Confused about dependency handling

[Koeng101]

Why is both poetry and pip used? Shouldn't dependencies be handled by poetry, then after poetry install run with poetry run python main.py?

When I do try that, I get the error of no litellm, but when I try to add it, I get:

Because no versions of litellm match >1.7.12,<2.0.0
 and litellm (1.7.12) depends on openai (>=1.0.0), litellm (>=1.7.12,<2.0.0) requires openai (>=1.0.0).
So, because gpt-migrate depends on both openai (^0.27.8) and litellm (^1.7.12), version solving failed.

When I do use pip for installing the dependencies, I get the following error:

Traceback (most recent call last):
  File "/Users/koeng/py/src/github.com/joshpxyne/gpt-migrate/gpt_migrate/main.py", line 7, in <module>
    from ai import AI
  File "/Users/koeng/py/src/github.com/joshpxyne/gpt-migrate/gpt_migrate/ai.py", line 6, in <module>
    from litellm import completion
  File "/opt/homebrew/lib/python3.11/site-packages/litellm/__init__.py", line 28, in <module>
    from .timeout import timeout
  File "/opt/homebrew/lib/python3.11/site-packages/litellm/timeout.py", line 11, in <module>
    from openai.error import Timeout
ModuleNotFoundError: No module named 'openai.error'

Which I solved with pip install --upgrade litellm==1.0.0. This is a little suspicious since it is one of the only frozen dependencies... requirements.txt:

typer
langchain
yaspin
openai
tree_sitter
litellm==0.1.213
pydantic==1.10.8

So, what's up with mixing poetry and pip?
