# YuE2 3B isolated quality test
|
|
|
|
Prepared, non-starting evaluation of `m-a-p/YuE2-3B` with the standard
|
|
`m-a-p/YuE2-Vae` listening decoder. The source is pinned to the official
|
|
`yue2-v0.1.6` commit `9c6c4b349be978b06a9d0d958471a07a6cdeff4d`.
|
|
|
|
Preparation on Athena is complete. The model and VAE files were checked
|
|
against their published `weights_manifest.json` SHA-256 values. The Docker
|
|
image is built, but no YuE2 container has been created or started.
|
|
|
|
## Safety and isolation
|
|
|
|
- This experiment is not part of the profile controller or dashboard.
|
|
- The Compose service uses the `manual` profile, has no restart policy and
|
|
cannot start through an ordinary `docker compose up`.
|
|
- Only the RTX 5080 is exposed to the container.
|
|
- Building and downloading do not load the model or use a GPU.
|
|
- Do not start it while another Athena GPU job is active.
|
|
|
|
## Persistent files
|
|
|
|
```text
|
|
/data/models/yue2/
|
|
├── YuE2-3B/
|
|
└── YuE2-Vae/
|
|
|
|
/data/music/yue2/
|
|
```
|
|
|
|
The initial control request is a true empty-lyrics instrumental request. No
|
|
invented `[Instrumental]` lyrics marker is used.
|
|
|
|
## Community WebUI
|
|
|
|
The `community-ui` profile runs Ladypoly's YuE2 WebUI at the pinned commit
|
|
`8fc05609bde5dcd345d7c6d57fff3da0839164c5`. Only the WebUI layer is copied
|
|
from that repository. Athena continues to use the verified official YuE2
|
|
`0.1.6` runtime and the existing model cache; the WebUI fork's bundled model
|
|
code and Windows installers are not used.
|
|
|
|
The UI is bound only to Athena's localhost on port 8014 and stores complete
|
|
takes below `/data/music/yue2`. Optional Windows-only installers for llama.cpp
|
|
and stable-diffusion.cpp are not part of the Athena setup. Manual composition,
|
|
generation, result playback, score editing and the take library work without
|
|
those optional components.
|
|
|
|
The small integration patch under `community-webui-patches/` fixes the
|
|
community release's missing `refreshArt()` function on Linux and permits the
|
|
native YuE2 empty-lyrics request for true instrumentals. It deliberately does
|
|
not modify the model runtime.
|
|
|
|
```sh
|
|
docker compose --profile community-ui up -d yue2-ui
|
|
```
|
|
|
|
The original small German playground remains available as a stopped fallback
|
|
on localhost port 8016 through the `playground-fallback` profile. Do not run
|
|
both frontends concurrently because both can submit work to the same GPU.
|
|
|
|
## Manual test (only after GPU availability was checked)
|
|
|
|
From `/opt/mike-ai/yue2-3b` on Athena:
|
|
|
|
```sh
|
|
docker compose --profile manual run --rm yue2-test generate \
|
|
--offline \
|
|
--device cuda:0 \
|
|
--budget 16 \
|
|
--request /workspace/requests/instrumental-synthwave.json \
|
|
--output /workspace/runs
|
|
```
|
|
|
|
Start with the official unquantized BF16 path. If and only if this fails from
|
|
VRAM pressure, repeat with `--quantization fp8 --offload-ar`; keep the outputs
|
|
separate because that is a different inference configuration.
|
|
|
|
YuE2 is newly released and officially specifies a 24-GB BF16 GPU. Readiness of
|
|
this image and the downloaded weights is not evidence that the 16-GB RTX 5080
|
|
run will fit or that its audio quality is acceptable.
