SQLDatabase chain having issue running queries on the database after connecting
Langchain SQLDatabase and using SQL chain is giving me issues in the recent versions. My goal has been this: - Connect to a sql server (say, Azure SQL server) using mssql+pyodbc driver (also tried mssql+pymssql driver) `connection_url = URL.create( "mssql+pyodbc", query={"odbc_connect": conn} )` `sql_database = SQLDatabase.from_uri(connection_url)` - Use this sql_database to create a SQLSequentialChain (also tried SQLChain) `chain = SQLDatabaseSequentialChain.from_llm( llm=self.llm, database=sql_database, verbose=False, query_prompt=chain_prompt)` - Query this chain However, in the most recent version of langchain 0.0.88, I get this issue: <img width="663" alt="image" src="https://user-images.githubusercontent.com/25394373/219547335-4108f02e-4721-425a-a7a3-199a70cd97f1.png"> And in the previous version 0.0.86, I was getting this: <img width="646" alt="image" src="https://user-images.githubusercontent.com/25394373/219547750-f46f1ecb-2151-4700-8dae-e2c356f79aea.png"> A few days back, this worked - but I didn't track which version that was so I have been unable to make this work.

SQLite Cache memory for async agent runs fails in concurrent calls
I have a slack bot using slack bolt for python to handle various request for certain topics. Using the SQLite Cache as described in here https://langchain.readthedocs.io/en/latest/modules/llms/examples/llm_caching.html Fails when asking the same question mutiple times for the first time with error > (sqlite3.IntegrityError) UNIQUE constraint failed: full_llm_cache.prompt, full_llm_cache.llm, full_llm_cache.idx As an example code: ```python3 from langchain.cache import SQLiteCache langchain.llm_cache = SQLiteCache(database_path=".langchain.db") import asyncio from slack_bolt.async_app import AsyncApp from slack_bolt.adapter.socket_mode.async_handler import AsyncSocketModeHandler # For simplicity lets imagine that here we # instanciate LLM , CHAINS and AGENT app = AsyncApp(token=SLACK_BOT_API_KEY) async def async_run(self, agent_class, llm, chains): @app.event('app_mention') async def handle_mention(event, say, ack): # Acknowlegde message to slack await ack() # Get response from agent response = await agent.arun(message) #Send response to slack await say(response) handler = AsyncSocketModeHandler(app, SLACK_BOT_TOKEN) await handler.start_async() asyncio.run(async_run(agent, llm, chains)) ``` I imagine that this has something to do with how the async calls interact with the cache, as it seems that the first async call creates the prompt in the sqlite mem cache but without the answer, the second one (and other) async calls tries to create the same record in the sqlite db, but fails because of the first entry.

LLM making its own observation when a tool should be used
I'm playing with the [CSV agent example](https://langchain.readthedocs.io/en/latest/modules/agents/agent_toolkits/csv.html) and notice something strange.

LLM making its own observation when a tool should be used

UT test_bash.py broken on MacOS dev environment
I forked & cloned the project to my dev env on MacOS, then ran 'make test', the test case 'test_incorrect_command_return_err_output' from test_bash.py failed with the following output: <img width="1139" alt="image" src="https://user-images.githubusercontent.com/64731944/221828313-4c3f6284-9fd4-4bb5-b489-8d7e911ada03.png"> I then tried the test in my Linux dev env, the test case passed successfully. this line of code in the test case: `output = session.run(["invalid_command"])` its output on MacOS is: `/bin/sh: invalid_command: command not found\n` and on Linux it is `/bin/sh: 1: invalid_command: not found\n` The difference is from the underlying "subprocess" library, and as lots of developers use MacOS as their dev env, I think it makes sense to make the test case support both MacOS and Linux, so I would suggest using a regex to do the assertion: `assert re.match(r'^/bin/sh:.*invalid_command.*not found.*$', output)`

Document loader for Azure Blob storage
Lots of customers is asking if langchain have a document loader like AWS S3 or GCS for Azure Blob Storage as well.

How metadata is being used during similarity search and query?

Here what I have: ``` pinecone.init( api_key=PINECONE_API_KEY, environment=PINECONE_API_ENV ) index_name = "index" embeddings = OpenAIEmbeddings(openai_api_key=OPENAI_API_KEY) docsearch = Pinecone.from_existing_index(index_name=index_name, embedding=embeddings) llm = ChatOpenAI(temperature=0, openai_api_key=OPENAI_API_KEY) chain = load_qa_chain(llm, chain_type="stuff") query = "What is the total revenue of Apple?" docs = docsearch.similarity_search(query, include_metadata=True) res = chain.run(input_documents=docs, question=query) print(res) ``` However, there are still document chunks from non-Apple documents in the output of `docs`. What am I doing wrong here and how do I utilize the information in metadata both on doc_search and chat-gpt query (If possible)? Thanks
