Error when testing code example for megaparsevision with Claude 3.5 Sonnet

[OSS-GR]

I was testing the megaparsevision code and I used Claude 3.5 sonnet and it spit out this error

You may be able to resolve this warning by setting `model_config['protected_namespaces'] = ()`.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Users/orestis/Repos/test_megaparser/basic_test.py", line 15, in <module>

Here is the code itself:

from langchain_anthropic import ChatAnthropic
from megaparse.core.parser.unstructured_parser import UnstructuredParser
from megaparse.core.parser.megaparse_vision import MegaParseVision
import os

# Initialize the language model
model = ChatAnthropic(model="claude-3-5-sonnet-20241022", api_key=os.getenv("ANTHROPIC_API_KEY"))

# Set up the parser
parser = MegaParseVision(model=model)
megaparse = MegaParse(parser)

# Load and process the document
response = megaparse.load("./monthly-budget-breakdown-revised.pdf")
print(response)

# Save the processed content to a markdown file
megaparse.save("./test.md")```


It worked with the UnstructuredParser so there is no issue with the API key as far as I can tell.
