class TestScene(VoiceoverScene):
    def construct(self):
        self.set_speech_service(ElevenLabsService(
            voice_name="Adam",
            api_key="your_api_key_here",
            transcription_model=None
        ))

Additional comments

The issue stems from manim-voiceover using the deprecated pkg_resources API in its __init__.py file. The solution would be to migrate to importlib.metadata which is the recommended replacement. This affects all users with recent setuptools versions and will become a breaking issue when setuptools 81+ removes pkg_resources entirely.
