Langchain instructions give errors about missing generate() method

[mspertus]

When I follow the instructions for using the langchain Eleven Labs Text2SpeechTool here, I get the following error.

Type "help", "copyright", "credits" or "license" for more information.
>>> from langchain_community.tools import ElevenLabsText2SpeechTool
>>>
>>> text_to_speak = "Hello world! I am the real slim shady"
>>>
>>> tts = ElevenLabsText2SpeechTool()
>>> speech_file = tts.run(text_to_speak)
Traceback (most recent call last):
  File "C:\Users\mike\anaconda3\envs\baseClone\Lib\site-packages\langchain_community\tools\eleven_labs\text2speech.py", line 58, in _run
    speech = elevenlabs.generate(text=query, model=self.model)
             ^^^^^^^^^^^^^^^^^^^
AttributeError: module 'elevenlabs' has no attribute 'generate'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\mike\anaconda3\envs\baseClone\Lib\site-packages\langchain_core\tools.py", line 422, in run

    raise RuntimeError(f"Error while running ElevenLabsText2SpeechTool: {e}")
RuntimeError: Error while running ElevenLabsText2SpeechTool: module 'elevenlabs' has no attribute 'generate'

My langchain package versions are langchain-0.1.14, langchain-community-0.0.31, langchain-core-0.1.38, langchain-text-splitters-0.0.1 langsmith-0.1.38 and my elevenlabs version is 1.0.3. I believe I followed the instructions in the langchain docs above correctly.

Any advice appreciated, Mike

@mspertus it looks like langchain hasn't upgraded to v1.x of the SDK (there were some breaks from v0.x to v1.x).

You can lower the version of elevenlabs to below 1.0. I have tried multiple times and found that the properties have not been changed above 1. x example: pip install --upgrade elevenlabs==0.2.27, it's workful for me.
