| # Seamless Streaming demo | |
| ## Running on HF spaces | |
| You can simply duplicate the space to run it. | |
| ## Running locally | |
| ### Install backend seamless_server dependencies | |
| > [!NOTE] | |
| > Please note: we *do not* recommend running the model on CPU. CPU inference will be slow and introduce noticable delays in the simultaneous translation. | |
| > [!NOTE] | |
| > The example below is for PyTorch stable (2.1.1) and variant cu118. | |
| > Check [here](https://pytorch.org/get-started/locally/) to find the torch/torchaudio command for your variant. | |
| > Check [here](https://github.com/facebookresearch/fairseq2#variants) to find the fairseq2 command for your variant. | |
| If running for the first time, create conda environment and install the desired torch version. Then install the rest of the requirements: | |
| ``` | |
| cd seamless_server | |
| conda create --yes --name smlss_server python=3.8 libsndfile==1.0.31 | |
| conda activate smlss_server | |
| conda install --yes pytorch torchvision torchaudio pytorch-cuda=11.8 -c pytorch -c nvidia | |
| pip install fairseq2 --pre --extra-index-url https://fair.pkg.atmeta.com/fairseq2/whl/nightly/pt2.1.1/cu118 | |
| pip install -r requirements.txt | |
| ``` | |
| ### Install frontend streaming-react-app dependencies | |
| ``` | |
| conda install -c conda-forge nodejs | |
| cd streaming-react-app | |
| npm install --global yarn | |
| yarn | |
| yarn build # this will create the dist/ folder | |
| ``` | |
| ### Running the server | |
| The server can be run locally with uvicorn below. | |
| Run the server in dev mode: | |
| ``` | |
| cd seamless_server | |
| uvicorn app_pubsub:app --reload --host localhost | |
| ``` | |
| Run the server in prod mode: | |
| ``` | |
| cd seamless_server | |
| uvicorn app_pubsub:app --host 0.0.0.0 | |
| ``` | |
| To enable additional logging from uvicorn pass `--log-level debug` or `--log-level trace`. | |
| ### Debuging | |
| If you enable "Server Debug Flag" when starting streaming from the client, this enables extensive debug logging and it saves audio files in /debug folder. |
