sleep_results = bp.sleep.sleep_processing_pipeline.predict_pipeline_acceleration( data, sampling_rate=60)

Hi, can you please provide more information on the problem? A screenshot of the error message to see in which line exactly the error occurred would already help a lot...

AttributeError: 'numpy.ndarray' object has no attribute 'index'

I don't understand why an error occurs even though that dataframe have an index.
