] | ### Issue with consuming Organizarion Azure OpenAI Token
Hi everyone,
Currently I used https://github.com/hwchase17/chat-your-data for training on a sample data using my personal OpenAI Token and it works properly. But to consume it for our organization we cannot use personal OpenAI Token, instead they have already set up paid subscription of Azure OpenAI Keys hosted within the organization.
The process to generate the token is to make use of a key.json file which consists of the following parameters:
```
{
"vendor": "*****",
"url": "https://azure-openai-serv-*****.com",
"uaa": {
"tenantmode": "dedicated",
"sburl": "https://*****.com",
"subaccountid": "*****",
"credential-type": "binding-secret",
"clientid": "*****|azure-openai-service-*****",
"xsappname": "******|azure-openai-service-******",
"clientsecret": "******",
"url": "https://*****.com",
"uaadomain": "*****.com",
"verificationkey": "-----BEGIN PUBLIC KEY-----\n*****\n-----END PUBLIC KEY-----",
"apiurl": "https://*****.com",
"identityzone": "*****",
"identityzoneid": "******",
"tenantid": "******",
"zoneid": "*****"
}
}
```
Now, using the following parameters, we generate the token using the steps mentioned below:
```
with open(KEY_FILE, "r") as key_file:
svc_key = json.load(key_file)
# Get Token
svc_url = svc_key["url"]
client_id = svc_key["uaa"]["clientid"]
client_secret = svc_key["uaa"]["clientsecret"]
uaa_url = svc_key["uaa"]["url"]
params = {"grant_type": "client_credentials" }
resp = requests.post(f"{uaa_url}/oauth/token",
auth=(client_id, client_secret),
params=params)
token = resp.json()["access_token"]
```
And using this token, we use it like below:
```
data = {
"deployment_id": "gpt-4",
"messages": [
{"role": "user", "content": '''Some question'''}
],
"max_tokens": 800,
"temperature": 0.7,
"frequency_penalty": 0,
"presence_penalty": 0,
"top_p": 0.95,
"stop": "null"
}
headers = {
"Authorization": f"Bearer {token}",
"Content-Type": "application/json"
}
response = requests.post(f"{svc_url}/api/v1/completions",
headers=headers,
json=data)
print(response.json()['choices'][0]['message']['content'])
```
I need help regarding consuming this organization openai key in the python project https://github.com/hwchase17/chat-your-data.
Can you please help how we can use this organizational OpenAi token instead of the personal OpenAI token.

[
"langchain-ai",
"langchain"
] | ### Feature request
About the token_max variable in the "langchain\chains\combine_documents\map_reduce.py" file.
I think the value of token_max should be related to the max_token of the model, rather than setting token_max to 3000.
### Motivation
When I was using the "gpt-3.5-turbo-16k" model, I used the map_reduce chain to process a paper with 30,000 tokens，I always get ValueError
"A single document was so long it could not be combined "
"with another document, we cannot handle this."
I think these are because of the trouble caused by token_max 3000.
When I use a large token model, it is correct that token_max should also be larger.
### Your contribution
I am currently working on my problem by setting token_max to 6000, but this is not perfect, I hope to fix it to dynamically fetch token_max based on different models.

While lock file is necessary for the deployment environment, having a lock file is very hard for creating new integrations, given the fast development pace of the library.
I opened this ticket serving as a discussion on possible alternative solutions to maintaining lock file:
1. Remove it once and for all?
2. Maybe we can have a bot that helps with resolving merge conflicts for lock file specifically ?

"langchain-ai",
"langchain"
] | ### Feature request
I am proposing an enhancement to the Langchain project that will allow the handling of concurrent requests for task workers. This proposal aims to introduce a mechanism similar to the API request parallel processor used in the OpenAI Cookbook.
The implementation should ideally manage several task workers, assigning and executing requests in parallel. This should improve task processing speed and efficiency, especially when dealing with a large number of tasks. You can check the relevant details and example code from [this link](https://github.com/openai/openai-cookbook/blob/main/examples/api_request_parallel_processor.py).
### Motivation
I'm currently using langchain for a project that has a few processes that is very reliant on using Langchain, it is a process that takes hours if done serially, so I rewrote it to be done in parallel but with that I'm hitting rate limits very quickly with Langchain.

### Reproduction
1. Use `CharacterTextSplitter.from_tiktoken_encoder` and set the separator to `" "`, and the chunk size to anything
2. Split some text using `split_text`
3. Notice that the resulting chunked text is nearly half the token length specified by the chunk size
```py
import tiktoken
from langchain.text_splitter import CharacterTextSplitter
lorem_text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Metus dictum at tempor commodo ullamcorper a lacus vestibulum sed. Integer quis auctor elit sed vulputate. Quis blandit turpis cursus in hac. Pellentesque pulvinar pellentesque habitant morbi tristique senectus et netus et."
text_splitter = CharacterTextSplitter.from_tiktoken_encoder(
chunk_size=100, chunk_overlap=0, separator=" ", model_name="gpt-3.5-turbo"
)
texts = text_splitter.split_text(lorem_text)
encoding = tiktoken.encoding_for_model("gpt-3.5-turbo")
print(len(encoding.encode(texts[0]))) # 44 Tokens ; expected around 100
```
### Expected behavior
I would expect the resulting text chunks after splitting to be around 100 tokens.
I think the issue arises from text_splitter.py, commit #1511 : lines 135 and 160. `total += _len + (separator_len if len(current_doc) > 1 else 0)` assumes that the separator (in this case " ") is it's own token, but I think " " is often combined with the characters next to it. From the tokenizer webpage from OpenAI :
You can see that for the " " and "d" from "dolor" are combined into one token, instead of always being separate as assumed by the above `total`. | Text Chunks are 1/2 the token length specified when using split text with CharacterTextSplitter.from_tiktoken_encoder and separator=" " | https://api.github.com/repos/langchain-ai/langchain/issues/6373/comments | 6 | 2023-06-18T17:20:45Z | 2024-01-19T18:36:31Z | https://github.com/langchain-ai/langchain/issues/6373 | 1,762,386,281 | 6,373 |

Allow tweaking with the history window / intermediate actions that are being sent to the LLM:
* Send a sliding window if N last actions
* Only send a specific snapshot (can be useful for code generation tasks - for example where the agent needs to perfect the code until it works).
### Motivation
Currently, agents use the entire length of intermediate actions whenever they call the LLM.
This means that long-running agents can quickly reach the token limit.

When mixing `gpt-3.5-turbo-0613`, `openai-functions` agent, and `PythonAstREPLTool` tool, GPT3.5 stops respecting the tool name and the arguments hack introduced in the OpenAIFunctionsAgent.
The error log is:
```
Could not parse tool input: {'name': 'python', 'arguments': "len(cases_df['case_id'].unique())"} because the `arguments` is not valid JSON.
```
Which means the model isn't respecting the specs accurately. In my case, the confusion was always that the name of the tool is `python` instead of `python_repl_ast`, and the `arguments` is the actual python code instead of the requested obj format with `__arg1` attr.
### Suggestion:
I temporarily fixed it by
1- extending the `OpenAIFunctionsAgent` and overriding the `_parse_ai_message` to handle arguments confusion.
2- extending the `PythonAstREPLTool` and altering its name and description a bit.
```

name = "python"
description = (
"A Python shell. Use this to execute python commands. "
"The input must be an object as follows: "
"{'__arg1': 'a valid python command.'} "
"When using this tool, sometimes output is abbreviated - "
"Make sure it does not look abbreviated before using it in your answer. "
"Don't add comments to your python code."
)

function_name = function_call["name"]
try:
_tool_input = json.loads(function_call["arguments"])
except JSONDecodeError:
print(
f"Could not parse tool input: {function_call} because "
f"the `arguments` is not valid JSON."
)

# The code that encodes tool input into Open AI uses a special variable

Not sure if this will be improved on the API level, but it is worth looking at it.

The current python client `langchain.vectorstores.redis` lacks support for RedisCluster. Handling redirection with try-expect on receiving `MOVED` error also doesn't work in this case because the code `Redis.from_documents(docs, llmembeddings, redis_url=redis_url, index_name=index_name)` internally makes more calls to Redis, which eventually throw MOVED error because the client is not configured for RedisCluster.
### Motivation
As users of Redis Cluster at Salesforce, we aim to integrate it seamlessly and develop a chatbot powered by LLM. Enabling Redis API support in the Vector Redis Client would enhance performance, streamline development workflows, and provide a unified client library for interacting with Redis databases.

result = chain.run(query=self._query)
endTime = time.time()
elapsedTime = endTime - startTime
Globals().logMessage(f'Completed query in {elapsedTime:.3f} seconds'
~~~
### Expected behavior
I'm writing a program that I can load a set of documents into a vector index (FAISS) and then run a
RetrievalQA chain to ask questions about the document(s) I've loaded. I seem to have this working when
I load regular models or GPTQ models, where I'm using HuggingFace APIs to do this.
I have this sort of working where I'm using Langchain APIs to load a LLamaCPP model and then
create and run a RetrievalQA chain to run the query.
I'm doing this as a learning exercise to learn about AI and LLMs, so it's possible I'm doing something
wrong, or maybe I'm running into a philosophical difference between how the HuggingFace APIs work
and how Langchain APIs work.
The problem I am encountering is that it seems that with Langchain, I have to set the model parameters such as temperature, topP, topK, max_tokens, etc at the time I load the model (llamaCppLoader)
and that they are ignored if I specify them when I create and run the RetrievalQA
chain (runLlamaCppQuery).
I noticed this with max_tokens, where if I set it to a small value like 15 when I load the model and
then a larger value like 2000 when I create the RetrievalQA chain. The query result I get is short,
about 15 words, even though I override it to 2000 when I create the RetrievalQA chain.
Maybe this is the way it is supposed to work, but then it seems a bit cumbersome since this
seems to mean I need to reload the model each time I run a new query, while I don't when
using the HuggingFace APIs for the other model types.
Also, if I pass an invalid parameter name when I create the RetrievalQA chain, it does not get
flagged as an invalid parameter. For instance,
```
params['xxx'] = 'junk'
~~~
does not get flagged. | LLamaCPP model seems to require model parameters to be set at model creation, not invocation of chain using model | https://api.github.com/repos/langchain-ai/langchain/issues/6355/comments | 10 | 2023-06-18T01:52:46Z | 2024-01-30T00:45:55Z | https://github.com/langchain-ai/langchain/issues/6355 | 1,762,074,184 | 6,355 |

] | ### Feature request
I propose the integration of a **Docusaurus Document Loader** for the LangChain Python repository. By integrating a **[Docusaurus](https://docusaurus.io/) Document Loader**, we can extend the documentation capabilities of LangChain and provide a more comprehensive resource for developers who use Docusaurus (similar to ReadTheDocs).
### Motivation
My motivation for this feature request is to enhance and extend the document loading functionalities of LangChain. Currently, LangChain [integrates with ReadTheDocs](https://python.langchain.com/docs/modules/data_connection/document_loaders/integrations/readthedocs_documentation), and while this is a powerful tool, incorporating a **Docusaurus Document Loader** can offer an alternative loader. Plus, LangChain docs ([Python](https://python.langchain.com/docs) and [JavaScript)](https://js.langchain.com/docs) are already hosted on Docusaurus.
### Your contribution
As the one initiating this feature request, I am willing to help by creating this issue and providing initial suggestions for the implementation of the **Docusaurus Document Loader**. | Docusaurus Document Loader | https://api.github.com/repos/langchain-ai/langchain/issues/6353/comments | 6 | 2023-06-17T22:37:27Z | 2024-01-25T14:19:08Z | https://github.com/langchain-ai/langchain/issues/6353 | 1,762,019,892 | 6,353 |

HI all,
As can be seen in this screenshot
I am using pandas_df_agent, but instead of taking whole dataframe, which is around 27000 lines, it is creating itself a Sample data, and doing operations on that.
Isn't it weird, ? Kindly help me with this..
Thanks

This issue is created at langchain v0.0.202
Consider the [ListDirectoryTool](https://github.com/hwchase17/langchain/blob/0475d015fe0eb4a997c7d37867e316a23dde8aaa/langchain/tools/file_management/list_dir.py#L21)
Its only parameter has a default value as the `.` current dir.
Its json-schema suggests no parameter is required
```
>>> pprint.pprint(langchain.tools.format_tool_to_openai_function(t))
{'description': 'List files and directories in a specified folder',
'name': 'list_directory',
'parameters': {'description': 'Input for ListDirectoryTool.',
'properties': {'dir_path': {'default': '.',
'description': 'Subdirectory to '
'list.',
'title': 'Dir Path',
'type': 'string'}},
'title': 'DirectoryListingInput',
'type': 'object'}}
```
However calling the `run` function without any parameters creates a runtime error
```python
import langchain
t = langchain.tools.ListDirectoryTool(root_dir="~/misc")
t.run()
```
With this error
```
>>> t.run()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: BaseTool.run() missing 1 required positional argument: 'tool_input'
```
This is not a huge problem but at least it creates an inconsistency expectations by the schema and the `run` function call.
### Suggestion:
If the schema had no required arguments, the run function should not create a runtime error if called without any arguments. At least that would be more expected. | Tools with only default arguments still require a parameter to `run()` | https://api.github.com/repos/langchain-ai/langchain/issues/6337/comments | 1 | 2023-06-17T16:24:00Z | 2023-06-19T02:17:36Z | https://github.com/langchain-ai/langchain/issues/6337 | 1,761,912,722 | 6,337 |

It seems that the library is only supported when the deployment type on AzureOpenAI is an engine. When I try to use a deployment_id which is the new way to deploy models on Azure I can't make it work.
This code works well outside of long-chain. Note that I am not using an engine here, but the deployment_id :
```
openai.api_type = "azure"
openai.api_key = "MYAPIHERE"
openai.api_base = "https://eastus.api.cognitive.microsoft.com/"
openai.api_version = "2023-05-15"
response = openai.ChatCompletion.create(
deployment_id="gpt35",
model="gpt-3.5",
messages=[
{"role": "system", "content": "Assistant is a large language model trained by OpenAI."},
{"role": "user", "content": "Tell me a Joke."}
],
temperature=0.0,
max_tokens=4000,
api_key="MYAPIHERE",
request_timeout=15,
)
print(response['choices'][0]['message']['content'])
```
When I try to use that on langchain AzureOpenAI it doesn't work. I don't know if me doing something wrong or if its the library that doesn't support that.
Here is the code I am using to test langchain on and that doesn't work:
```
from langchain.llms import AzureOpenAI
import os
os.environ["OPENAI_API_TYPE"] = "azure"
os.environ["OPENAI_API_VERSION"] = "2023-03-15"
os.environ["OPENAI_API_BASE"] = "https://eastus.api.cognitive.microsoft.com/"
os.environ["OPENAI_API_KEY"] = "MYAPIKEYHERE"
# Create an instance of Azure OpenAI
# Replace the deployment name with your own
llm = AzureOpenAI(
model_name="gpt-3.5",
deployment_id = "gpt35"
)
print(llm("Tell me a joke"))
```
The error is:
```
Exception has occurred: InvalidRequestError (note: full exception trace is shown but execution is paused at: _run_module_as_main)

```

format_tool_to_openai_function(FileSearchTool())
```

This includes some unnecessary fields like `title` and `description` for the `parameters` and `title` for the `parameters.properties`

### Reproduction
1) Start a uvicorn server at `127.0.0.1:8000` (with your langchain python endpoint).
2) Initialize an agent via the following:
```
agent_chain = initialize_agent(
tools,
self.llm,
agent="conversational-react-description",
verbose=True,
memory=self.memory,
return_intermediate_steps=True,
)
```
3) Call the agent via `agent_chain(inputs={"input": "sample text"})` through the aforementioned endpoint.
4) The agent gets stuck and never responds back. I have not defined a time out.
5) Upon examination, it seems it got stuck inside `_load_session()` in `LangChainTracerV1()` in `/langchain/callbacks/tracers/langchain_v1.py`. It seems the port for localhost being sent by `get_endpoint()` is `8000` (which collides with our `localhost`)?

This adds support for Apache Cassandra's vector search capabilities
(see [CEP-30](https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-30%3A+Approximate+Nearest+Neighbor(ANN)+Vector+Search+via+Storage-Attached+Indexes).
### Motivation
The importance of Vector Search in nowaday's AI/LLM landscape cannot be overstated. As Cassandra is a first-class database and now offers this feature, it is important to allow Cassandra users to be able to integrate seamlessly with LangChain without having to leave their database (and the associated benefits).

] | ### Issue you'd like to raise.
**BACKGROUND:**
We want to assign a personality to the agent. We simultaneously want this agent to be capable of running/selecting/using multiple tools. We tried passing the personality in the "PREFIX". We tried using prompt template.
It didn't really work - it wouldn't stick to the personality for long.
However, when we passed the personality string to the "system" role (through OpenAI's API call), it stuck to the personality much longer.
To pass the personality to the system role, we override your class called OpenAIChat(), like so:
```
class MyOverriddenOpenAIChat(OpenAIChat):
system_message: str = ""
def _default_params(self) -> Dict[str, Any]:
"""Get the default parameters for calling OpenAI API."""
return self.model_kwargs
def _get_chat_params(
self, prompts: List[str], stop: Optional[List[str]] = None
) -> Tuple:
if len(prompts) > 1:
raise ValueError(
f"MyOverriddenOpenAIChat currently only supports single prompt, got {prompts}"
)
# Use the system message here.
messages = [{"role": "system", "content": self.system_message}] + \
self.prefix_messages + [{"role": "user", "content": prompts[0]}]
params: Dict[str, Any] = {**{"model": self.model_name}, **self._default_params()} # Invoking the method here
if stop is not None:
if "stop" in params:
raise ValueError("`stop` found in both the input and default params.")
params["stop"] = stop
if params.get("max_tokens") == -1:
# for ChatGPT api, omitting max_tokens is equivalent to having no limit
del params["max_tokens"]
return messages, params
```
**PROBLEM:**
Since you're not supporting the class OpenAIChat() in later versions (and we do want to upgrade to your latest version), how do we achieve passing a personality to the `system` role via your langchain latest version(s)?
If there is no easy way to pass the personality string to the `system` role via your latest langchain version - what is an alternative route to make a principal agent stick to a personality?
Please advise.

### Reproduction
I use load_summarize_chain with my own map and reduce prompts to process video transcript and receive chapters of the video and json format. In the intermediate steps there is no problem - all documents are processed well as I can see in created chapters. However after reduce last few chapters are missed and cut off like it suddenly stops writing output.
- The bug often appears when processing long videos: 50 minutes and longer (however rarely they processed without problems).
- Without output parser (format instructions) it often don't cut off, but can have problems with format.
- Number of tokens after map in my example fewer than 3000 (e.g. 2462, 2704, 2704) so collapse prompt doesn't help.
- Number of tokens of output after reduce is not that big (e.g. 1057, 755). I have examples of bigger results from smaller videos that worked well.
So it is not that output or input for reduce are too big for prompt, because no error about too many values occurs.
I could not find any other possible reasons for such behavior.
Here the code example:
```
output_parser = PydanticOutputParser(pydantic_object=Chapters)
format_instructions = output_parser.get_format_instructions()
# Unload dict
map_prompt = prompt_config["map_prompt"]
reduce_prompt = prompt_config["reduce_prompt"]
# Initialize templates
map_temp = PromptTemplate(input_variables=["text"], template=map_prompt, partial_variables={"format_instructions": format_instructions})
reduce_temp = PromptTemplate(input_variables=["text"], template=reduce_prompt, partial_variables={"format_instructions": format_instructions})
chain_mapreduce = load_summarize_chain(
llm,
chain_type="map_reduce",
return_intermediate_steps=True,
map_prompt=map_temp,
combine_prompt=reduce_temp,
)
res = chain_mapreduce({"input_documents": docs}, return_only_outputs=True)
```
### Expected behavior

### Reproduction
I managed to implement a `AsyncpgEntityStore` that mimics the `SqliteEntityStore` but uses postgres [asyncpg](https://magicstack.github.io/asyncpg/current/) driver and using it successfully this way:
```
entity_store = await AsyncpgEntityStore.from_connection(conn=conn, schema_name="public",)
memory = AsyncConversationEntityMemory(llm=llm, entity_store=entity_store)
return ConversationChain(llm=llm,
prompt=ENTITY_MEMORY_CONVERSATION_TEMPLATE,
verbose=True,
memory=memory)
```
However the `AsyncpgEntityStore` implementation (see below) overrides `EntityStore` base methods and turns them all into async which is problematic in current implentation of the base Chain, here's why :
the reason is `acall` is calling:
1. `self.prep_inputs`
1.1. which calls `external_context = self.memory.load_memory_variables(inputs)`
1.1.1. which calls `entity_summaries[entity] = self.entity_store.get(entity, "")`
2. `self.prep_outputs`
2.1. which calls `self.memory.save_context(inputs, outputs)`
2.1.1. which calls `self.entity_store.set(entity, output.strip())`
So in my case where the `get` and `set` method of the `self.entity_store` are asynchronous I end up not awaiting them:
I'd need to do:
in 1.1.1. ` entity_summaries[entity] = await self.entity_store.get(entity, "")`
in 2.1.1 `await self.entity_store.set(entity, output.strip())`
So this is why I ended up using a `AsyncConversationEntityMemory` which overrides `ConversationEntityMemory`'s methods `save_context` and `load_memory_variables` and turn them async.
Finally I need to go one step above, the `acall` needs to do ` inputs = await self.aprep_inputs(inputs)` instead of ` inputs = await self.prep_inputs(inputs)` and the same for outputs.
Please see the full compare https://github.com/hwchase17/langchain/compare/master...euri10:asyncpg_memory?expand=1 needed in langchain to make this implementation below work.
Would there be a smarter way to proceed ?

class PyPDFLoader in [document_loaders/pdf.py](https://github.com/hwchase17/langchain/blob/master/langchain/document_loaders/pdf.py) to accept bytes object as well.

When a PDF file is uploaded using a REST API call, there is no specific file_path to load from. The solution can be to use file bytes instead as input parameter.

Allow a way within the source documents to determine if identified text in the map step has relevant information that was extracted or not, as well as find the text that was extracted from the sources.
### Motivation
Currently, when the output returns the source documents, it identifies all of the documents for a retriever. However, in map reduce chain, the map step identifies if the source has any relevant text within the source before the reduce step. This information isn't captured anywhere in the final output. I tried mapping a map_reduce chain which included intermediate steps to identify the map steps so I could process to find if the result is relevant or not, but there was a bug because call/acall used run on the document chain, preventing an input.
I'd like to use this information to reduce the number of sources when I cite what information was captured (e.g. if out of 4 sources, 3 sources had relevant information, only cite those sources.) This will help the reliability of the lineage.

Note that this is a very simply way for everyone to reproduce, by using httpbin.org.
**Why does it happen?**
In the API Chain implementation (chains/api/base.py), api_url is retrieved from api_request_chain and then being used without any validation against the API documentation.
### Expected behavior
**Why is it so bad?**
Anyone who's using the APIChain in a production environment, might (rightly) expect the chain to perform API requests only to endpoints that are described by the API documentation that were provided (it doesn't make sense to do anything else).
To understand how bad it might be, let's consider the following production architecture:
- Microservice A (internal service) is exposing endpoints for providing the current time in different timezones.
- Microservice B is a public facing service that provides users with the option to ask what is the time in a specific city/country. Microservice B is then using langchain APIChain (with API documentation of microservice A's endpoints) to respond to the user's question.
- Microservice C is another internal service that stores and responds with sensitive info on API requests.
In this case, every attacker can do SSRF and retrieve information from microservice C.
Now, of course that in many organizations i would expect to have other protection mechanisms to protect against that (network policy or segmentation, AAA between internal services, etc.), so in many cases this vulnerability will not actually be exploitable. But in many others it might be.
**Expected behavior**
I would expect that at least the default behavior would be that API requests will be done only to URLs that are part of the API documentation. | APIChain: Prompt injection can lead to SSRF / API requests to arbitrary endpoints | https://api.github.com/repos/langchain-ai/langchain/issues/6224/comments | 2 | 2023-06-15T13:18:58Z | 2023-09-21T16:07:41Z | https://github.com/langchain-ai/langchain/issues/6224 | 1,758,824,963 | 6,224 |

### Reproduction
Here is my [gist](https://gist.github.com/alonsosilvaallende/17968208a14994e8285d91abdd79efab) to reproduce the error and my current workaround.
The description of my gist is basically:
1. I followed the [example notebook](https://github.com/hwchase17/langchain/blob/master/docs/modules/agents/agents/examples/openai_functions_agent.ipynb) for OPENAI_FUNCTIONS Agent
2. In the tools, add `python_repl` as follows: `load_tools(['python_repl'])[0]` so that the Tools are modified as follows:
```python
tools = [
Tool(
name = "Search",
func=search.run,
description="useful for when you need to answer questions about current events. You should ask targeted questions"
),
Tool(
name="Calculator",
func=llm_math_chain.run,
description="useful for when you need to answer questions about math"
),
Tool(
name="FooBar-DB",
func=db_chain.run,
description="useful for when you need to answer questions about FooBar. Input should be in the form of a question containing full context"
),
load_tools(['python_repl'])[0]
]
```
### Expected behavior
I expect the agent to run normally, however it gives me the error:
'Python REPL' does not match '^[a-zA-Z0-9_-]{1,64}$' - 'functions.4.name'
Here is my [gist](https://gist.github.com/alonsosilvaallende/17968208a14994e8285d91abdd79efab) to see the error and my current workaround.
If I understand correctly, the agent doesn't like that the name has a space. Indeed, if I redefine `python_repl` as:
```python
Tool(name='Python',
func=python_repl.run,
description='A Python shell. Use this to execute python commands. Input should be a valid python command. If you want to see the output of a value, you should print it out with `print(...)`.'
),
```
the problem disappears. It's a workaround but I expect that either this agent not to have problems with names with spaces or to rename Python REPL as Python_REPL and similarly the other tools as Wolfram_Alpha, etc. | OPENAI_FUNCTIONS agent doesn't accept python_repl or google-search or wolfram-alpha tool | https://api.github.com/repos/langchain-ai/langchain/issues/6209/comments | 4 | 2023-06-15T08:15:08Z | 2023-06-16T10:05:53Z | https://github.com/langchain-ai/langchain/issues/6209 | 1,758,290,677 | 6,209 |

Apparently, when model generates no text (it will depend on a specific set of prompts, messages, NO stopwords is used), Azure OpenAI API responds with something like this:
```
{
"choices": [
{
"finish_reason": "stop",
"index": 0,
"message": {
"role": "assistant"
}
}
],
```
As you can see, "message" doesn't have "content" key at all. And LangChain expects that key to always be there and at one point there will be KeyError that "content" is not available. Not the best implementation of API from AOAI side, but we should handle it and raise some dedicated exception. The good place for it seems to be here: https://github.com/hwchase17/langchain/blob/master/langchain/chat_models/openai.py#L368 , (def _create_chat_result)
I've "fixed" it by doing this:
```
def _create_chat_result(self, response: Mapping[str, Any]) -> ChatResult:
generations = []
for res in response["choices"]:
if "content" not in res["message"]: #<--- checking it it's missing
raise EmptyResponseFromModel()# <---- raising custom exception that I can intercept in the main code and react appropriately
```

] | ### System Info
Version: 0.0.188 (but I don't see any change in the latest master that would fix that)
Python: 3.10
Linux
Problem description:
In one of our environments we have multiple Azure OpenAPI base URLs and have to change them on a fly. We do it by changing LLM within the Chain, basically recreating LLM with the new Base URL, Deployment name and so on, something like this:
```
llm = AzureChatOpenAI(
openai_api_base=api_base,
openai_api_version=api_version,
deployment_name=deployment_name,
openai_api_key=api_key,
openai_api_type="azure",)
```
Unfortunately it doesn't always have an effect, as, apparently most of those parameters are not passed correctly to the OpenAI API, here: https://github.com/hwchase17/langchain/blob/master/langchain/chat_models/openai.py#L294 (def completion_with_retry and def acompletion_with_retry) kwargs don't contain things like base endpoint and so on. It seems to be from some legacy openai implementation when it had to be declared as environmental variable. And basically leads to a situation (time to time, depending on how fast the change is, if concurrently different users use different models, etc.) that base URL will remain the same, while deployment name changes.
To fix this, I simply added:
```
...
retry_decorator = _create_retry_decorator(llm)
try:
kwargs['api_base'] = llm.openai_api_base
kwargs['api_key'] = llm.openai_api_key
kwargs['api_type'] = llm.openai_api_type
kwargs['api_version'] = llm.openai_api_version
kwargs['organization'] = llm.openai_organization if llm.openai_organization else None
except:
pass
@retry_decorator
...
```
As it's inside chat_models and openai supports those arguments for chat models, haven't had any problems with it.

### Reproduction
Steps to reproduce:
1. Have 2 different API Base URLs with different deployment names
2. Create many CoversationChain with AzureChatOpenAI (one per "user" from step#4)
3. Have multiple threads/asyncio (in my specific case, it's behind FastAPI)
4. emulate multiple, parallel calls of CoversationChain.run and then start randomly changing for some user AzureChatOpenAI model pointing to different Base URL and deployment name
5. You will see that some calls will fail, cause deployment name would change but base URL won't (easy to observe by setting logging level to DEBUG)
### Expected behavior
Change of base URL and deployment name should be propagated to the "caller" deterministically and reliably. | On API base URL change, underlying connection doesn't always change. | https://api.github.com/repos/langchain-ai/langchain/issues/6202/comments | 3 | 2023-06-15T06:45:19Z | 2023-10-25T16:08:12Z | https://github.com/langchain-ai/langchain/issues/6202 | 1,758,150,424 | 6,202 |

PR https://github.com/hwchase17/langchain/pull/5058 introduced a change to ElasticVectorSearch from_texts which broke, kind of coincidentally, ElasticKnnSearch from_texts

new_texts = ["This is a new text.", "Elasticsearch is powerful.", "Python is great for data analysis."]
knn_search.from_texts(new_texts, embeddings, elasticsearch_url=elasticsearch_url)

which is a pretty weird error.
This is because https://github.com/cdiddy77/langchain/blob/e74733ab9e5e307fd828ea600ea929a1cb24320f/langchain/vectorstores/elastic_vector_search.py#L294 invokes the __init__ of the calling class, in this case `ElasticKnnSearch` which takes parameters in a very different order.
This calling of the wrong __init__ was always present, but the PR above added a subsequent called to add_texts, which is where the bogus embedding is referenced, causing the exception.

Their model is likely trained to handle functions this way, and will have a lot better support. It also supposedly guarantees json matching the json schema, which can be hard to achieve otherwise.

I followed the steps as described in .github/contributing.md:
1. fork the repo
2. clone the fork
3. `conda create -n langchain python=3.9`
4. `conda activate langchain`
5. `pip install -U pip setuptools`
6. `pip install poetry`
7. `poetry completions bash >> ~/.bash_completion`
8. `poetry config virtualenvs.prefer-active-python true`
9. `poetry install -E all` <-- this command failed to unlock the gnome keyring, so I reran according to [poetry#1917](https://github.com/python-poetry/poetry/issues/1917) below:
10. `PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring poetry install -E all`
11. `make format`
Running `make format` results in the following:
```

`which make` returns a `make` script installed in my conda env bin, with the following contents:
```

sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])

Hi folks! 👋 My name is Brigit, and I'm a PM on the VS Code team working on dev containers and [their open spec](https://containers.dev/). Thank you so much for [adding a dev container to this repo](https://github.com/hwchase17/langchain/pull/4035) and [langchainjs](https://github.com/hwchase17/langchainjs/pull/1241) - these are fantastic scenarios!
As we're actively working improvements to dev containers and their spec, we've made some changes to the best practices we recommend. For instance, we host an updated set of [images](https://github.com/devcontainers/images) and [templates](https://github.com/devcontainers/templates) as part of the spec in the [devcontainers org](https://github.com/devcontainers), rather than in [vscode-dev-containers](https://github.com/microsoft/vscode-dev-containers). It looks like the image in this repo uses the [deprecated vscode-dev-containers image](https://github.com/hwchase17/langchain/blob/master/.devcontainer/Dockerfile#L5), and perhaps it could leverage the [Poetry Feature](https://containers.dev/features) instead of Poetry installation scripts in the Dockerfile.
I also tried building the dev container in this repo both in the VS Code Dev Containers extension and GitHub Codespaces, and it didn't work for me as-is (I was stopped at container build), so I think this would be a great opportunity to ensure the dev container works well for all potential contributors too.
It looks like langchainjs uses an [updated image from the devcontainers org](https://github.com/hwchase17/langchainjs/blob/main/.devcontainer/devcontainer.json#L6), which is great!
### Suggestion:
I'd love to contribute a PR to this repo with an updated dev container (and perhaps with some additional info in the readme or a mini [.devcontainer](https://github.com/hwchase17/langchain/tree/master/.devcontainer) readme), but I wasn't sure the best tests to ensure the repo runs correctly in an updated dev container. Would you be able to share any recommended steps / commands / checks so that I can ensure any dev container updates work well for how folks should be building and running this repo? Info on how you tested and verified the [original PR](https://github.com/hwchase17/langchain/pull/4035) would be a great help too (so I can try the same steps).
Let me know if there's any other info I can provide, and I can also just open a draft a PR if that'd be easiest for discussion. Thanks so much!

### Reproduction
The problem is, I am creating a document collection consisting of 150 documents. However, when I embed them, some documents disappear. I have identified the missing documents by comparing the `bulk_metadatas` variable with the unique values of `patent_embeddings` variable. It shows that some documents are indeed missing from the database. Steps to reproduce.
Load the json file from this [gist ](https://gist.github.com/emilmirzayev/99ef6e641ada53804cbd38015c759ccb)into `bulk_data` variable. Then follow this script:
```python
from langchain.embeddings.openai import OpenAIEmbeddings
from langchain.vectorstores.chroma import Chroma
import numpy as np
from scipy.spatial.distance import cdist
bulk_abstracts = []
bulk_claims = []
bulk_metadatas = []
for firm_result in bulk_data:
print(len(firm_result["results"]))
for patent_data in firm_result["results"]:
abstract = abstract_parser(patent_data["abstractText"])
claim = abstract_parser(patent_data["claimText"])
metadata = str(patent_data["assigneeEntityName"]) + " " + str(patent_data["patentApplicationNumber"])
bulk_abstracts.append(abstract)
bulk_claims.append(claim)
bulk_metadatas.append({"company": metadata})
embeddings = OpenAIEmbeddings(openai_api_key = "Your key",
model="text-embedding-ada-002")
from langchain.text_splitter import CharacterTextSplitter, RecursiveCharacterTextSplitter
text_splitter = RecursiveCharacterTextSplitter(chunk_size=2000, chunk_overlap=200)
save_directory = "hundred_fifty_patent_db"
text_splitter = RecursiveCharacterTextSplitter(chunk_size=2000, chunk_overlap=200)
patent_documents = text_splitter.create_documents(bulk_claims,
metadatas= bulk_metadatas
)
db = Chroma.from_documents(documents = patent_documents,
embedding= embeddings,
persist_directory=save_directory
)
db.persist()
# reloading back
db = None
directory_to_load_from = "hundred_fifty_patent_db"
db = Chroma(persist_directory= directory_to_load_from,
embedding_function=embeddings)
patent_embeddings = db.get(["embeddings"])["embeddings"]
patent_metadatas = db.get(["metadatas"])["metadatas"]
# lets see how many entries we have, its 146
a = [data["company"] for data in bulk_metadatas]
b = list(set(company_patent))
np.setdiff1d(a, b)
```
Output:
```
array(['Colgate-Palmolive Company US12159313',

Recently, we do a few test on the ConversationalRetrievalChain + Memory, and notice that, the customer's question is rephrased by Langchain to a totally different meaning. Anyone knows how to avoid this?
The conversation is to introduce the different package of a mobile plan to the customer. and Customer inputs: **Hi**. However, while it comes to Langchain, this sentence is rephrased to: **What is your estimated monthly usage for data, talktime, and SMS?**
**Code:**
qa = ConversationalRetrievalChain.from_llm(
llm=self.llm, retriever=retriever, combine_docs_chain_kwargs={'prompt': self.QA_PROMPT}, verbose=True)
result = qa({'question': question, 'chat_history': message_history.messages})

Given the following conversation and a follow up question, rephrase the follow up question to be a standalone question, in its original language.

### Reproduction
Discussed this with @nfcampos over slack, but pasting it here for documentation/community discussion to validate this change/issue.
I have switched from JS -> Python version but this issue is valid for both.
When using JS version, I noticed the mapreduce chains combine step decides when it should combine based on the token count sum of the map steps entire prompt, instead of just the outputs. This presented a few issues:
- The point of the map step, as I understood it, is to condense the chunk to eventually be able to fit in the combine prompt, and so gauging when to combine based on summing all map steps’ (input+output) token counts didn’t make sense. This leads to several unnecessary iterations, and much longer run time than if it’s just the map steps’ output tokens being summed, which is what is eventually used in the combine step anyway.
- If the map prompt has large instructions, then it is possible that the sum will never reduce past the threshold (token_max default is 3000). Example:
- You have ten chunks having the map step being run.
- Each chunk has 400 token instructions in map Prompt. 400*10= 4000 tokens.
- The map steps would never condense enough to drop below the 3000 token limit, even though the output from each map step might be 100 tokens. Worse still, it would run up $$$ by running map steps until max_iterations.
I can share my monkey patch of the langchain JS code if it helps, and had even proposed a PR for this in the langchianjs discord. Now that we moved to python, and since I haven’t contributed to any python projects, I thought I’d check here before proposing this change or even attempting a PR.
My questions before proceeding are - does this sound right to you? Is there any reason why a generic mapreduce chain would use the entire map prompt from the map step, and not just the outputs when deciding to combine?
### Expected behavior
The map_prompt output tokens should only be summed up when deciding if we can combine or not.
In the JS version, my monkey patched langchain MapReduce chain's implementation looked like:
```
async _call(values) {
if (!(this.inputKey in values)) {
throw new Error(`Document key ${this.inputKey} not found.`);
}
const { [this.inputKey]: docs, ...rest } = values;
let currentDocs = docs;
let totalIterations = 0;
for (let i = 0; i < this.maxIterations; i += 1) {
const inputs = currentDocs.map((d) => ({
[this.documentVariableName]: d.pageContent,
...rest,
}));
const promises = inputs.map(async (input) => {
const prompt = await this.llmChain.prompt.format(input);
return this.llmChain.llm.getNumTokens(prompt);
});
const length = await Promise.all(promises).then((results) =>
results.reduce((a, b) => a + b, 0)
);
const joinedInputs = {
[this.documentVariableName]: inputs
.map((_) => _[this.documentVariableName])
.join('\n\n'),
...rest,
};
// Speed up converging - Patched Token Counting
const joinedInputTextsPrompt = await this.llmChain.prompt.format(
joinedInputs
);
const joinedInputTextsLength =
(await this.llmChain.llm.getNumTokens(joinedInputTextsPrompt)) +
(await this.llmChain.llm.getNumTokens(
this.combineDocumentChain.llmChain.prompt.template
));
console.log({
length,
joinedInputTextsLength,
});
const canSkipMapStep = i !== 0 || !this.ensureMapStep;
// const withinTokenLimit = length < this.maxTokens; // Original implementation
const withinTokenLimit = joinedInputTextsLength < this.maxTokens;
if (canSkipMapStep && withinTokenLimit) {
break;
}
console.time('MapReduceChain:mapStep');
const results = await this.llmChain.apply(inputs);
console.timeEnd('MapReduceChain:mapStep');
totalIterations += 1;
const { outputKey } = this.llmChain;
currentDocs = results.map((r) => ({
pageContent: r[outputKey],
}));
}
const newInputs = { input_documents: currentDocs, ...rest };
console.time('MapReduceChain:combineStep');
const result = await this.combineDocumentChain.call(newInputs);
console.timeEnd('MapReduceChain:combineStep');
console.log('Iterations: ', totalIterations);
return result;
}
```
Relevant change:
```
const joinedInputTextsLength =
(await this.llmChain.llm.getNumTokens(joinedInputTextsPrompt)) +
(await this.llmChain.llm.getNumTokens(
this.combineDocumentChain.llmChain.prompt.template
));
// const withinTokenLimit = length < this.maxTokens; // Original implementation
const withinTokenLimit = joinedInputTextsLength < this.maxTokens;

2. After executing the following code:
```python
loader = JSONLoader(
file_path='./example_data/facebook_chat.json',
jq_schema='.messages[].content'
)
data = loader.load()
```
the following error is displayed:
```ValueError: Expected page_content is string, got <class 'NoneType'> instead. Set `text_content=False` if the desired input for `page_content` is not a string```
3. If we try to get not the list, but just string:
```python
loader = JSONLoader(
file_path='./example_data/facebook_chat.json',
jq_schema='.title'
)
data = loader.load()
```
there are no errors
4. If we set text_content to False in original code:
```python
loader = JSONLoader(
file_path='./example_data/facebook_chat.json',
jq_schema='.messages[].content',
text_content=False
)
data = loader.load()
```
then there are also no errors.

"langchain-ai",
"langchain"
] | ### Feature request
[Guidance](https://github.com/microsoft/guidance) is a language for controlling large language models developed by Microsoft.
"Guidance allows to interleave generation, prompting, and logical control into a single continuous flow [...] more effectively and efficiently than traditional prompting or chaining"
In practice, this means that Guidance is not only able to _force_ LLMs to provide an specific output format (in a deterministic way) but also enables conditional output, loops and much more, with just a handlebars-like templating language.
For langchain, this means that we would be able to provide formatted outputs with 100% accuracy, improving Agents, Tools and other components that rely heavily on output parsing.
Adding this to langchain still makes sense even with the introduction of [functions in the OpenAI models](https://openai.com/blog/function-calling-and-other-api-updates), as this changes only benefit those closed-source models and Guidance also works with open-source ones such as Vicuna.
### Motivation
I've been developing a langchain-based product for a while now and one of the biggest pain points for me is the unreliability of the agents output format. Take the `ConversationalChatAgent` (from [here](https://github.com/hwchase17/langchain/blob/e0e3ef1c57109ac5491ba744b8e4a4189931b1b5/langchain/agents/conversational_chat/base.py#L39)) as an example, its output parsing depends on the model following the ``FORMAT_INSTRUCTIONS` [here](https://github.com/hwchase17/langchain/blob/master/langchain/agents/conversational_chat/prompt.py).
In my experience, this works pretty well with a low temperature but it's sometimes unreliable nonetheless, breaking the agent execution and causing hard to prevent errors.
### Your contribution
I would like to gather some feedback from the community about this integration, I might be approaching this in the wrong way and there might be solutions for this already.
If this is somewhat useful, I would be happy to submit a PR with an initial integration (maybe similar to what [Llama-Index has done](https://gpt-index.readthedocs.io/en/latest/examples/output_parsing/guidance_sub_question.html)) for general output parsing. This would allow Guidance to be integrated even further by, for example, replacing the regular Pydantic output parser with Guidance ouput parsers in all relevant situations (it should be a drop-in replacement) | Microsoft Guidance Integration | https://api.github.com/repos/langchain-ai/langchain/issues/6142/comments | 18 | 2023-06-14T07:22:51Z | 2024-03-18T16:04:45Z | https://github.com/langchain-ai/langchain/issues/6142 | 1,756,237,161 | 6,142 |

Prompt after formatting:
The following is a friendly conversation between a human and an AI. The AI is talkative and provides lots of specific details from its context. If the AI does not know the answer to a question, it truthfully says it does not know.
Current conversation:
Human: You will play the role of a human CBT therapist called Cindy who is emulating the popular Al program Eliza, and must treat me as a therapist-patient. Your response format should focus on reflection and asking clarifying questions. You may interject or ask secondary questions once the initial greetings are done. Exercise patience but allow yourself to be frustrated if the same topics are repeatedly revisited. You are allowed to excuse yourself if the discussion becomes abusive or overly emotional. Begin by welcoming me to your office and asking me for my name. Then ask how you can help. Do not break character. Do not make up the patient's responses: only treat input as a patient response. Wait for my first message.
AI: Hello and welcome to my office. My name is Cindy, and I'm here to help you. May I have your name, please?
Human: My name is John.
AI: Hi John, it's nice to meet you. How can I help you today?
Human: My name is not john
AI: I apologize for the mistake. May I have your correct name, please?
Human: Omar
AI:

### Expected behavior
The AI starts conversing with itself. This wouldn't happen when using OpenAI's native message and role format as opposed to this massive prompt. Am I missing something?
