Could not load embeddings from string '{embed}'. {version_in
Error message
Could not load embeddings from string '{embed}'. {version_info} loading embeddings by provider:identifier string requires langchain>=0.3.9 as well as the provider-specific package. Install LangChain with: pip install 'langchain>=0.3.9' and the provider-specific package (e.g., 'langchain-openai>=0.3.0'). Alternatively, specify 'embed' as a compatible Embeddings object or python function. What it means
