Practical overview
When it fits
Use TVLT when a research or prototyping task calls for joint visual-audio representation learning without relying on written text or text tokens, and you can work with a local Python/PyTorch codebase.
Who it is for
- Researchers studying textless multimodal representation learning.
- Developers prototyping models that process video together with its audio channel.
- Practitioners exploring visual-audio features for multimodal understanding or speech-related research.
Documented uses
- Inspect a notebook demo of masked autoencoding on video frames and audio spectrograms.
- Explore video-and-audio sentiment or emotional analysis demos.
- Pretrain or fine-tune the model using the repository’s documented scripts and data guidance.
- Use visual-acoustic representations as a basis for research tasks such as retrieval, audio-based visual question answering, speech translation or multimodal content understanding.
Requirements & limits
The code is available in a public GitHub repository under the MIT license. The documented workflow uses a local Python/PyTorch environment; model weights are listed on Hugging Face.
- The model consumes audio and visual inputs and is designed to avoid text-specific modules, including tokenization and ASR.
- Pretraining uses vision-audio matching and masked autoencoding to reconstruct continuous video-frame and audio-spectrogram inputs.
- The repository provides demos for masked autoencoding, sentiment analysis and emotional analysis.
- The README lists tested PyTorch, torchvision and torchaudio versions and flags CUDA/cuDNN compatibility for other PyTorch versions.
- Pretraining and fine-tuning require following the repository’s separate data and script instructions.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Set up the TVLT Python environment
Prepare the documented Python and dependency environment before using the repository’s demos or training scripts.
Before you start
- The TVLT repository
- Conda
- PyTorch, torchvision and torchaudio compatible with the CUDA and cuDNN setup
- The repository requirements.txt file
Steps
Create a Python 3.8 environment named TVLT with Conda, or choose another Python environment as the README allows.
Install PyTorch, torchvision and torchaudio; the README lists tested version combinations and advises checking compatibility with CUDA and cuDNN.
Install the remaining dependencies with pip install -r requirements.txt.
Expected outcome
A configured Python environment with the repository’s listed dependencies, ready for the separately documented demos or training workflows.
Guide limitations
- This setup guide does not cover running a demo, pretraining or fine-tuning.
- The README’s tested versions are torch 1.10.0 or 1.12.1, torchvision 0.11.1 or 0.12.1, and torchaudio 0.10.0 or 0.13.0.
- Other PyTorch versions require compatibility with the local CUDA and cuDNN setup.
