This repo contains the Qwen2.5-3B-Instruct-Add-Speech-Token-4096-Nostrip model utilized to train the EMOVA series of models. Based on the original Qwen2.5-3B-Instruct checkpoint, we further insert speech tokens into its vocabulary for end-to-end omni-modal alignment as follows. The total number of speech tokens in EMOVA speech tokenizer is 4096. Therefore, it should be utilized as initialization in the Stage 2: Omni-modal text-centric alignment of EMOVA training.

Usage

To train EMOVA with Qwen2.5-3B-Instruct_add_speech_token_4096_nostrip, we need to create a new model config, and set the language_model parameters as follows. An example is provided here. Check more details on training EMOVA in our github repo.

python

language_model=dict(
  type='EmovaQwen2ForCausalLM',                                              -- Wrapper class type for EMOVA
  pretrained_model_name_or_path='Emova-ollm/Qwen2.5-3B-Instruct_add_speech_token_4096_nostrip',  -- HuggingFace repo of pre-trained LLM
  attn_implementation="flash_attention_2",                                   -- Attention type
  from_pretrained=True,                                                      -- Load pre-trained weights
),
