+"""Deprecated module for sentence transformer embeddings.
+
+This module previously provided SentenceTransformerEmbeddings which used the
+sentence-transformers library. The sentence-transformers dependency has been removed
+from LangChain. 
+
+For embedding functionality, please use:
+- HuggingFaceEmbeddings from langchain_huggingface which now uses transformers directly
+- Or install langchain-community which may still contain the legacy implementation
+
+Example migration:
+    # Old way (deprecated):
+    # from langchain.embeddings import SentenceTransformerEmbeddings
+    # embeddings = SentenceTransformerEmbeddings(model_name="all-MiniLM-L6-v2")
+    
+    # New way:
+    from langchain_huggingface import HuggingFaceEmbeddings
+    embeddings = HuggingFaceEmbeddings(model_name="sentence-transformers/all-MiniLM-L6-v2")
