How to Get Started with the Model

Pytorch

import torch
from transformers import HubertModel

model = HubertModel.from_pretrained("team-lucid/hubert-xlarge-korean")

wav = torch.ones(1, 16000)
outputs = model(wav)
print(f"Input:   {wav.shape}")  # [1, 16000]
print(f"Output:  {outputs.last_hidden_state.shape}")  # [1, 49, 768]

JAX/Flax

import jax.numpy as jnp
from transformers import FlaxAutoModel

model = FlaxAutoModel.from_pretrained("team-lucid/hubert-xlarge-korean", trust_remote_code=True)

wav = jnp.ones((1, 16000))
outputs = model(wav)
print(f"Input:   {wav.shape}")  # [1, 16000]
print(f"Output:  {outputs.last_hidden_state.shape}")  # [1, 49, 768]

Inference Examples
This model does not have enough activity to be deployed to Inference API (serverless) yet. Increase its social visibility and check back later, or deploy to Inference Endpoints (dedicated) instead.
