What can't run here
sentence-transformers and PyTorch don't run in the browser Python runtime. For neural embeddings use the in-browser model in the Embeddings lab, the backend's /api/embeddings endpoint (when installed with the ML extras), or run locally: pip install sentence-transformers then SentenceTransformer("all-MiniLM-L6-v2").encode(texts).
