An updated version of the class exists in the :class:~langchain-huggingface package and should be used instead. To use it run pip install -U :class:~langchain-huggingface and import as from :class:~langchain_huggingface import HuggingFaceEmbeddings``.
embeddings = SentenceTransformerEmbeddings(model_name="all-MiniLM-L6-v2")

I've encountered deprecation warnings in LangChain despite trying the recommended fixes.

Specifically, the warnings are about DirectoryLoader, SentenceTransformerEmbeddings, and Pinecone being deprecated.

I've updated the imports as suggested, attempted using the LangChain CLI for automatic updates, and verified library versions, but the issue persists.

I'm running this on Windows with Python (specific version), and the LangChain library is updated to the latest version.

If anyone has faced this issue or knows how to resolve it, your guidance would be appreciated!

Currently throwing this error on MacOS:

CLIError: Failed to download Grit CLI from
https://github.com/getgrit/gritql/releases/latest/download/marzano-aarch64-apple-darwin.tar.gz

That file doesn't exist.

@ccasgar

is that you mean you get to see error with langchain library

[ccasgar]

The error is visible in a terminal window when invoking the langchain-cli from a command line

The issue is with the lanchain library as it is deprecated but not upgraded those with new migrated libraries to work with .
