Hi,
Thank you for providing with amazing solution on new modules.
The problem I am facing with your code is :
NameError Traceback (most recent call last)
[](https://localhost:8080/#) in ()
3 from llmx.generators.text.textgen import sanitize_provider
4
----> 5 lida = Manager(text_gen = llm("openai", api_key='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')) # !! api key
6 textgen_config = TextGenerationConfig(n=1, temperature=0.5, model="gpt-3.5-turbo-0301", use_cache=True)
7

[/usr/local/lib/python3.10/dist-packages/llmx/generators/text/textgen.py](https://localhost:8080/#) in llm(provider, **kwargs)

51 if provider.lower() == "openai":
---> 52 return OpenAITextGenerator(**kwargs)
53 elif provider.lower() == "palm":
54 return PalmTextGenerator(**kwargs)

NameError: name 'OpenAITextGenerator' is not defined.

Can you please help me resolve.
