bug/Deprecation Warning in LangChain: OpenAIEmbeddings Deprecated

[ron-unstructured]

Describe the bug When using the OpenAIEmbeddingEncoder from the unstructured package, a deprecation warning is issued:

LangChainDeprecationWarning: The class `langchain_community.embeddings.openai.OpenAIEmbeddings` was deprecated in langchain-community 0.0.9 and will be removed in 0.2.0. An updated version of the class exists in the langchain-openai package and should be used instead. To use it run `pip install -U langchain-openai` and import as `from langchain_openai import OpenAIEmbeddings`.
  warn_deprecated(

To Reproduce

1. run this code:

   
   import os

from unstructured.documents.elements import Text from unstructured.embed.openai import OpenAIEmbeddingConfig, OpenAIEmbeddingEncoder

Initialize the encoder with OpenAI credentials

embedding_encoder = OpenAIEmbeddingEncoder(config=OpenAIEmbeddingConfig(api_key=os.environ["OPENAI_API_KEY"]))

Embed a list of Elements

elements = embedding_encoder.embed_documents( elements=[Text("This is sentence 1"), Text("This is sentence 2")], )

Embed a single query string

query = "This is the query" query_embedding = embedding_encoder.embed_query(query=query)

Print embeddings

[print(e.embeddings, e) for e in elements] print(query_embedding, query) print(embedding_encoder.is_unit_vector(), embedding_encoder.num_of_dimensions())

2. output:
LangChainDeprecationWarning: The class `langchain_community.embeddings.openai.OpenAIEmbeddings` was deprecated in langchain-community 0.0.9 and will be removed in 0.2.0. An updated version of the class exists in the langchain-openai package and should be used instead. To use it run `pip install -U langchain-openai` and import as `from langchain_openai import OpenAIEmbeddings`.

**Expected behavior**
No deprecation warning should be displayed. The code should use the updated `OpenAIEmbeddings` class from the `langchain-openai` package as suggested.

**Environment Info**
- Unstructured: 0.14.11.dev3
- langchain-community: 0.0.29
- langchain-openai: 0.0.5
