### Example Code

I have the following code and the llamafile is running on default port 8080.

```python 
from langchain_community.llms.llamafile import Llamafile

llm = Llamafile()
query1 = 'What is capital of France?'
query2 = "Tell me a joke"

for chunks in llm.stream(query1):
    print(chunks, end="")
```

The poetry file looks like below

```
[tool.poetry]
name = "exp"
version = "0.1.0"
description = ""
authors = ["Hari K T <xx@harikt.com>"]
readme = "README.md"

[tool.poetry.dependencies]
python = "^3.12"
langchain = "^0.2.16"
langchain-community = "^0.2.16"


[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"
```
