Zander Chase	90ef705ced	Update Tool Input (#3103 ) - Remove dynamic model creation in the `args()` property. _Only infer for the decorator (and add an argument to NOT infer if someone wishes to only pass as a string)_ - Update the validation example to make it less likely to be misinterpreted as a "safe" way to run a repl There is one example of "Multi-argument tools" in the custom_tools.ipynb from yesterday, but we could add more. The output parsing for the base MRKL agent hasn't been adapted to handle structured args at this point in time --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	1 year ago

Carmen Sam	d54c88aa21	Add allowed and disallowed special arguments to BaseOpenAI (#3012 ) ## Background This PR fixes this error when there are special tokens when querying the chain: ``` Encountered text corresponding to disallowed special token '<\|endofprompt\|>'. If you want this text to be encoded as a special token, pass it to `allowed_special`, e.g. `allowed_special={'<\|endofprompt\|>', ...}`. If you want this text to be encoded as normal text, disable the check for this token by passing `disallowed_special=(enc.special_tokens_set - {'<\|endofprompt\|>'})`. To disable this check for all special tokens, pass `disallowed_special=()`. ``` Refer to the code snippet below, it breaks in the chain line. ``` chain = ConversationalRetrievalChain.from_llm( ChatOpenAI(openai_api_key=OPENAI_API_KEY), retriever=vectorstore.as_retriever(), qa_prompt=prompt, condense_question_prompt=condense_prompt, ) answer = chain({"question": f"{question}"}) ``` However `ChatOpenAI` class is not accepting `allowed_special` and `disallowed_special` at the moment so they cannot be passed to the `encode()` in `get_num_tokens` method to avoid the errors. ## Change - Add `allowed_special` and `disallowed_special` attributes to `BaseOpenAI` class. - Pass in `allowed_special` and `disallowed_special` as arguments of `encode()` in tiktoken. --------- Co-authored-by: samcarmen <“carmen.samkahman@gmail.com”>	1 year ago

Boris Feld	14e4d30659	Comet ml updates 17 04 2023 (#3074 ) I made a couple of improvements to the Comet tracker: * The Comet project name is configurable in various ways (code, environment variable or file), having a default value in code meant that users couldn't set the project name in an environment variable or in a file. * I added error catching when the `flush_tracker` is called in order to avoid crashing the whole process. Instead we are gonna display a warning or error log message (`extra={"show_traceback": True}` is an internal convention to force the display of the traceback when using our own logger). I decided to add the error catching after seeing the following error in the third example of the notebook: ``` COMET ERROR: Failed to export agent or LLM to Comet Traceback (most recent call last): File "/home/lothiraldan/project/cometml/langchain/langchain/callbacks/comet_ml_callback.py", line 484, in _log_model langchain_asset.save(langchain_asset_path) File "/home/lothiraldan/project/cometml/langchain/langchain/agents/agent.py", line 591, in save raise ValueError( ValueError: Saving not supported for agent executors.

__Jay__	2984ad3964	updated llm response parsing action (#3058 ) Sometimes the LLM response (generated code) tends to miss the ending ticks "```". Therefore causing the text parsing to fail due to not enough values to unpack. The 2 extra `_` don't add value and can cause errors. Suggest to simply update the `_, action, _` to just `action` then with index. Fixes issue #3057	1 year ago

Matthieu	822cdb161b	Adding shared chromaDB client option (#2886 ) This pull request addresses the need to share a single `chromadb.Client` instance across multiple instances of the `Chroma` class. By implementing a shared client, we can maintain consistency and reduce resource usage when multiple instances of the `Chroma` classes are created. This is especially relevant in a web app, where having multiple `Chroma` instances with a `persist_directory` leads to these clients not being synced. This PR implements this option while keeping the rest of the architecture unchanged. Changes: 1. Add a client attribute to the `Chroma` class to store the shared `chromadb.Client` instance. 2. Modify the `from_documents` method to accept an optional client parameter. 3. Update the `from_documents` method to use the shared client if provided or create a new client if not provided. Let me know if anything needs to be modified - thanks again for your work on this incredible repo	1 year ago

Benjamin Scholtz	36138f28c8	Add GoogleSQL prompt (#2992 ) This PR extends upon @jzluo 's PR #2748 which addressed dialect-specific issues with SQL prompts, and adds a prompt that uses backticks for column names when querying BigQuery. See [GoogleSQL quoted identifiers](https://cloud.google.com/bigquery/docs/reference/standard-sql/lexical#quoted_identifiers). Additionally, the SQL agent currently uses a generic prompt. Not sure how best to adopt the same optional dialect-specific prompts as above, but will consider making an issue and PR for that too.
