Original GitHub issue: https://github.com/RVC-Project/Retrieval-based-Voice-Conversion/issues/38

I am trying to access the RVC API method infer_convert using the Gradio client, but I am encountering issues with the F0 curve file. I have tried using None and empty string and other files, but it still does not work. Could you please provide an example or guidance on how to properly use the F0 curve file with this API?
