Finetuning ASR models and change the vocabulary error！！！
That's more of a warning than an error. The actual crash is because of the OSErrorv- network is unreachable. HF wpe requires connecting to the HF servers even for local models, you need to use the environment flag TRANSFORMERS_OFFLINE=1 (or set that in os.environ before importing HF). 

Otherwise you can create and use a sentence piece tokenizer instead (recommended)  This issue is stale because it has been open for 30 days with no activity. Remove stale label or comment or this will be closed in 7 days. This issue was closed because it has been inactive for 7 days since being marked as stale.
My code:
....
model = nemo_asr.models.ASRModel.from_pretrained("stt_en_citrinet_512")
model.change_vocabulary(
    new_tokenizer_dir="./tokenizers/an4/tokenizer_spe_unigram_v32/",
    new_tokenizer_type="wpe"
)

**error:
You tried to register an artifact under config key=tokenizer.vocab_path but an artifact for it has already been registered**.
