Changelog

• Added necessary task encoders for energon data module to support training LLaVA NeXT with NeVA Model

Usage

The only change is to use the energon based data module as shown below with existing NeVA model

from nemo.collections.multimodal.data.energon.config import MultiModalSampleConfig
from nemo.collections.vlm import LlavaNextTaskEncoder
from nemo.collections.multimodal.data.energon import SimpleMultiModalDataModule
from transformers import AutoProcessor
processor = AutoProcessor.from_pretrained("llava-hf/llava-v1.6-mistral-7b-hf")
    data_path = args.data_path
    image_processor = processor.image_processor
    tokenizer = processor.tokenizer

    multimodal_sample_config = MultiModalSampleConfig()

    task_encoder = LlavaNextTaskEncoder(
        tokenizer=tokenizer, image_processor=image_processor, multimodal_sample_config=multimodal_sample_config
    )
    data = SimpleMultiModalDataModule(
        path=data_path,
        tokenizer=tokenizer,
        image_processor=image_processor,
        num_workers=8,
        micro_batch_size=mbs,
        global_batch_size=gbs,
        multimodal_sample_config=multimodal_sample_config,
        task_encoder=task_encoder,
    )

GitHub Actions CI

The Jenkins CI system has been replaced by GitHub Actions self-hosted runners.

The GitHub Actions CI will run automatically when the "Run CICD" label is added to the PR.
To re-run CI remove and add the label again.
