`embedder_model` AttributeError in `/examples/openai/deep_scraper_openai.py`

[ajt]

Describe the bug When running the OpenAI Deep Scraper example located at examples/openai/deep_scraper_openai.py, I get the error:

Traceback (most recent call last):

AttributeError: 'DeepScraperGraph' object has no attribute 'embedder_model'

To Reproduce Steps to reproduce the behavior: Fresh install on macOS. Execute the script

Expected behavior Expecting the script to execute without errors.

Desktop (please complete the following information):

• OS: MacOS 13.6.7
• Browser chrome

Additional context I am sure that the embedder_model just needs to be set, but I am unsure how to do it.
