Thanks for the contribution! I think you may need to control the scope of modified files. Multiple files irrelevant to this PR are modified. I think maybe only the notebook itself should be modified. You can follow the contribution guidelines here: https://microsoft.github.io/autogen/docs/contributor-guide/contributing/

Hi @teilomillet, thanks for creating this.

I've tried to run it with the current Anthropic library, v0.28.0 and I can't run the second cell:

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
Cell In[5], [line 16](vscode-notebook-cell:?execution_count=5&line=16)
     [14] TOOL_ENABLED = anthropic_version >= "0.23.1"
     [15] if TOOL_ENABLED:
---> [16]     from anthropic.types.beta.tools import ToolsBetaMessage
     [17] else:
     [18]     ToolsBetaMessage = object

ModuleNotFoundError: No module named 'anthropic.types.beta'

Just checking if it's working for you?

I am trying to make this work, and no, it's not working for me, same error I guess

ModuleNotFoundError Traceback (most recent call last)
in <cell line: 15>()
14 TOOL_ENABLED = anthropic_version >= "0.23.1"
15 if TOOL_ENABLED:

17 else:
18 ToolsBetaMessage = object

ModuleNotFoundError: No module named 'anthropic.types.beta'

It is an improvement but it doesn't seem to fully resolve issues, which I believe are associated with Autogen's underlying reliance on the OpenAI format.

For example, if I run the two-agent example here, I get the following error:

BadRequestError: Error code: 400 - {'message': 'messages: roles must alternate between "user" and "assistant", but found multiple "user" roles in a row'}
