Being a seasoned Artificial Intelligence expert, I am very well-versed with the practicalities of model training and debugging, which aligns closely with your project's requirements. Over my 12-year career, I have continually worked on projects that demanded strong expertise in utilizing libraries like TensorFlow, Keras and PyTorch for developing AI-powered solutions. This makes me fully capable of not just identifying but also precisely rectifying the issue causing the 'Invalid File' error in your AudioDeepFakeDetection Model.
As an AI professional, I have had substantial experience working with various file formats including WAV audio files, giving me an added advantage in understanding and resolving problems related to them. My skills extend to a wide range of deep learning domains such as computer vision, natural language processing, etc., which further consolidates my prowess for problems such as the one you're tackling.
To ensure transparency and leverage the shared knowledge, I will be utilizing the source code from your provided Github link. Rest assured, post-rectification, all functioning codes shall be delivered to you promptly. Trust me with this endeavor; with your challenge and my expertise togther we will overcome this hurdle effectively by delivering a fully operational AudioDeepFakeDetection Model that accurately trains on WAV audio files and eliminates the 'Invalid File' error you've been encountering. Let's get started!
