[BUG] Numerous `ibm_watson_machine_learning` regex syntax warnings.

[deanwampler]

Is there an existing issue for this?

Current Behavior

I don't know if this prevents it from working correctly (at the moment, I can't run the 01-responses notebook...), but the library ibm_watson_machine_learning is throwing a lot of regex errors when Llama Stack is started. I'm using uv to manage dependencies and run it:

uv run llama stack run run.yaml --image-type venv

Here are the syntax warnings:

I tried removing the ibm_watson_machine_learning dependency to see if things run cleanly, but couldn't successfully do it. I hit some errors in the watsonx integration with Llama Stack, when it couldn't find this library.
