This notebook goes over how to use the arxiv component.
First, you need to install arxiv python package.
!pip install arxiv
from langchain.chat_models import ChatOpenAI
from langchain.agents import load_tools, initialize_agent, AgentType
llm = ChatOpenAI(temperature=0.0)
tools = load_tools(
    ["arxiv"], 
)
agent_chain = initialize_agent(
    tools,
    llm,
    agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION,
    verbose=True,
)
agent_chain.run(
    "What's the paper 1605.08386 about?",
)

I need to use Arxiv to search for the paper.

Title: Heat-bath random walks with Markov bases
Authors: Caprice Stanley, Tobias Windisch
Summary: Graphs on lattice points are studied whose edges come from a finite set of
allowed moves of arbitrary length. We show that the diameter of these graphs on
fibers of a fixed integer matrix can be bounded from above by a constant. We
then study the mixing behaviour of heat-bath random walks on these graphs. We
also state explicit conditions on the set of moves so that the heat-bath random
walk, a generalization of the Glauber dynamics, is an expander in fixed
dimension.
Thought:The paper is about heat-bath random walks with Markov bases on graphs of lattice points.
Thought:The paper is about heat-bath random walks with Markov bases on graphs of lattice points.
Final Answer: The paper 1605.08386 is about heat-bath random walks with Markov bases on graphs of lattice points.

The ArXiv API Wrapper#
The tool wraps the API Wrapper. Below, we can explore some of the features it provides.
from langchain.utilities import ArxivAPIWrapper
Run a query to get information about some scientific article/articles. The query text is limited to 300 characters.
It returns these article fields:
Publishing date
Title
Authors
Summary
Next query returns information about one article with arxiv Id equal “1605.08386”.
arxiv = ArxivAPIWrapper()
docs = arxiv.run("1605.08386")

Now, we want to get information about one author, Caprice Stanley.
This query returns information about three articles. By default, the query returns information only about three top articles.

'Published: 2017-10-10\nTitle: On Mixing Behavior of a Family of Random Walks Determined by a Linear Recurrence\nAuthors: Caprice Stanley, Seth Sullivant\nSummary: We study random walks on the integers mod $G_n$ that are determined by an\ninteger sequence $\\{ G_n \\}_{n \\geq 1}$ generated by a linear recurrence\nrelation. Fourier analysis provides explicit formulas to compute the\neigenvalues of the transition matrices and we use this to bound the mixing time\nof the random walks.\n\nPublished: 2016-05-26\nTitle: Heat-bath random walks with Markov bases\nAuthors: Caprice Stanley, Tobias Windisch\nSummary: Graphs on lattice points are studied whose edges come from a finite set of\nallowed moves of arbitrary length.

An\nagreement of calculated fluxes with data on charged particles from the AMS and\nCAPRICE detectors is demonstrated. Predictions on neutrino fluxes at different\nexperimental sites are compared with results from other calculations.'
Now, we are trying to find information about non-existing article. In this case, the response is “No good Arxiv Result was found”
