[alexanderchiu]

Describe the bug Wasn't able to pip install and run openbb.

Traceback (most recent call last):

To Reproduce python3.10.9 -m venv . pip install openbb openbb

Desktop (please complete the following information):

• OS: Fedora 38
• Python version 3.10.9

Additional context Was able to get it working by pinning openai to 0.28.1

pip install openai==0.28.1

I'm assuming the latest open ai release broke something: https://pypi.org/project/openai/#history.
