| ### Issue you'd like to raise.
I am currently working on the task of **article rewriting**, and both the QA chain and Summarize chain are not quite suitable for my task.
Since I need to rewrite **multiple "lengthy"** articles, I would like to know how to use the chain_type in LLMchain. Alternatively, are there any other methods to achieve segment-level rewriting? Thank you.

| ### Feature request
Add embedding support to the callback system. Here is one approach I have in mind.
- [ ] Add `on_embedding_start` method on `CallbackManagerMixin` in `libs/langchain/langchain/callbacks/base.py`.
- [ ] Implement `EmbeddingManagerMixin` with `on_embedding_end` and `on_embedding_error` methods in `libs/langchain/langchain/callbacks/base.py`.
- [ ] Add embedding callback hook to `Embeddings` abstract base class in `libs/langchain/langchain/embeddings/base.py`.
- [ ] Tweak concrete embeddings implementations in `libs/langchain/langchain/embeddings` as necessary.
One minimally invasive approach would be:
- Implement concrete `embed_documents`, `embed_query`, `aembed_documents`, and `aembed_query` methods on the abstract `Embeddings` base class that contain the embeddings callback hook. Add abstract methods `_embed_documents` and `_embed_query` methods and unimplemented `_aembed_documents` and `_aembed_query` methods to the base class.
- Rename existing concrete implementations of `embed_documents`, `embed_query`, `aembed_documents`, and `aembed_query` to `_embed_documents`, `_embed_query`, `_aembed_documents`, and `_aembed_query`.
### Motivation
Embeddings are useful for LLM application monitoring and debugging. I want to build a callback handler that enables LangChain users to visualize their data in [Phoenix](https://github.com/Arize-ai/phoenix), an open-source tool that provides debugging workflows for retrieval-augmented generation. At the moment, it is not possible to get the query embeddings out of LangChain's callback system, for example, when using the `RetrievalQA` chain. Here is an [example notebook](https://github.com/Arize-ai/phoenix/blob/main/tutorials/langchain_pinecone_search_and_retrieval_tutorial.ipynb) where I sub-class `OpenAIEmbeddings` to get out the embedding data:
```
class OpenAIEmbeddingsWrapper(OpenAIEmbeddings):
"""
A wrapper around OpenAIEmbeddings that stores the query and document
embeddings.
"""
query_text_to_embedding: Dict[str, List[float]] = {}
document_text_to_embedding: Dict[str, List[float]] = {}
def embed_query(self, text: str) -> List[float]:
embedding = super().embed_query(text)
self.query_text_to_embedding[text] = embedding
return embedding
def embed_documents(self, texts: List[str], chunk_size: Optional[int] = 0) -> List[List[float]]:
embeddings = super().embed_documents(texts, chunk_size)
for text, embedding in zip(texts, embeddings):
self.document_text_to_embedding[text] = embedding
return embeddings
@property
def query_embedding_dataframe(self) -> pd.DataFrame:
return self._convert_text_to_embedding_map_to_dataframe(self.query_text_to_embedding)
@property
def document_embedding_dataframe(self) -> pd.DataFrame:
return self._convert_text_to_embedding_map_to_dataframe(self.document_text_to_embedding)
@staticmethod
def _convert_text_to_embedding_map_to_dataframe(
text_to_embedding: Dict[str, List[float]]
) -> pd.DataFrame:
texts, embeddings = map(list, zip(*text_to_embedding.items()))
embedding_arrays = [np.array(embedding) for embedding in embeddings]
return pd.DataFrame.from_dict(
{
"text": texts,
"text_vector": embedding_arrays,
}
)
```
I would like the LangChain callback system to support this use-case.
This feature has been [requested for TypeScript](https://github.com/hwchase17/langchainjs/issues/586) and has an [open PR](https://github.com/hwchase17/langchainjs/pull/1859). An additional motivation is to maintain parity with the TypeScript library.
### Your contribution
I am willing to implement, test, and document this feature with guidance from the LangChain team. I am also happy to provide feedback on an implementation by the LangChain team by building an example callback handler using the embeddings hook. | Add callback support for embeddings | https://api.github.com/repos/langchain-ai/langchain/issues/8564/comments | 2 | 2023-08-01T06:13:53Z | 2023-11-07T16:06:08Z | https://github.com/langchain-ai/langchain/issues/8564 | 1,830,536,926 | 8,564 |

| ### Feature request
Currently, langchain supports petals, but I think we should also support using a petals API endpoint. https://github.com/petals-infra/chat.petals.dev
### Motivation
The idea here is that users don't need to run the base application on their system, and can just use the API directly.
I think this is useful as a developer for speed, and just testing things quickly. I also think it would be the easiest and most reliabile way for any langchain user to get access to a high quality LLM on low-spec hardware.
### Your contribution
I am happy to add this myself if I can be guided on what parts of the code need changed. | Petals API Support | https://api.github.com/repos/langchain-ai/langchain/issues/8563/comments | 2 | 2023-08-01T05:38:35Z | 2023-11-28T11:01:45Z | https://github.com/langchain-ai/langchain/issues/8563 | 1,830,501,646 | 8,563 |

| ### Feature request
Most databases include comment metadata on both tables and columns in a table. It would be nice to be able to pass this additional context to the LLM to get a better response.
The implementation could include adding two parameters to the [SQLDatabase](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/utilities/sql_database.py) object. For example:
- `table_metadata_sql` (perhaps `table_comment_sql`) runs a query and expects a table with two columns `table_name` and `comment`
- `column_metadata_sql` (perhaps `column_comment_sql` runs a query and expects a table with three columns `table_name`, `col_name`, and `comment`
Perhaps these two params could be combined into a single `metadata_sql` which returns for column table with `table_name`, `table_comment`, `column_name`, and `column_comment`
### Motivation
The main motivation behind this is to provide the LLM additional context beyond the CREATE TABLE and sample rows. Although this will be a more costly request (more tokens), I believe in many instances will lead to better SQL being generated. I also want to encourage better documentation of database objects in the data warehouse or data lake.
### Your contribution
Happy to submit a PR for this. Please weigh in on any design decisions:
- how many parameters to use 1 or 2?
- where to include the comments in the prompt, part of the CREATE TABLE as SQL comments? | Add metadata parameter(s) to SQLDatabase class | https://api.github.com/repos/langchain-ai/langchain/issues/8558/comments | 2 | 2023-08-01T01:08:42Z | 2023-11-07T16:06:18Z | https://github.com/langchain-ai/langchain/issues/8558 | 1,830,288,016 | 8,558 |

Background
I'm using Azure Cognitive Search as my vector store. In `azuresearch`, if you call `addtexts` with no metadata, you get an exception

1. create AzureSearch object
2. call `add_texts` without specifying the metadata parameter
3. You'll get an error

So It's possible to parse "complex" objects with

ResponseSchema(name="place", description="The place where the event will happen"),
]
output_parser = StructuredOutputParser.from_response_schemas(response_schemas)
```
and
```python
class Pair_of_numbers(BaseModel):
L: int = Field(description="A number")
R: int = Field(description="A number that ends in 2, 3 or 4")
@validator("R")
def question_ends_with_question_mark(cls, field):
if int(str(field)[-1]) not in [2, 3, 4]:
raise ValueError("No bro :(")
return field
parser = PydanticOutputParser(pydantic_object=Pair_of_numbers)
```
But I can't seem to find information on how to parse a list of custom objects/dicts? There is the [list parser](https://python.langchain.com/docs/modules/model_io/output_parsers/comma_separated), but this is just for simple strings.

### Reproduction
There is the minimal produce demo
```python
from langchain.chat_models import PromptLayerChatOpenAI
from dotenv import load_dotenv
load_dotenv()
import promptlayer
from langchain.schema import HumanMessage
promptlayer.api_key = "xxxxxxxxxxx"
llm = PromptLayerChatOpenAI(model="gpt-3.5-turbo", verbose=True, pl_tags=["test"])
print(llm([HumanMessage(content="I am a cat and I want")]))
```
I found it on the [**PromptLayer**](https://promptlayer.com/)
<img width="978" alt="image" src="https://github.com/langchain-ai/langchain/assets/3949397/770f6c3f-ec8a-42df-967d-8e207b3208d4">
### Expected behavior
Why is the API key carried in this PromptLayer? This is insecure, it should be removed. Then, I discovered the root of the problem
The paras are generated from this function (**_generate** and **_agenerate**).
And I got it inherit from **ChatOpenAI** model function __create_message_dicts_ and __client_params_, then I found the api_key
https://github.com/langchain-ai/langchain/blob/08f5e6b8012f5eda2609103f33676199a3781a15/libs/langchain/langchain/chat_models/openai.py#L487
but the api_key is necessary for ChatOpenAI model to get the result.
so it should be changed with this two line

### Reproduction
tried to load https://huggingface.co/TheBloke/StableBeluga2-70B-GGML model to work with lanchain's Llamacpp :
`llm = LlamaCpp(model_path="./stablebeluga2-70b.ggmlv3.q4_0.bin", n_gpu_layers=n_gpu_layers,
n_batch=n_batch, n_ctx=8192, input={"temperature": 0.01},n_threads=8)
llm_chain = LLMChain(llm=llm, prompt=prompt)`
i see that there is no support in passing n_gqa=8 parameter that according to [https://github.com/abetlen/llama-cpp-python](https://github.com/abetlen/llama-cpp-python) should be used for 70B models
the error i get is :
error loading model: llama.cpp: tensor 'layers.0.attention.wk.weight' has wrong shape; expected 8192 x 8192, got 8192 x 1024
### Expected behavior
model should be loaded successfuly | no support for loading 70B models via llamacpp | https://api.github.com/repos/langchain-ai/langchain/issues/8486/comments | 3 | 2023-07-30T09:12:42Z | 2023-11-07T16:06:33Z | https://github.com/langchain-ai/langchain/issues/8486 | 1,827,863,684 | 8,486 |

| ### Feature request
I propose the addition of a foundational chain feature, namely, the IteratorChain to LangChain. Unlike a convenience function, this feature is intended to enhance the flexibility and usability of LangChain by allowing it to handle collections of inputs for any existing chain, propagating them sequentially or asynchronously.
```python
from langchain.chains import IteratorChain, LLMChain
llm_chain = LLMChain(...)
iterator_chain = IteratorChain(llm_chain)
inputs = [{"text": "Hello"}, {"text": "World"}]
outputs = iterator_chain.run(inputs)
```
In the current LangChain framework, when dealing with lists or collections of inputs, developers are required to manually loop through the input list and call the run method for each item. This approach not only results in more code but also creates challenges with LangChain's features like LangSmith logging, especially when lists are dynamically generated from previous chains.
The IteratorChain would encapsulate this looping, resulting in cleaner code and better integration with LangSmith logging and other LangChain features.
### Motivation
The proposed IteratorChain could address a current issue I'm having when dealing with nested lists of inputs. Let's consider the current SequentialChain setup below:
```python
SequentialChain(
chains=[
ChainA(input_variables=["inputA"], output_key="outputA"),
TransformChain(input_variables=["outputA", "auxiliary_input"], output_variables=["outputB"], transform=process_A_to_B),
TransformChain(input_variables=["outputB", "auxiliary_input"], output_variables=["outputC"], transform=refine_B_to_C),
TransformChain(input_variables=["outputC", "auxiliary_input"], output_variables=["final_output"], transform=process_C_to_final)
],
input_variables=["inputA", "auxiliary_input"],
output_variables=["final_output"]
)
```
In this setup, process_A_to_B and refine_B_to_C are both creating lists of inputs for further chains. However, these lists of inputs are currently not being processed elegantly. We have to loop manually over the list and call the underlying chain for each item. This not only leads to cumbersome code, but also hinders proper interaction with the LangSmith logging feature.
```python
def process_A_to_B(params) -> List[Dict[str, Any]]:
...
for item in items:
chainB = SomeChain(...)
output = chainB.run({"input": item, "auxiliary_input": auxiliary_input})
...
return {"outputB": outputs}
```
```python
def refine_B_to_C(params) -> List[Dict[str, Any]]:
...
for item in items:
chainC = AnotherChain(...)
output = chainC.run({"input": item, "auxiliary_input": auxiliary_input})
...
return {"outputC": outputs}
```
The addition of an IteratorChain feature would address these issues. It will encapsulate the manual loop and make the list handling process more intuitive and efficient, ensuring proper integration with LangSmith logging and other LangChain features.
### Your contribution
I'm prepared to contribute to the development of this feature, if decided that it is a good addition and is not already possible using existing capabilities. | IteratorChain | https://api.github.com/repos/langchain-ai/langchain/issues/8484/comments | 2 | 2023-07-30T07:43:44Z | 2023-11-05T16:04:59Z | https://github.com/langchain-ai/langchain/issues/8484 | 1,827,840,103 | 8,484 |

```python
sitemap_loader = SitemapLoader(
web_path="https://langchain.readthedocs.io/sitemap.xml",
https_proxy="https://my.proxy.io/"
)
docs = sitemap_loader.load()

### Expected behavior
In [trace-agent/iminder/tools.py](https://github.com/eunomia-bpf/trace-agent/blob/main/iminder/tools.py), I have defined two custom tools: one is called `sample`, and the other is called `analyse_process`. Both tools have only one input parameter, but of different types. `sample` takes an integer as input, while `analyse_process` takes a string. Strangely, `sample` works as expected, but `analyse_process` does not. My expectation was that both of them would function correctly. | Object of type 'FieldInfo' is not JSON serializable | https://api.github.com/repos/langchain-ai/langchain/issues/8448/comments | 2 | 2023-07-29T04:47:30Z | 2023-07-29T08:50:24Z | https://github.com/langchain-ai/langchain/issues/8448 | 1,827,317,440 | 8,448 |

### Reproduction
I checked the recent update for summarization pipeline with memory as:
```
from langchain.llms import HuggingFacePipeline
from transformers import AutoModelForSeq2SeqLM, AutoTokenizer, pipeline
from langchain.memory import ConversationSummaryBufferMemory
import torch
summarize_model = AutoModelForSeq2SeqLM.from_pretrained("facebook/bart-large-cnn", device_map="auto", torch_dtype=torch.bfloat16, trust_remote_code=True)
summarize_tokenizer = AutoTokenizer.from_pretrained("facebook/bart-large-cnn", padding_side="left")
pipe_summary = pipeline("summarization", model=summarize_model, tokenizer=summarize_tokenizer) #, max_new_tokens=500, min_new_tokens=300
hf_summary = HuggingFacePipeline(pipeline=pipe_summary)
memory=ConversationSummaryBufferMemory(llm=hf_summary, max_token_limit=10)
```
Then, added chat history to the memory and observed the memory afterwards as:
```
memory.save_context({"input": "hi"}, {"output": "whats up"})
memory.save_context({"input": "not much you"}, {"output": "not much"})
memory.save_context({"input": "what's my name"}, {"output": "AJ"})
memory.load_memory_variables({})
```
It returned:
```
{'history': "System: The human asks what the AI thinks of artificial intelligence. The AI thinks artificial intelligence is a force for good because it will help humans reach their full potential. Progressively summarize the lines of conversation provided, adding onto the previous summary returning a new summary. The human asks the AI: Why do you think artificial Intelligence is a Force for good? The AI: Because artificial intelligence will help human reach their potential.\nHuman: what's my name\nAI: AJ"}
```
This doesn't summarize the actual chat history, but returns a generalized text: `The human asks what the AI thinks of artificial intelligence. The AI thinks artificial intelligence is a force for good because it will help humans reach their full potential. Progressively summarize the lines of conversation provided, adding onto the previous summary returning a new summary. The human asks the AI: Why do you think artificial Intelligence is a Force for good? The AI: Because artificial intelligence will help human reach their potential.`
### Expected behavior
This would pass wrong prompt to the LLM for question-answering.

| ### Issue you'd like to raise.
I'm trying to load some documents, powerpoints and text to train my custom LLm using Langchain.
When I run it I come to a weird error message where it tells I don't have "tokenizers" and "taggers" packages (folders).
I've read the docs, asked Langchain chatbot, pip install nltk, uninstall, pip install nltk without dependencies, added them with nltk.download(), nltk.download("punkt"), nltk.download("all"),... Did also manually put on the path: nltk.data.path = ['C:\Users\zaesa\AppData\Roaming\nltk_data'] and added all the folders. Added the tokenizers folder and taggers folder from the github repo: [](https://github.com/nltk/nltk_data/tree/gh-pages/packages). Everything. Also asked on the Github repo. Nothing, no success.
Here the code of the file I try to run:

| ### Issue you'd like to raise.
My Chatbot is fairly straight forward. It uses MosaicMLInstructorEmbeddings() as the embedding and MosaicML() as the model. I have a file that I want to retrieve from. When outputting an answer, for instance:
What is AliBi?
It will give a response like:
Answer: LiBi (Attention with Linear Biases) dispenses with position embeddings for tokens in transformer-based NLP models, instead encoding position information by biasing the query-key attention scores proportionally to each token pair’s distance. ALiBi yields excellent extrapolation to unseen sequence lengths compared to other position embedding schemes. We leverage this extrapolation capability by training with shorter sequence lengths, which reduces the memory and computation load.
Or when I give it:
Answer: arded checkpointing is a feature in distributed systems that allows for the checkpointing of the state of the system to be divided into multiple shards. This is useful for systems that have a large amount of data or compute to perform.
I have noticed that the chatbot fairly consistently drops the first or first two characters and I'm wondering if this is a bug with LangChain, MosaicMLInstructorEmbeddings, or MosaicML.
Here is my chatbot file:

I have added the tools named A_tool, default_tool to a `ZeroShotAgent`.
The output from one of the execution looks like:
```
Thought: We need to use the A_tool.

Observation: Use A_tool is not a valid tool, try another one.
Thought:We need to use the default_tool since A_tool is not a valid tool.
Action: Use default_tool
Action Input: None
Observation: Use default_tool is not a valid tool, try another one.
```
I am not sure why the prefix `Use ` is getting added to Action.....ideally action should be just the name of the tool [`A_tool`,` default_tool`]
This is causing InvalidTool to be invoked again and again.

As far as I understood the langchain documentation [(https://python.langchain.com/docs/modules/chains/foundational/sequential_chains)]
the output_key must be defined for each LLM hit for the model to tag the response to that key, hence here I have provided the output key to the agent through the llm_chain.output_key property. But still the code throws error that output variables were not found.
Is this a bug in langchain while binding the csv agents to SequentialChain class or am I missing something? Can someone please help?

| ### Feature request
I'm interested in the code segmenters created. So far we have python and javascript. I'm looking for a typescript one in particular, the JS one marks my typescript as invalid. But in general, having the language support shown in the text splitter Language enum would be ideal but with full on parsing.
### Motivation
This call is ok to start:
`RecursiveCharacterTextSplitter.get_separators_for_language(Language.JS)`
but when we're splitting by the word function we're cutting off `export async` or `default`, and especially JsDoc, which is probably the best think to start a chunk of a function with.
Splitting by keywords like this is kinda clunky as a long term solution because of the above cases and others, having something that's more carefully splitting files up would be better.
### Your contribution
Maybe instead of a parser like eprisma, there's just a generic one that's powered by an LLM. | Add more CodeSegmenters | https://api.github.com/repos/langchain-ai/langchain/issues/8405/comments | 3 | 2023-07-28T06:06:12Z | 2024-02-13T16:45:52Z | https://github.com/langchain-ai/langchain/issues/8405 | 1,825,765,474 | 8,405 |

| ### Issue you'd like to raise.
Hello, I'm currently using the load_summarize_chain function to summarize extensive documents, specifically those about 250 pages or more. In this process, I'm employing the map_reduce chain type along with a custom prompt.
The process works as follows:
In the initial step, the chain sends parallel requests to LLM to summarize chunks of data.
Upon receiving all responses, the summary chain collects them, combines them into a single prompt, and generates the final output.
I'm curious about two aspects of this process:
In the second step, the chain employs the StuffDocumentsChain method to create the final summary despite setting mapreduce in chaintype. Is it possible to use an alternative chain type for this? If yes, could you recommend any?
Would it be feasible to utilize different Language Learning Models (LLMs) in the two steps? For instance, could I use GPT3.5 for the first step and GPT4 for generating the final summary?
I appreciate your help and look forward to your response.

The above shows my introduction of async from before not having it.
The text generation inference server is set to have a large concurrency, but is showing requests are coming in back-to-back.
### Expected behavior
I expect the summarization part to be parallel, like stated here:
https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/chains/combine_documents/map_reduce.py#L210-L213
But perhaps I misunderstand something. Or perhaps it's not really parallel:
https://github.com/langchain-ai/langchain/issues/1145#issuecomment-1586234397
There's lots of discussion w.r.t. hitting rate limit with OpenAI:
https://github.com/langchain-ai/langchain/issues/2465
https://github.com/langchain-ai/langchain/issues/1643
So I presume this works, but I'm not seeing it. In OpenAI case it seems to be done via batching, which is possible in HF TGI server but not implemented. But I would have thought that all the reduction tasks could have been in parallel with asyncio.

I have tried both version, and the information by "input_doc" is not reflected in result1. I looked up in example, and I didn't find example where both "retriever" and "input_documents" are used together, it is either this OR that.

| ### Feature request
An integration of exllama in Langchain to be able to use 4-bit GPTQ weights, designed to be fast and memory-efficient on modern GPUs.
### Motivation
The benchmarks on the official repo speak for themselves:
https://github.com/turboderp/exllama#results-so-far
### Your contribution
There is a fork that uses exllama with langchain here :

| ### Feature request
This is related to [HyDE](https://python.langchain.com/docs/modules/chains/additional/hyde). But I feel my feature request puts the HyDE example in a more realistic context, and naturally extends the RetrievalQA chain.
My suggestion would be allow the text passed to the retriever to be different from the query passed to the LLM. This would be useful as fallback when the original query, as provided by the user, yields a response of "I don't know" from the LLM; or if it returns no or poor-scoring documents during the retrieval step.
Step 1, Embed original query
Step 2, retrieve candidate documents based on embedded original query
Step 3, pass original query & retrieved documents to LLM for answer
If Step 2 yields 0/low score documents OR Step 3 yields no/low confidence answer...
Step 4, generate an alternate _hypothetical_ answer (i.e., as described in [HyDE](https://arxiv.org/abs/2212.10496)
Step 5, embed _hypothetical_ answer
Step 6, retrieve candidate documents based on embedded _hypothetical_ answer
Step 7, pass original query & _newly_ retrieved documents to LLM for answer
### Motivation
Perhaps I have a query that does not yield good retrieval documents from my main knowledgebase corpus. It is poorly formed, it has spelling errors, it is vague, it is brief. Even though the corpus does contain the factual answer to the intent of the query. Instead, a different form of the original query would yield better retrieved documents, and therefore produce the correct & complete answer desired.
For example, very simple questions like "Who's Character X?" may yield a wide range of sub-optimal documents from a QA Retriever. As a result, the LLM's response may be muddled or impossible to generate.
### Your contribution
Happy to refine the suggestion and provide concrete examples. | RetrievalQA: Submit different queries to Retriever and LLM | https://api.github.com/repos/langchain-ai/langchain/issues/8380/comments | 3 | 2023-07-27T20:32:27Z | 2023-10-27T16:18:45Z | https://github.com/langchain-ai/langchain/issues/8380 | 1,825,171,219 | 8,380 |

### Expected behavior
It should be possible to do this. The VertexAI Python SDK supports it with the `endpoint.find_neighbors` function.
I think just changing [the wrapper](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/vectorstores/matching_engine.py#L178) from `.match` to `.find_neighbors` for when the endpoint is public should do it.

Numexpr's evaluate function that Langchain uses [here](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/chains/llm_math/base.py#L80) in the LLMMathChain is susceptible to arbitrary code execution with eval in the latest released version. See this [issue](https://github.com/pydata/numexpr/issues/442) where PoC for numexpr's evaluate is also provided.
This vulnerability allows an arbitrary code execution, that is to run code and commands on target machine, via LLMMathChain's run method with the right prompt. I'd like to ask the Langchain's maintainers to confirm if they want a full PoC with Langchain posted here publicly.

### Reproduction
Issue was reported before, see [issue 5428](https://github.com/langchain-ai/langchain/issues/5428)
It is still not solved.
The problem is the regular expression used in libs/langchain/langchain/output_parsers/json.py
```python
match = re.search(r"```(json)?(.*?)```", json_string, re.DOTALL)
```
`.*?` does non-greedy matching, so the parsing does not stop at the final triple backticks, but
at the first occurrence of triple backticks which can be the start of a code section like ```python
Which leads errors like:
`Error while running agent: Could not parse LLM output: json { "action": "Final Answer", "action_input": "Here is a simple Python script that includes a main function and prints 'Hello':\n\npython\ndef say_hello():\n print('Hello')\n\ndef main():\n say_hello()\n\nif name == 'main':\n main()\n```\nThis script defines a function say_hello that prints the string 'Hello'. The main function calls say_hello. The final lines check if this script is being run directly (as opposed to being imported as a module), and if so, calls the main function." }`
### Expected behavior
Correct LLM output parsing for answers including code sections.

| ### Feature request
Some kind of possibility to make a custom tool with return direct not do so when faced with a error such as a ToolException.
### Motivation
Currently, when a tool with return_direct faces a handled error, it returns the error directly. I would want a tool to return an output directly but only if there are no errors, since the errors aren't useful to be directly returned.

I am not sure how this could be implemented, but would gladly help working on any ideas.

It feels strange to use the toolkit but being blind, we cannot see what the agent is doing. The original idea is that by taking screenshoot we could use agents to perform UI testing.

I could help writing a PR, but I’ll need help from the Playwright community.

My goal is to extend the tools used by baby AGI, more specifically to use at least the basic WriteFileTool() and ReadFileTool(). They use two inputs though, so I cannot stick with the vanilla ZeroShotAgent. So i resorted to using: AgentType.STRUCTURED_CHAT_ZERO_SHOT_REACT_DESCRIPTION and replace it in the original code in the link below. Agent initialization is the only modification I've made. Can anyone kindly help me understand what I'm missing in the code in order to be able to leverage multiple input tools or provide guidance/resources?

@hwchase17
The RDFGraph class appears to throw an exception when an OWL ontology contains a Restriction.
For example, a Turtle ontology contains the following restriction causes the error "Unexpected IRI 'n16c4af590.........", contains neither '#' nor '/'
```
:Topping rdf:type owl:Class ;
rdfs:subClassOf :Object ,
[ rdf:type owl:Restriction ;
owl:onProperty :hasTopping ;
owl:someValuesFrom :Topping
] .
```
Theis exception occurs in the code:
```
graph = RdfGraph(
source_file="example.ttl",
serialization="ttl",
standard="owl"
)
```
This appears to happen because the rdflib library inserts necessary blank nodes when it reads an ontology.

| ### Feature request
I propose to make BaseMemoryAsync, BaseChatMessageHistoryAsync, SummarizerMixinAsync, BaseChatMemoryAsync and add support for async save_context to the main Chain class. For web development, everything is asynchronous, and this is critical.
### Motivation
I've faced a problem when writing a chatbot using the asynchronous aiogram library, I can't use Memory asynchronously, so I want to add additional classes that support asynchronous memory work. I am using asynchronous sqlalchemy and cannot work with memory. Besides, I think this is a really critical feature.
### Your contribution
I tried to implement this, but it turned out to be too difficult, so I'm asking you very much, give me and other people the opportunity to work with memory asynchronously. | Async Memory | https://api.github.com/repos/langchain-ai/langchain/issues/8329/comments | 1 | 2023-07-27T00:31:00Z | 2023-11-02T16:05:19Z | https://github.com/langchain-ai/langchain/issues/8329 | 1,823,401,369 | 8,329 |

| ### Issue you'd like to raise.
This might be a general issue with LLM tools but I wanted to pose it here since this community is very active.
When you feed a huge CSV file with thousands of comments, you are trying to summarize them but also extract some quotes.
When feeding this file into Langchain, it will summarize just fine. However, the quotes will get lost when reducing the result. The quotes will end up being summarized and lose their data integrity
Is there a way around this issue? Can this solved by tweaking the system prompt?

| ### Feature request
Add support for passing CustomAttributes to the `SagemakerEnpiontLLM` wrapper around `client.invoke_enpoint()`
With the release of LLama-v2 on Sagemaker Jumpstart, we are required to pass EULA=TRUE # END USER LICENSE AGREEMENT
Endstate
```python
class SagemakerEndpoint(LLM):
...
...
custom_attributes: Dict
custom_attributes =
# send request
try:
response = self.client.invoke_endpoint(
EndpointName=self.endpoint_name,
Body=body,
ContentType=content_type,
Accept=accepts,
Custom_Attributes=self.custom_attributes
**_endpoint_kwargs,
)
except Exception as e:
raise ValueError(f"Error raised by inference endpoint: {e}")
```
### Motivation
Lanchain is incompatible with llama-v2 model using SagemakerEnpointLLM in langchain
without the fix, Lanchain throws an error

| ### Issue with current documentation:
I am converting from CONVERSATIONAL_REACT agent to Functions and having a tough time figuring out how to customize the prompt. Memory was not obvious, but worked as expected. However, adding additional inputs does not:
``` Python
memory = ConversationBufferMemory(memory_key="chat_history", return_messages=False)
template = """
The Human is named {user_name}. Always answer questions by directing it at the Human by name.
For example, if the Human asks "What is the weather like?", you should answer "It is sunny, {user_name}." instead of just "It is sunny.".
History of the conversation:
{chat_history}
"""
extra_prompt = SystemMessagePromptTemplate.from_template(
template=template,
input_variables=["chat_history", "user_name"],
)
agent_args = {
"extra_prompt_messages": [extra_prompt],
}
mrkl_chat = initialize_agent(
tools,
llm,
agent=AgentType.OPENAI_MULTI_FUNCTIONS,
memory=memory,
agent_kwargs=agent_args,
verbose=True,
)
```
This works, but trying to run using
``` Python
mrkl_chat.run(input="What is fity six times twenty seven?", user_name="John")
```
executes the function call correctly, but then errors:
```
ValueError: One input key expected got ['input', 'user_name']
```
How do I pass in the extra inputs?

| ### Feature request
Hi,
this repo on huggingface implements word-level timestamps into locally run whisper models: https://huggingface.co/spaces/Matthijs/whisper_word_timestamps/tree/main
I have created a simple modification of this for generating simple CSVs with words and timestamps, a functionality i'd love to see in langchain too: https://github.com/SimonB97/whisper-word-ts-csv (currently only running with cuda support, but should be modifiable to dynamically support both cpu and gpu).
### Motivation
It would be amazing to be able to generate word-level timestamps together with transcriptions, for example to be able to pin-point when some information in a youtube video was given.
### Your contribution

| ### Feature request
According to the [Amazon Kendra documentation](https://docs.aws.amazon.com/kendra/latest/APIReference/API_Query.html), a query response contains three types of results:
- **Relevant suggested answers.** The answers can be either a text excerpt or table excerpt. The answer can be highlighted in the excerpt.
- **Matching FAQs** or questions-answer from your FAQ file.
- Relevant documents. This result type includes an excerpt of the document with the document title. The searched terms can be highlighted in the excerpt.
Therefore, the AmazonKendraRetriever should be flexible to allow a retrieval pattern that combines the query API with the retrieve API or not.
For instance, the application could:
- use the query API to check for relevant answers or matching FAQs before calling another retriever with the retrieve API;
- explore the [Merger Retriever](https://python.langchain.com/docs/integrations/retrievers/merger_retriever) to combine the results of the retrieve and query APIs.
### Motivation
Currently, the AmazonKendraRetrieve uses the retrieve API by default and fall backs to the query API in case the retrieve API results are empty.
### Your contribution
I could submit a PR. | In the AmazonKendraRetriever, allow selection of which API to use: query or retrieve (default) | https://api.github.com/repos/langchain-ai/langchain/issues/8315/comments | 2 | 2023-07-26T19:22:38Z | 2023-11-01T16:05:00Z | https://github.com/langchain-ai/langchain/issues/8315 | 1,823,016,792 | 8,315 |

| ### Feature request
Possibility to make a direct return of a tool's output on certain cases.
### Motivation
Under specific circumstances, it would be extremely beneficial to be able to return a tool's output directly to the user. For instance, this feature would be helpful when using a search tool. If a search made no matches, a response can be directly sent to the user. Without being able to make a direct return, the tool's output is sent to the LLM, making the LLM prone to hallucinate the final answer.

| ### Issue you'd like to raise.
I have defined several Chains (LLM Chains, RetrievalQA and ConversationalRelationChain) and have used an agent to route between them after I created for each their respective Tool.
I realised that when each chain was defined outside of the agent, their performance was amazing. But once you add them up as routes in the agent, their performance drops significantly.
The exact same questions that they manage to answer to outside of the routing system (agent) are answered incorrectly when used as a route in the Agent.
Is anyone else facing this issue or is it only me? Is it fixable?

### Reproduction
I try using a local LLM from HuggingFace:
1. Using from_model_id works perfectly:
llm = HuggingFacePipeline.from_model_id(
model_id="TheBloke/wizardLM-7B-HF",
task="text-generation",
pipeline_kwargs={"max_new_tokens": 1200, "temperature": 0.3, "top_p": 0.95, "repetition_penalty": 1.15,},
device=0,
)
print(llm)
Params: {'model_id': 'TheBloke/wizardLM-7B-HF', 'model_kwargs': {}, 'pipeline_kwargs': {'max_new_tokens': 1200, 'temperature': 0.3, 'top_p': 0.95, 'repetition_penalty': 1.15}}
2. Now the problem is when **passing pipeline directly**:
I just followed the example given in Langchain.
from langchain.llms import HuggingFacePipeline
from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
import transformers
model_id = "TheBloke/wizardLM-7B-HF"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, trust_remote_code=True)
pipe = pipeline(
"text-generation",
model=model,
tokenizer=tokenizer,
device_map="auto",
max_new_tokens = 1200,
temperature = 0.3,
top_p = 0.95,
repetition_penalty = 1.15,
)
hf = HuggingFacePipeline(pipeline=pipe)
print(hf)
### Now I get this: Params: {'model_id': 'gpt2', 'model_kwargs': None, 'pipeline_kwargs': None}
### Expected behavior
What is the matter?
Why are the paramters that I set not taken?
Why does it use the default ones?
I tried it now over and over and over again, but I can't get it work.
Sb has any idea why? I am a bit desperate, cause I need to pass pipeline directly.
Official langchain documentation:
Example passing pipeline in directly:
from langchain.llms import HuggingFacePipeline
from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
model_id = "gpt2"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)
pipe = pipeline(
"text-generation", model=model, tokenizer=tokenizer, max_new_tokens=10
)
hf = HuggingFacePipeline(pipeline=pipe)

### Reproduction
As mentioned in the readme if .devcontainer
1. Clone locally
2. In Vscode select Build and open in dev container
### Expected behavior
The Devcontainer is working well, Building and running
but the mounted folder is incorrect and empty, so the vscode file explorer is empty
Maybe due to the devcontainer.json file, referring to a FolderBaseName variable

| ### Issue you'd like to raise.
Hi, it's my first issue in github. And the first thing I want to say is that LangChain is awesome!
I'm not quite so sure is that a bug or just a little issue of config.So I list it as a other issue.
I built a agent and built some RetrievalQA chains as tools for agent.However,when I ask a question,agent answer my question in a sentence and make up some new QAs, which easily misdirected agent and made final answer quite irrelevant with my original question.
So is that my problem in config of agent or LLM(temperture/prompt), or do i need to adjust my agent?(But I have tried to add `early_stopping_method` and `max_execution_time` to limit the agent generate redundant content.And turns out it didn't work well)
### Suggestion:
Maybe add some solution in document? | Issue: LLM makes up new QAs after answering question in a QA chains | https://api.github.com/repos/langchain-ai/langchain/issues/8273/comments | 4 | 2023-07-26T07:34:35Z | 2023-11-02T16:16:04Z | https://github.com/langchain-ai/langchain/issues/8273 | 1,821,769,394 | 8,273 |

The DATA for this decision are as follows:

| Hi , I am using an existing open search vector store and trying to perform below queries using langchain and python. But i am unable to see the documents returned.
Queries:
docs = result.similarity_search(
"show me results for rest API throwing 500 exceptions", search_type="painless_scripting",space_type="cosinesimil",
vector_field="listOfMessages.vectorEmbeddings",
text_field="listOfMessages.messageContent"
)
Note:
1. even if i use other search_type or not pass search_type also i am not getting any results.
2. Here my fields are nested fields.
Someone please help me on how to resolve this issue.
