Bad keyword error

[Burhan-Q]

• This is actually a bug report.
• I am not getting good LLM Results
• I have tried asking for help in the community on discord or discussions and have not received a response.
• I have tried searching the documentation and have not found an answer.

What Model are you using?

• gpt-3.5-turbo
• gpt-4-turbo
• gpt-4
• Other (Claude, but error occurs before query)

Describe the bug
Apologies, I haven't had a ton of time to investigate, but I wanted to open a ticket before I forgot. This might actually be an error from a third party package. I was following this guide https://python.useinstructor.com/integrations/anthropic/ and when running

client = instructor.from_anthropic(
    anthropic.Anthropic(),
)

an error is raised for a bad keyword proxies for Client.__init__() and is unable to create the client object.

To Reproduce
Follow the guide

Expected behavior
Client created without error.

Patch
I was able to sidestep the issue by commenting L860 in _base_client.py but it's not obvious to me if that would cause downstream issues. After commenting this line, I was able to create the client object successfully and was able to send a query, however there were other issues but I have not ruled out external factors (my structured outputs) as the cause for those, as I ran out of time.

• Ubuntu 22.02
• Python 3.11
• Installed using uv pip install "instructor[anthropic]" command in dedicated project venv

Sorry for the rushed post. Hackathon followed by cross country travel.

Also seeing this, after trying to setup Instructor + Anthropic from the docs. Is this a dependency issue?

Appears to be an issue with the Anthropic SDK, since simply creating an instance of the Anthropic() client triggers the same error.

It's been fixed in the latest version of the Anthropic SDK (v0.40). anthropics/anthropic-sdk-python#779

The latest release of Instructor (v1.7) constrains the Anthropic SDK to versions ">=0.36.2,<0.38.0". On master 0.40 is already permitted.

The error arises from httpx. Fastest workaround is to downgrade httpx, as suggested in a comment below the anthropic issue.

Happy to close this issue as resolved, but thought it could also be helpful for other users looking for answers on the same topic. Any preference?

Have a tentative PR here that will bump anthropic up to 0.42.0 and make it the default version for people moving forward. This also allows us to support prompt caching in the normal standard message.create.

Will start working on documentation for computer use in the beta #1281

Ok I've just published instructor 1.7.2 which bumps anthropic to v0.42.0 and avoids this issue with https
