Santiago Delgado d84a3bcf7a Office365 Tool (#6306)
#### Background
With the development of [structured
tools](https://blog.langchain.dev/structured-tools/), the LangChain team
expanded the platform's functionality to meet the needs of new
applications. The GMail tool, empowered by structured tools, now
supports multiple arguments and powerful search capabilities,
demonstrating LangChain's ability to interact with dynamic data sources
like email servers.

#### Challenge
The current GMail tool only supports GMail, while users often utilize
other email services like Outlook in Office365. Additionally, the
proposed calendar tool in PR
https://github.com/hwchase17/langchain/pull/652 only works with Google
Calendar, not Outlook.

#### Changes
This PR implements an Office365 integration for LangChain, enabling
seamless email and calendar functionality with a single authentication
process.

#### Future Work
With the core Office365 integration complete, future work could include
integrating other Office365 tools such as Tasks and Address Book.

#### Who can review?
@hwchase17 or @vowelparrot can review this PR

#### Appendix
@janscas, I utilized your [O365](https://github.com/O365/python-o365)
library extensively. Given the rising popularity of LangChain and
similar AI frameworks, the convergence of libraries like O365 and tools
like this one is likely. So, I wanted to keep you updated on our
progress.

Xiaochao Dong a15afc102c Relax the action input check for actions that require no input (#6357)
When the tool requires no input, the LLM often gives something like
this:
```json
{
    "action": "just_do_it"
}
```
I have attempted to enhance the prompt, but it doesn't appear to be
functioning effectively. Therefore, I believe we should consider easing
the check a little bit.

Leonid Ganeline c7ca350cd3 Fix class promotion (#6187)
In LangChain, all module classes are enumerated in the `__init__.py`
file of the correspondent module. But some classes were missed and were
not included in the module `__init__.py`

This PR:
- added the missed classes to the module `__init__.py` files
- `__init__.py:__all_` variable value (a list of the class names) was
sorted
- `langchain.tools.sql_database.tool.QueryCheckerTool` was renamed into
the `QuerySQLCheckerTool` because it conflicted with
`langchain.tools.spark_sql.tool.QueryCheckerTool`
- changes to `pyproject.toml`:
  - added `pgvector` to `pyproject.toml:extended_testing`
- added `pandas` to
`pyproject.toml:[tool.poetry.group.test.dependencies]`
- commented out the `streamlit` from `collbacks/__init__.py`, It is
because now the `streamlit` requires Python >=3.7, !=3.9.7
- fixed duplicate names in `tools`
- fixed correspondent ut-s

Nathan Azrak 26ec845921 Raise an exception in MKRL and Chat Output Parsers if parsing text which contains both an action and a final answer (#5609)
Raises exception if OutputParsers receive a response with both a valid
action and a final answer

Currently, if an OutputParser receives a response which includes both an
action and a final answer, they return a FinalAnswer object. This allows
the parser to accept responses which propose an action and hallucinate
an answer without the action being parsed or taken by the agent.

This PR changes the logic to:
1. store a variable checking whether a response contains the
`FINAL_ANSWER_ACTION` (this is the easier condition to check).
2. store a variable checking whether the response contains a valid
action
3. if both are present, raise a new exception stating that both are
present
4. if an action is present, return an AgentAction
5. if an answer is present, return an AgentAnswer
6. if neither is present, raise the relevant exception based around the
action format (these have been kept consistent with the prior exception
messages)

Disclaimer:
* Existing mock data included strings which did include an action and an
answer. This might indicate that prioritising returning AgentAnswer was
always correct, and I am patching out desired behaviour? @hwchase17 to
advice. Curious if there are allowed cases where this is not
hallucinating, and we do want the LLM to output an action which isn't
taken.
* I have not passed `send_to_llm` through this new exception

Fixes #5601

Zeeland b72401b47b pref: reduce DB query error rate (#5339)
# Reduce DB query error rate

If you use sql agent of `SQLDatabaseToolkit` to query data, it is prone
to errors in query fields and often uses fields that do not exist in
database tables for queries. However, the existing prompt does not
effectively make the agent aware that there are problems with the fields
they query. At this time, we urgently need to improve the prompt so that
the agent realizes that they have queried non-existent fields and allows
them to use the `schema_sql_db`, that is,` ListSQLDatabaseTool` first
queries the corresponding fields in the table in the database, and then
uses `QuerySQLDatabaseTool` for querying.

There is a demo of my project to show this problem.

**Original Agent**

```python
def create_mysql_kit():
    db = SQLDatabase.from_uri("mysql+pymysql://xxxxxxx")
    llm = OpenAI(temperature=0)

    toolkit = SQLDatabaseToolkit(db=db, llm=llm)
    agent_executor = create_sql_agent(
        llm=OpenAI(temperature=0),
        toolkit=toolkit,
        verbose=True
    )
    agent_executor.run("Who are the users of sysuser in this system? Tell me the username of all users")


if __name__ == '__main__':
    create_mysql_kit()

```

**original output**

```

As you can see, agent always use incorrect sql to query the data.
Actually, the username field name of my `app_sysuser` table is
`user_name`, not the `username` believed by the agent.

Zander Chase 14099f1b93 Use Default Factory (#5380)
We shouldn't be calling a constructor for a default value - should use
default_factory instead. This is especially ad in this case since it
requires an optional dependency and an API key to be set.
 
Resolves #5361

Deepak S V c6e5d90eff Fixing blank thoughts in verbose for "_Exception" Action (#5331)
Fixed the issue of blank Thoughts being printed in verbose when
`handle_parsing_errors=True`, as below:

Before Fix:
```
Observation: There are 38175 accounts available in the dataframe.
Thought:
Observation: Invalid or incomplete response
Thought:
Observation: Invalid or incomplete response
Thought:
```

After Fix:
```
Observation: There are 38175 accounts available in the dataframe.
Thought:AI: {
    "action": "Final Answer",
    "action_input": "There are 38175 accounts available in the dataframe."
}
Observation: Invalid Action or Action Input format
Thought:AI: {
    "action": "Final Answer",
    "action_input": "The number of available accounts is 38175."
}
Observation: Invalid Action or Action Input format
```

@vowelparrot currently I have set the colour of thought to green (same
as the colour when `handle_parsing_errors=False`). If you want to change
the colour of this "_Exception" case to red or something else (when
`handle_parsing_errors=True`), feel free to change it in line 789.

Alexander Dibrov d8eed6018f Output parsing variation allowance (#5178)
# Output parsing variation allowance for self-ask with search

This change makes self-ask with search easier for Llama models to
follow, as they tend toward returning 'Followup:' instead of 'Follow
up:' despite an otherwise valid remaining output.

Eduard van Valkenburg 1cb04f2b26 PowerBI major refinement in working of tool and tweaks in the rest (#5090)
# PowerBI major refinement in working of tool and tweaks in the rest

I've gained some experience with more complex sets and the earlier
implementation had too many tries by the agent to create DAX, so
refactored the code to run the LLM to create dax based on a question and
then immediately run the same against the dataset, with retries and a
prompt that includes the error for the retry. This works much better!

Also did some other refactoring of the inner workings, making things
clearer, more concise and faster.

Deepak S V 5cd12102be Improving Resilience of MRKL Agent (#5014)
This is a highly optimized update to the pull request
https://github.com/hwchase17/langchain/pull/3269

Summary:
1) Added ability to MRKL agent to self solve the ValueError(f"Could not
parse LLM output: `{llm_output}`") error, whenever llm (especially
gpt-3.5-turbo) does not follow the format of MRKL Agent, while returning
"Action:" & "Action Input:".
2) The way I am solving this error is by responding back to the llm with
the messages "Invalid Format: Missing 'Action:' after 'Thought:'" &
"Invalid Format: Missing 'Action Input:' after 'Action:'" whenever
Action: and Action Input: are not present in the llm output
respectively.

For a detailed explanation, look at the previous pull request.

New Updates:
1) Since @hwchase17 , requested in the previous PR to communicate the
self correction (error) message, using the OutputParserException, I have
added new ability to the OutputParserException class to store the
observation & previous llm_output in order to communicate it to the next
Agent's prompt. This is done, without breaking/modifying any of the
functionality OutputParserException previously performs (i.e.
OutputParserException can be used in the same way as before, without
passing any observation & previous llm_output too).

local/remote SparkSession.
* Include a notebook example

I tried some complicated queries (window function, table joins), and the
tool works well.
Compared to the [Spark Dataframe

agent](https://python.langchain.com/en/latest/modules/agents/toolkits/examples/spark.html),
this tool is able to generate queries across multiple tables.

Chakib Ben Ziane 5525b704cc Chatconv agent: output parser exception (#4923)
the output parser form chat conversational agent now raises
`OutputParserException` like the rest.

The `raise OutputParserExeption(...) from e` form also carries through
the original error details on what went wrong.

I added the `ValueError` as a base class to `OutputParserException` to
avoid breaking code that was relying on `ValueError` as a way to catch
exceptions from the agent. So catching ValuError still works. Not sure
if this is a good idea though ?

Richard He 7642f2159c Add human message as input variable to chat agent prompt creation (#4542)
# Add human message as input variable to chat agent prompt creation

This PR adds human message and system message input to
`CHAT_ZERO_SHOT_REACT_DESCRIPTION` agent, similar to [conversational
chat
agent](https://github.com/hwchase17/langchain/blob/7bcf238a1acf40aef21a5a198cf0e62d76f93c15/langchain/agents/conversational_chat/base.py#L64-L71).

I met this issue trying to use `create_prompt` function when using the
[BabyAGI agent with tools
notebook](https://python.langchain.com/en/latest/use_cases/autonomous_agents/baby_agi_with_agent.html),
since BabyAGI uses “task” instead of “input” input variable. For normal
zero shot react agent this is fine because I can manually change the
suffix to “{input}/n/n{agent_scratchpad}” just like the notebook, but I
cannot do this with conversational chat agent, therefore blocking me to
use BabyAGI with chat zero shot agent.

I tested this in my own project
[Chrome-GPT](https://github.com/richardyc/Chrome-GPT) and this fix
worked.

This reverts commit 5111bec540.

it also didn't update the synchronous API correctly, which makes it
error-prone (the behavior of the async and sync endpoints would be
different)
