp")
model.load_adapter("esp") # This will load a file called "adapter.esp.bin" from: https://huggingface.co/patrickvonplaten/mms-1b-all , cache it and replace the adapter

model.to("cuda")

audio, sr = sf.read("/home/lenovo/下载/audio.flac")
#/home/lenovo/project/fairseq/content/audio_samples/1.wav

inputs = processor(audio, sampling_rate=sr, return_tensors="pt")

with torch.no_grad():
    logits = model(**inputs).logits

transcription = processor.batch_decode(logits.argmax(-1))[0]

print(f"Transcription: {transcription}")

### Expected behavior

Fix this error, and output the correct language, such as 'kor'
