create_iterable is broken

[bryanhpchiang]

create_iterable from the docs does not work.

1. Go here: https://python.useinstructor.com/#streaming-iterables-create_iterable
2. Copy + paste + run the example
3. Error

Same for me:

    client = instructor.from_litellm(completion)


   completion_return = client.chat.completions.create_iterable(
        messages=[{"role": "user", "content": prompt}],
        response_model=task_decomp,
        model=model,
      )

Error: issubclass() arg 1 must be a class

class task_decomp(BaseModel):
    index: int
    description: str
    duration: int
    left: int
