Lumina-T2Music

Available as managed deployment Audio Alpha-VLLM Music / audio 1 variants 0 dl/mo

Lumina-T2Music is an open-weight audio or speech model from Alpha-VLLM. AxForge deploys and operates it for you on dedicated EU-owned hardware — with the licence handled where one is required.

Available as managed deployment — configured and operated for you on dedicated EU hardware, quoted per deployment.

About

What Lumina-T2Music is

We will provide our implementation and pretrained models as open source in this repository recently.

📰 News

  • [2024-06-07] 🚀🚀🚀 We release the initial version of Lumina-T2Music for text-to-music generation.

Installation

Before installation, ensure that you have a working nvcc

# The command should work and show the same version number as in our case. (12.1 in our case).
nvcc --version

On some outdated distros (e.g., CentOS 7), you may also want to check that a late enough version of gcc is available

# The command should work and show a version of at least 6.0.
# If not, consult distro-specific tutorials to obtain a newer version or build manually.
gcc --version

Downloading Lumina-T2X repo from github:

git clone https://github.com/Alpha-VLLM/Lumina-T2X

1. Create a conda environment and install PyTorch

Note: You may want to adjust the CUDA version according to your driver version.

conda create -n Lumina_T2X -y
conda activate Lumina_T2X
conda install python=3.11 pytorch==2.1.0 torchvision==0.16.0 torchaudio==2.1.0 pytorch-cuda=12.1 -c pytorch -c nvidia -y

2. Install dependencies

[!Warning] The environment dependencies for Lumina-T2Music are different from those for Lumina-T2I. Please install the appropriate environment.

Installing Lumina-T2Music dependencies:

cd .. # If you are in the `lumina_music` directory, execute this line.
pip install -e ".[music]"

or you can use requirements.txt to install the environment.

cd lumina_music # If you are not in the `lumina_music` folder, run this line.
pip install -r requirements.txt

3. Install flash-attn

pip install flash-attn --no-build-isolation

4. Install nvidia apex (optional)

[!Warning] While Apex can improve efficiency, it is not a must to make Lumina-T2X work.

Note that Lumina-T2X works smoothly with either:

  • Apex not installed at all; OR
  • Apex successfully installed with CUDA and C++ extensions.

However, it will fail when:

  • A Python-only build of Apex is installed.

If the error No module named 'fused_layer_norm_cuda' appears, it typically means you are using a Python-only build of Apex. To resolve this, please run pip uninstall apex, and Lumina-T2X should then function correctly.

You can clone the repo and install following the official guidelines (note that we expect a full build, i.e., with CUDA and C++ extensions)

pip install ninja
git clone https://github.com/NVIDIA/apex
cd apex
# if pip >= 23.1 (ref: https://pip.pypa.io/en/stable/news/#v23-1) which supports multiple `--config-settings` with the same key...
pip install -v --disable-pip-version-check --no-cache-dir --no-build-isolation --config-settings "--build-option=--cpp_ext" --config-settings "--build-option=--cuda_ext" ./
# otherwise
pip install -v --disable-pip-version-check --no-cache-dir --no-build-isolation --global-option="--cpp_ext" --global-option="--cuda_ext" ./

Inference

Preparation

Prepare the pretrained checkpoints.

⭐⭐ (Recommended) you can use huggingface-cli downloading our model:

huggingface-cli download --resume-download Alpha-VLLM/Lumina-T2Music --local-dir /path/to/ckpt

or using git for cloning the model you want to use:

git clone https://huggingface.co/Alpha-VLLM/Lumina-T2Music

Web Demo

To host a local gradio demo for interactive inference, run the following command:

  1. updated AutoencoderKL ckpt path

you should update configs/lumina-text2music.yaml to set AutoencoderKL checkpoint path. Please replace /path/to/ckpt with the path where your checkpoints are located ().

  ...
        depth: 16
        max_len: 1000

    first_stage_config:
      target: models.autoencoder1d.AutoencoderKL
      params:
        embed_dim: 20
        monitor: val/rec_loss
        - ckpt_path: /path/to/ckpt/maa2/maa2.ckpt
        + ckpt_path: /maa2/maa2.ckpt
        ddconfig:
          double_z: true
          in_channels: 80
          out_ch: 80
  ...
  1. setting Lumina-T2Music and Vocoder checkpoint path and run demo

Please replace /path/to/ckpt with the actual downloaded path.

# `/path/to/ckpt` should be a directory containing `music_generation`, `maa2`, and `bigvnat`.

# default
python -u demo_music.py \
    --ckpt "/path/to/ckpt/music_generation" \
    --vocoder_ckpt "/path/to/ckpt/bigvnat" \
    --config_path "configs/lumina-text2music.yaml" \
    --sample_rate 16000

How it works

How audio & music work

Audio or textinputAudio modelrecognise / synthesiseText or audiooutputSpeech-to-text turns audio into text; text-to-speech and music models turn text into audio.

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys lumina-t2music for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (lumina-t2music below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/audio/transcriptions \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -F model="lumina-t2music" -F file=@audio.mp3

Create an account — your API key is available in the console. 5M tokens/month currently included with every new account at launch.
