AutoGPT example finding Winning Marathon Times

• Implementation of https://github.com/Significant-Gravitas/Auto-GPT
• With LangChain primitives (LLMs, PromptTemplates, VectorStores, Embeddings, Tools)

Set up tools

• We'll set up an AutoGPT with a search tool, and write-file tool, and a read-file tool, a web browsing tool, and a tool to interact with a CSV file via a python REPL

Define any other tools you want to use below:

AutoGPT for Querying the Web

I've spent a lot of time over the years crawling data sources and cleaning data. Let's see if AutoGPT can help with this!

Here is the prompt for looking up recent boston marathon times and converting them to tabular form.

Thought: The CSV file has already been read and saved into a pandas dataframe called `df`. Hence, I can simply display the data by printing the whole dataframe. Since `df.head()` returns the first 5 rows, I can use that to showcase the contents.

Action: python_repl_ast
Action Input: print(df.head())   Year                               Name Country     Time
0  2022                       Evans Chebet   Kenya  2:06:51
1  2021                     Benson Kipruto   Kenya  2:09:51
2  2020  Canceled due to COVID-19 pandemic     NaN      NaN
3  2019                   Lawrence Cherono   Kenya  2:07:57
4  2018                      Yuki Kawauchi   Japan  2:15:58

Observation: None
Thought:I used the wrong tool to perform the action. I should have used the given data and not interacted with the Python shell. I can now provide the displayed data as the answer since the information in the printed dataframe would look like a table when typed as text.

Final Answer: 
   Year                               Name Country     Time
