API Init Requires api_key

[msharp-shop]

Describe the Bug

Running API() throws an error despite all the inputs being optional.

Expected behavior

The docs show that api_key is optional. https://www.comet.com/docs/v2/api-and-sdk/python-sdk/reference/API/#api__init__

Where is the issue?

• [x] Comet Python SDK
• [ ] Comet UI
• [ ] Third Party Integrations (Huggingface, TensorboardX, Pytorch Lighting etc)

To Reproduce

Simply run the following in a python session:

from comet_ml import API
api = API()

Stack Trace

>>> from comet_ml import API
>>> api = API()
