`create_iterable` is broken

[shaunstoltz]

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

i am facing the same issue, have you figured out how to fix it?

This issue was fixed in #710, with the relevant changes found here:

instructor/instructor/dsl/simple_type.py

Lines 40 to 48 in 081418d

	try:
	if isclass(response_model) and issubclass(response_model, BaseModel):
	return False
	except TypeError:
	# ! In versions < 3.11, typing.Iterable is not a class, so we can't use isclass
	# ! for now if `response_model` is an Iterable isclass and issubclass will raise
	# ! TypeError, so we need to check if `response_model` is an Iterable
	# ! This is a workaround for now, we should fix this in later PRs
	return False

I’ve verified that the example now runs without any problems. It’s safe to close this issue.

I still face the same problem and the error happens like below in version 1.3.2 (latest).

issubclass() arg 1 must be a class ... TypeError: issubclass() arg 1 must be a class

class GeminiClient:
    def __init__(self):
        genai.configure(api_key=GOOGLE_API_KEY)
        self.model = client_gemini.from_gemini(
            client=genai.GenerativeModel(model_name="models/gemini-1.5-flash-latest"),
            mode=Mode.GEMINI_JSON
        )

class ScenarioTelop(BaseModel):
    telop_id: int = Field(description="Order of the telop (starting from 1)")
    overview: str = Field(description="Overview of the telop")
    intention: str = Field(description="Intention of the telop")
    text: str = Field(description="Corrected text of the telop")
    original_text: str = Field(description="Original text of the telop")
    timestamp_start: float = Field(description="Start timestamp of the telop (s)")
    timestamp_end: float = Field(description="End timestamp of the telop (s)")

what version of python are you on?

what version of python are you on?

3.9.18

[ivanleomk]

Proposed a potential fix for this #737 - can't seem to get the 3.11 coverage step to pass for some reason but the iterable fix is shown to work in 3.9,3.10 and 3.11

Fixed in #737
